Is Notebook A Better Choice Than Desktop?

by: Roberto Sedycias

If internet made the world a global village, then we might as well say that notebooks made it a global colony. With desktops, things were a click away from us; notebook shorted the distance. Now we can carry the global colony on our shoulder. High-end technology at your lap, perhaps, we need nothing to conquer the world of convergence.

The great advantage of notebooks is that it gives us a sense of portability and mobility. Looking critically, portability is the only feature, a notebook has over desktops then why do we choose to go for a notebook? Notebooks can let you carry your work conveniently and you do not have to worry about all the wires, hardware and space required to keep a desktop. Also it's a matter of choice between work and home. You may want to work from home, when your baby or wife is ill. A notebook comes in handy then.

A notebook has a different role to play for different people, but it gives an incredible sense of freedom. Gone are the days when people walked around with pen and paper. All you need to do today to make notes it to buy a notebook. You may want to quickly write a email to a radio station, which is making noise in the name of music. You may want to sit in your neighborhood coffee shop and write a book or letter. But if you want to carry your notebook everywhere you go, you have to consider the weight of the machine too. A notebook weighs between 5 to 10 pounds; an ultralight model is even lighter. Whereas, a desktop computer, with its standalone CPU, monitor, and keyboard, weighs in at about 70 pounds. A notebook takes much lesser space too and is very convenient.

Some of the most famous notebooks are Sony Vaio, Apple MacBook, Dell Latitude, Toshiba, HP. Also there are many affordable versions of notebooks marketed by companies like Fujitsu, Panasonic, IBM, Asus and etc.

Let's look at a scenario where at a school, students are quietly seated at their desks and working on a class assignment with no teachers to guide them. It's real, and is happening in many schools around us. Now, we don't have to mourn looking at our tiny ones carrying pounds of baggage in their backs. Notebook has it all, from their books to assignment copies.

When we look at the productive side of the picture, we would promptly realize that a notebook is always a wise choice for an employer too. It makes his or her employees to achieve more productivity at work. It saves critical office space. At any crucial moment, a notebook can help you to do the work, even when you are not physically present in the office. When the traffic is high, and your boss is waiting for presentation in a conference room, a notebook comes to the rescue. A desktop PC does not give all this freedom for a good worker.

A research says that employees with notebooks work more than those companies with desktop PCs. A notebook enables you to work from anywhere, while traveling, from a beauty parlor, or while waiting for someone at a shopping mall. And the only disadvantage a notebook has is its safety, unless you doubly assure it from theft. It's easy to pick and elope for anyone at a busy commercial place. So, ensure the safety of your costly gadget that makes you feel the world is at your feet and enjoy the power of technology.

Notebook Buying Tips

by: Roberto Sedycias

Why notebook became so popular? It has been estimated that notebook sales has increased an average of 20% per year in the United States alone. Among the many advantages it offers, portability is one of the main reason people end up making a purchase of it. However before any purchase is made, other features should be considered as well.

Notebook was first made available in the early eighties. Although much heavier and bulkier than today's notebooks, it had the unique portability feature that put this innovative product in a class by itself. Although not much of a commercial success then, it gave the computer industry a goal to pursue in manufacturing this item with better weight, size and performance ratio and making one of today's most wanted computer hardware.

Notebook size has got much smaller, however big enough to make one feel very comfortable in handling and operating computer related tasks. One can find it in sizes best categorized as: 1 - Tablet Pc has the size of paper tablet and weighs no more than 4 pounds; 2 - Ultra Portable is a little bigger than Tablet Pc and weighs around 4 pounds, no internal CD or DVD drive, display of 12 inches or smaller; 3 - Thin and Light is a mid-size notebook, 10-14" x 10", 1 to 1.5 thick, and weighs around 7 pounds, wireless network capability, 14-inch displays, combo CD-RW/DVD; 4 - Desktop replacement is the largest category of notebooks, more than 12 x 10" and weighs more than 7 pounds, 15-17 inches displays or larger, wireless network capability, combo CD-RW/DV.

Also an important feature one should look for is performance. Notebooks provide very close performance in comparison with traditional desktop computers, and should handle all computer related tasks with great ease. Whenever purchasing a notebook, make sure it has the latest cpu model, large ram memory and hard disk space. Notebook performance is directly related with cpu clock, ram memory and hard disk space. For these items, big is never enough.

Another feature one should look for is the dvd player. It can come in handy for entertainment purposes, enabling one to watch movies while traveling. Wireless connection is also a feature to look for in a notebook. Some notebooks feature an infrared port, which can be used to connect a mobile phone. Also there are other wireless technologies such as Bluetooth and Wi-Fi, which allows mobile phone, printers and PDA to be connected at certified public and private network. The ability to have a mobile connection is definitely a plus in today's connected world.

Expansion capability for notebooks can be done thru the use of plug-in pc cards. Although there is a new standard called ExpressCard, which is smaller and faster plug-in card that provides more features for multimedia tasks.

Notebooks have certainly become an item required for one's mobile computer related tasks, whether it is used for public, private, personal or professional purposes. Its portability and small size make an attractive all around computer hardware item. For those looking for mobile computer hardware, notebooks can certainly become a good solution at affordable prices.

Types Of Notebook Computers

by: Roberto Sedycias

Notebook, notebook computer, laptop, and laptop computer are different terms for a small computer, which is mobile, and weighing about 1 to 6 kg or 2.2 to 18 pounds, depending upon the model. In 1979-1980, Bill Moggridge of GRiD Systems Corp. designed one of the first laptops and named it as the GRiD Compass 1101. It featured the clamshell design where the flat display folded shut on the keyboard. In May 1983, Gavilan Computer Corp. introduced and first marketed as a laptop, known as Gavilan SC. About this same time, Sharp Corp.Ltd., announced their laptop Sharp PC-5000.

In 1989, Compaq introduced Compaq LTE, which was a laptop of a smaller size, about the size of an A4 paper notebook, and it popularly came to be known as a notebook computer or notebook. Thereafter the terms laptop and notebook began to be used interchangeably. Nevertheless, the terms, notebook and laptop are incorrect terms, as due to the heat, many laptops cannot be placed on top of the lap, and most notebooks are not the size of an A4 paper notebook. However, what manufacturers usually call as a notebook, end-users prefer to call it as a laptop; hence both the terms are used.

According to the functions and the models of notebooks, they are generally classified as: Ultraportables (screen is diagonally less than 12 inches, weight is 1.7 kg or less); thin-and lights (screen is diagonally from 12 to 14 inches, weight is from 1.8 to 2.8 kg); medium-sized laptops (screen is diagonally from 14 to 15.4 inches, weight is from 3 to 3.5 kg); and desktop replacement computers (screen is diagonally from 17 to 20 inches, weight is 4 to 6 kg).

The concept of laptop was to make a device that could use the same software of a desktop computer, but much smaller in size to enable mobility and support mobile computing (ability to use the computer while in transit). Thus, further innovations have introduced transportables (which can be moved from one place to another without supporting mobile computing); tablets (which feature touchscreens and support mobile computing); ultra mobile PCs (which are very small and compact tablet PCs); internet tablets (which support internet and mobile computing); personal digital assistants (PDAs), which are pocket-sized and support mobile computing; handheld computers, which represent expensive tablets or PDAs; and smartphone, which is a PDA or a handheld computer with cellphone integration. Over the development phases, these classifications got blurry at times, and many machines fused functionalities of other categories.

Notebooks can be used for various purposes. Commercial purposes like attending phone calls, receiving and sending emails and faxes, typing out letters and printing them, making presentations with pie and bar charts, and taking data from one place to another can be achieved by any standard notebook. However, high fliers prefer thin-and-light notebooks and for regular office work, ultraportable notebooks are preferred. Both are wireless notebooks so they can be remotely accessed. Scientific purposes are best suited with a notebook that features fast computing speed, good 2D and 3D graphics display, and a large memory, like desktop replacement notebook, and a thin-and-light notebook. Artistic purposes require animation, 2D and 3D drawings, interior & exterior designing, arranging music compositions, post-production audio-video work, etc., which can be fulfilled by desktop replacements, gaming notebooks, and mainstream notebooks.

Educational institutions normally do not prefer notebooks due to its high chance of being stolen. Additionally, they prefer that their assets do not move around within the premises in the hands of students who may be careless. However, to keep up with the times, and to be considered as techno-savvy, they do invest in notebooks. The types of notebooks best suited for educational purposes are mainstream notebooks, and desktop replacements. Students need a notebook to do projects, prepare study notes, and to play some games in their spare time. They need to take the notebook wherever they go, hence, size and weight are major considerations. The type of notebook that fulfills student needs is a thin-and-light notebook with locking facility so that they can lock it with their backpack. Most students report late submission of projects due to their notebooks being stolen.

So no matter what the purpose one might have for using a notebook, it seems that mobility will always seem to be the main reason for such a product purchase. Nowadays with so many models being offered with affordable prices, it seems that notebooks will always be a product in demand. After all it is one of the best selling computer hardware for quite some time. And that says it all.

Computer Diagnostics

by: John Ugoshowa

The diagnostics that are associated with computers can help to identify any problem or failure that computers show when they are having problems. Diagnostics are used to test out the computer system, which includes both the BIOS and memory, software, and even the hardware that is attached to the computer.

The most common types of problems will occur when your computer is down to very low resources, which can either be a low amount of RAM, or a low disk space. These conditions are very common, and generally result in your computer running very slow. This can easily be fixed, all you have to do is defrag your hard drive, and get rid of some programs and files that you no longer use or need.

Almost all types of computer diagnostic software can find and fix just about any problem that you are having. It normally starts off with a BIOS examination, and goes on from there. PC diagnostics software can determine a lot from the BIOS, from the common settings to those that have a major impact on both boot up and performance.

No matter what you do, you should never modify or tamper with the BIOS settings, as it can lead to serious problems. If you do plan to modify or mess with your BIOS, you should always create a backup first, just in case something goes wrong. The BIOS settings can be very tricky, although they are responsible for a lot to do with your computer. If you have never been in the BIOS before, you really shouldn’t be modifying anything inside of it.

Depending on the diagnostics program that you are using, there will be several different features available. Right now, two of the most popular are Norton Systemworks and PC Doctor. Both of these programs offer full diagnostics software, good for fixing just about any software related computer program you can imagine.

Once you run the program, you’ll be able to select the diagnostic test that you are planning to run. Some offer you a full system scan, which will scan your entire computer and then display any problems that you having. After displaying any problems, the software will normally give you an option to go ahead and fix it. As long as the problem is nothing serious, the diagnostic software can generally fix it.

The more complicated problems, such as hardware failures or hard drive crashes, are a totally different story. They will require a technician who is very experienced, that can rebuild the hardware. Diagnostic software can report hardware problems to you, although most of the time it is unable to fix it.

There are other computer diagnostic software that you run after starting the computer or rebooting, that will check everything from BIOS. These types are great, although the types such as Norton and PC Doctor are by far superior. They offer far more features, including defragment, cache cleaner, and the option to delete your temporary Internet files. These features are great to have, especially if you aren’t the technical type.

For more reasons than one, computer diagnostic software is the ideal way to find and prevent problems with your computer. Norton Systemworks offers you Ghost as well, which is the perfect way to back up your data. You can back up certain files, or just go ahead and back up your entire hard drive. Systemworks and Ghost are very easy to use, even if you are completely new to computers. For everything they offer you - computer diagnostic programs are the ideal way to prevent problems before they happen.

Backup Data On Your Laptop

by: John Ugoshowa

If you were to look at past statistics regarding the information that has been lost in regards to laptop computers, you would find yourself amazed. Even though this information can be astounding, many of us still don’t take the time to back up the information on our laptops.

To put it in simple terms, nothing in the computer industry is fool proof. Hard drives can crash, the laptop can get stolen, or it can even be dropped and rendered useless. To ensure that we are never left without our precious data, we should always create a backup of our information.

There is no mistaken the fact that over a million laptops have been stolen over the years in the United States alone. Anytime a laptop is stolen, chances are that it won’t be recovered. If the information wasn’t backed up, then the owner will be left with no laptop - but more importantly - no backed up data either.

Just like you can with desktop computers, you can also create a backup of the data on your laptop as well. You can use online services, back it up remotely, or use several other methods to ensure that you keep all of your data. Preserving your data is something you should really look into, especially if you have business material on your laptop.

The best way to go about backing up your data and files is to burn them to a data CD. Data CDs can hold up to 700 MB (Mega Bytes) of data, which means a lot of files. To back things up this way, all you need is a CD/RW burner in your laptop, which most of the newer ones come with.

The only drawback to laptops is the fact that they don’t offer near as much storage or security measures as a desktop PC. Desktop computers have a lot more power, and they can also do things (including backups) in a fraction of the time.

The laptop computer was designed for on the go use, which is the main reason why people don’t really think about backing up their data. When the thought finally does come to mind, it is normally too late to do anything about it.

As mentioned above, the easiest and quickest way to backup your laptop data is to use an online backup service. Depending on your connection to the Internet, it can take anywhere from several minutes to several hours. Although it may take you a little bit of time, you’ll have the satisfaction in knowing that your data is there if something should happen.

Whether it’s for your business or personal use, you can’t go wrong backing up your data. You should always create a backup of your data at least once a month, even more than that if you have a lot of important information that you add to your laptop on a frequent basis.

Wireless Network Security

by: Jake Forrester

It seems that more and more home users are going with wireless networks rather than the tradition wired networks with wires hanging everywhere and running wild around the house and in the crawlspace. What seems like a good idea quickly turns into a nightmare if you don’t vamp up the security of your wireless network.

Speed is of the essence. Typically, one thing matters to new users of wireless, getting connected and browsing that first website. While wireless connectivity can accomplish this, it’s best to set up your wireless connection securely before venturing out into cyberspace. Below are some tips to help secure your wireless network.

Change the default admin password. Admin passwords are easily figured out by attackers when they are left as the default. Not changing your wireless admin password opens your network to attack and can lead to many problems depending on the attacker’s agenda.

Another wireless security measure you will need to take is turning on encryption. Enabling WEP encryption on your wireless network will help you protect your privacy and all your info won’t be floating around outside your home waiting to be picked up by a passerby. It’s important to remember that all your devices on the wireless network will need to have the same encryption. So find the strongest encryption possible that will work on all devices of the wireless network.

Stop the auto-connect feature. Do not allow your devices to auto-connect. Allowing auto-connect may connect to a network that you don’t particularly want. Example, you don’t want your laptop connecting to your neighbor’s network and sending info.

It’s also a good idea that you install firewalls on all devices that connect to the wireless network. Even if the wireless router is firewalled, it’s important to also install firewalls on all computers that are connected to the wifi network. It’s important that these firewalls be set up correctly and block any intrusions that may compromise your wifi network.

Position your wireless router close to the center of your home. Although the reach of wifi networks can vary greatly, it’s important to not allow the signal to float around great distances from the main access point. It virtually impossible to stop all leakage from exiting your home. But minimizing the risk to your wifi network will help to protect it.

Another good idea for wifi network security is to not allow broadcast of the SSID. Your router may have SSID broadcasting set up by default; however you should be able to change this setting in the configuration. This feature is only useful for mobile environments, and is not needed in home wifi networks.

These are just a few tips to securing your wifi network. It’s always a good idea to check for firmware updates to your router as new exploits and vulnerabilities arise. Some routers will have an auto update feature and it’s important to use it. Using auto update will help keep your wifi network secure without the need of remembering to check for updates.

Data Recovery Over Hard Disk Failure

by: Muneer Mohammad

Hard Disk: An Introduction

Hard Disks are used to store information. All information on computers are stored in files. Hard disks store the majority of information on today's modern computer. Hard disk drives (HDDs) can be critically damaged by static electricity, shock, and other factors, often resulting in failure or the loss of valuable data. In many cases it may become necessary to recover information from your hard drive. Such retrieval is quite possible.

Hard Disk Failure

*Physical Failures

Physical failure occurs from sudden switch off, power failure, sliding them off desks and cheap components. As for data loss, data is only magnetic impulses on the surface of a hard disk. And ridiculously small bits of magnetism at that! When the magnetic impulse fades, or changes position, trouble starts.

Drive Alignment Drift is another cause of problems. Mechanical devices are subject to wear and tear, heat and cold, loosening tolerances etc.

The small changes in the read/write heads wouldn't matter usually, as data still gets written in the same place as it will be read later. However, there is some data that hardly ever gets re-written, and that is the Sector ID Headers.

*Logical Failures

Master Boot Record Failure

Technically, when the Master Boot Record is working correctly, the master boot code scans the partition table for the active partition, finds the starting sector, loads a copy of the boot sector from the active partition into memory and then transfers control to the executable code in the boot sector. If the master boot code cannot complete these functions, the system displays a message similar to the MBR error.

*Boot Sector Failure

The boot sector is a region of a hard disk, floppy disk, and other similar data storage device. It is loaded to memory and executed as a part of the bootstrap sequence. The boot sector contains a small computer program that is loaded on the operating system into memory and transfers the control.

Most boot sector failure occurs by the defection of boot sector virus. Boot sector viruses are usually spread by infected floppy disks. In the past, these were usually bootable disks, but this is no longer the case. A floppy disk does not need to be bootable to transmit a boot virus. Any disk can cause infection if it is in the drive when the computer boots up or shuts down.

*Accidentally Deleted Data

Some time some how you may delete a file thinking we don?t need it any more, but in a week or or two you may realize that it is a needed one. It happens to the best of us, but fortunately there are ways to get these lost files back.

When it comes to data on your computer, it is almost impossible to accidentally remove it beyond recoverability. Even if you are intentionally trying to completely wipe a file from your hard drive it is exceedingly difficult.

*Cross Linked Files

A file system error that corrupts the contents of an existing file by writing data from another file into the same cluster. Running Scandisk or a similar program cleans up the problem, but one of the files is no longer usable.

*Bad Sectors

It is a portion of the Hard disk that cannot be used any more. If a part of the disk get bad sector which contains data then those data is to be recovered before use. When you format a disk, the OS will mark all the unusable sector as bad sector, however, this does not affect the overall performance of the disk as the damaged space is considered unusable.

Hard Disk Data Recovery

*Replace the (Circuit Board) PCB

Upon a Hard Drive circuit board failure, it is possible to get back the data by carefully replacing the PCB of the hard drive.

*Replace the Firmware

Hard disk firmware is the information that is used by the computer that allows it to correctly interact with the hard disk. It may be replaced or updated by the matching firmware.

*Replace the Head Stack

There are common situation that may be due to head failures. There is a small chip located in the head stack that is called PREAMPLIFIER. Working with preamplifiers always includes some difficulties, because, practically, they can not withstand static discharges. If re-soldering is needed, one should follow a number of rules to protect a preamplifier from static damage caused by careless finger touching. Although this task is very risky and it should be done in a high secured lab specially created for this task.

*Move the disk to another Drive

In some cases complete functionality of the Hard drive may be disabled while only the internal disk plate is without any damages or errors. In those situations, it is possible to move the disk to another drive.

*Spin-Stand Testers

Hard drive manufactures and their head media; preamplifier and read channel suppliers do have very accurate, very expensive "magic machines" called Spin-Stands. These are used for testing and experimenting with heads and disks. They are used mostly by researcher and development departments.

*Magnetic Force Microscopes (MFM)

Magnetic force microscopy is a powerful tool for high-resolution magnetic imaging of most data storage media. As the density of magnetic media is higher, the bit becomes smaller than the wavelength of light, so optical techniques can not resolve it. General MFM is capable of imaging the magnetic domain of several tens of nanometers. Also, MFM is almost simultaneous with measuring the surface characteristics of topography and roughness of the same area with sub-angstrom vertical resolution.

Recovery Softwares

*SpinRite 6.0

SpinRite is a stand-alone DOS program designed to refurbish hard drives, floppy disks and recover data from marginally or completely unreadable hard drives and floppy disks and from partitions and folders which have become unreadable.

*Ontrack data recovery software

Ontrack Data Recovery offers the industry's highest quality and cost-effective do-it-yourself data recovery software solutions for almost any data loss situation covering servers, desktops or laptops for all media, operating systems and file types. Ontrack's EasyRecoveryTM family of products is unmatched in its ability to recover/repair from all causes of lost data.

*Recover My Files

Recover My Files data recovery software will easily recover deleted files emptied from the Windows Recycle Bin, or lost due to the format or corruption of a hard drive, virus or Trojan infection, and unexpected system shutdown or software failure.

Software Backup For Everyone

by: John Ugoshowa

Backing up your data with almost any electrical device is crucial to keep things intact. No computer or other electronic device is crash proof, problems can occur at any time. All computers can crash at any given time, which normally results in the loss of all data that was stored on the hard drive.

The potential for less is the ideal reason to create a backup of your software and data. How often or how much you need to backup things however, all depends on how you use your computer. If your data is very important or if you use your computer for work, you may need to create a backup of your software on a daily basis, possibly even hourly for some people.

You can use various devices and equipment to backup your data, such as DVD and CD burners, tapes, external hard drives, servers on the Internet, and so on and so forth. Although each one has pros and cons, you should always use more than one backup method if your data is extremely important to you, just to be on the safe side.

When it comes to backing up your data using software, there are five different methods you can use:

1. Full backup - A full backup will create a mirror of your hard drive, every file and folder that you currently have on your computer.

2. Differential backup - A differential backup creates the backup only for files that have been changed or upgraded.

3. Disk image - This will give you the choice of backing up your entire hard drive or just the files that you select.

4. Unattended backup - Using this method, you can set the software that will create the backup to do all of the work, even if you aren’t around.

5. Snapshot backup - A snapshot backup will mirror your hard drive, backing up the images of your files.

When you decide to get a software program to assist you with backing up your files, you should always get a program that best fits your needs. Price is also an important factor, although ease of use and overall reliability should always be the most important factors when it comes to your data.

Most programs are easy to use, so even if you have never backed up your data before, you’ll be able to do it without any problems. All you’ll need to do is load the software then follow the instructions that come up on the screen.

All in all, software backup is the best way to keep your data preserved and ready. Something can happen to your computer at any given time, which is why you should always be on the safe side and back up your data every chance you get.

Data Protection: Why and How

by: Paul Abbey

The advent of world-spanning computer technologies has created an environment in which all sorts of data is easily accessible by almost anyone. At the same time, more and more of our personal data is being collected and stored in computer systems. How can we be sure that it's safe? Data protection systems and technologies exist to protect our privacy.

Data protection is geared towards protecting personal information such as family details and medical records - information we may not want to share with just anyone. Data protection schemes aim to guarantee everyone a basic minimum of privacy in line with the Universal Declaration of Human Rights. People dealing with sensitive government or corporate information may also rely on data protection.

Data protection begins with the type of privacy agreements which you will often see when you're asked to enter personal information into a website. This is the first stage of data protection - communication, ensuring that all those who are party to information exchange agree on what constitutes private data. Protection of such information can't otherwise be assumed, as the rules on what ought to fall under data protection schemes differ in different countries and between different organisations.

Whenever sensitive information is stored on computer systems, the law demands that it must be subject to adequate data protection. Special data protection software has been developed for this purpose, designed to identify this information and keep it separate from other records. Data protection depends on good information management, limiting access and, in some cases, limiting the period for which information is stored. Data protection software may also limit the context in which sensitive information can be utilised.

The advent of secure data protection systems minimises the risk of identity fraud faced by computer users sharing personal information. Data protection is essential in ensuring that emerging technologies do not undermine the older systems on which society is based.

How To Change Your Computer's Heat Sink

by: Otis Cooper

Everyone really want a fast hot computer when we want to do some business computing and when we want to play those high speed games.But we don't want a fast and Hot computer in the literal sense.

Heat will destroy any computer component if not removed in time.And the CPU Chip is one of the main components of your system that produces heat.

The heat sink has the all important task of keeping the CPU Chip cool so it does not overheat.And there may be times when the heat sink will fail to perform its job and must be changed.

Changing the heat sink on your central processing unit or CPU chip is a simple job.And the best part is that you only need a small screwdriver,cotton swabs,and some rubbing alcohol.

To change the heat sink remember to think safety first.This means that you want to be sure you have clean hands,a clean work place,and removing all static charge from your body by touching a door knob or any other metal object.

Once you have a suitable work area and clean hands you should now have a clean suitable mind as well. Allow this task to be both educational and fun.To change the heat sink perform the following.

Step 1.Unplug the computer and remove the cover from the System Unit case.

Step 2. Find the CPU Chip and the heat sink will be on top.Find the wires that go to the motherboard and very carefully unplug them.

Step 3. Remove the old heat sink and cooling fan assembly.Most Pentium based computers will have two levers that lock the heat sink in place.

On older Pentium computers,the AMD Athlon and the Duron processor,look for a ZIF or Zero Insertion Force socket where the processor is mounted.

Gently release the clips by sliding a very small screwdriver blade underneath it and lift the heat sink off the CPU.Take great care here do you don't damage the cpu chip in any way.

Step 4. Once the old heat sink has been removed, clean away the old thermal paste using cotton swabs and rubbing alcohol.Allow time for the CPU to dry.

Step 5. Grab some thermal paste and squeeze a little onto the top of the CPU.Only place enough to have a thin layer between the CPU and Heat Sink.

Step 6. Before installing the new heat sink, clean the bottom off with some warm, soapy water. Check to be sure the Heat Sink is dry before installing it.

Step 7. Carefully line it up over the ZIF socket and processor if so equipped.If the computer have the newer Pentium or Athlon based chip,lock the two clips holding the assembly.

Step 8. With the CPU and heat sink firmly in place, now its time to re-connect the fan wires for the cooling fan.Plug the assembly into the motherboard.

Step 9. Check,double check,and after that,check some more to be sure all connections are in place.See if the heat sink assembly is well secured in its socket.

Step 10. Now replace the system unit cover,plug any peripherals you disconnected.Start the PC and the computer should now realize it has a new device in its system.

Once the computer has been booted up,check to be sure the Operating System is working.If possible, look at rear of the computer to see if the fan is operating as it should.

The Central Processing Unit is not the only heat producing component in your computer.But since its the brains of any computer,you want to be sure the heat sink performs at its best.

Take the time to learn this procedure in detail by removing the case and looking at the heat sink in your own computer.Knowing how to perform this task can save you money should you need to change your heat sink in the future.

Try Out a Registry Cleaner - Speed Up Your System

by: Arvind Singh

Registry cleaners are made to make the system run faster and error free. These cleaners are available for free download from the Internet. So why not make the most of the system?

Windows operating system has a database repository for all information pertaining to a computers configuration. This information will include the data regarding the hardware and the software of the system. It will also include information regarding the users and what permissions they have on the system. The system registry keeps on growing automatically as programs are added and deleted. As the registry keeps growing it gets loaded with unnecessary information and data. This gradually clutters and fragments the registry over time. The constant growth of the registry can also degrade the performance of the PC and cause the system to crash. A good registry cleaner will defrag the registry and make it more compact by cleaning the registry of all the redundant entries that are slowing the system down.

Registry Cleaners Are a Must Have

Many registry cleaner software such as windows XP registry cleaner, windows free registry cleaner, PC registry cleaner and the like Scan the system registry and locate the obsolete information that is clogging and slowing down the system. This information can include broken links and redundant programs that serve no purpose to the system at all. The registry cleaners try to fix these broken links by locating the programs that can be associated with them or if the programs are already associated then the registry cleaner will delete the broken link altogether. This frees up space in the registry and leaves spaces that need to be filled by bringing the registry entries closer together. This is called compressing the registry. The purpose of a registry cleaner is to make the system run faster and error free. Most of the registry cleaners achieve this with ease.

Backup Function Is Most Important

Registry cleaners have a registry backup function that needs to be run before cleaning up the registry. This is because the registry is the backbone of the system and in case anything goes wrong at least the system can be restored to its previous working level. Many registry cleaners and registry repair software have a startup management tool built in. This permits the user to select the programs that start up automatically when the system boots. Though this can be achieved by typing the famous MSCONFIG command at the RUN dialogue box the registry tools keep you up-to-date with the programs that are in the startup of the system every time you run the registry cleaner on your system.

So to cut a long story short it is sufficient to say that PC users have found that the use of Registry Cleaners is a boon to the PC. The registry cleaner software keeps the system running fast and efficiently all the time. The only job left for the user to do is to manually run the Registry cleaner from time to time.

What Is an ActiveX Control And How Is It Related With The Registry ?

by: Arvind Singh

ActiveX is a technology that was developed by Microsoft to enhance the display of images, video and animation in their browsers. ActiveX components are a set of rules that guide the browser to display hi-resolution images and streaming video properly.

It should suffice to say that ActiveX is a technology that was developed to bring the power of Object Linking and Embedding or OLE as it is popularly known, to empower web browsers and particularly Internet Explorer, to display such objects. When web pages with embedded ActiveX components are downloaded, the corresponding controls are also downloaded and automatically launched by the operating system of the computer. This can, over some time, clutter up the registry with unwanted data and controls, thus slowing down the system drastically. This will mean having to clean up the registry with a registry cleaner periodically. ActiveX controls are actually used by windows to display very rich interfacing activity such as animation, video images, virtual reality that used 3D technology, high resolution images and the like.

ActiveX Prompts For Registry Cleaners

When downloaded into your computer, an ActiveX control is actually packaged as an .OCX file. There are cases when more .OCX files are downloaded and needed for a web page. The .OCX files like ActiveX controls need to be registered on your system before they can be used. Registering means that a program capable of doing this, queries the ActiveX control and saves specific information about it into Windows Registry, so that the operating system can find it and therefore be able to use the ActiveX control. However, one must keep in mind the importance or cleaning up the registry periodically. The Internet has the best registry cleaners available free. So, make use of them to keep your system running smoothly.

Pro's and Con's Of ActiveX Controls

It is important to understand that with all the 'pros' of ActiveX technology also come a few 'cons' as well. ActiveX is a very powerful tool and is sometimes used by individuals, with a flair for the technology, to create ActiveX controls with malicious intentions. These 'corrupt' ActiveX controls can wreck havoc on your system and leave you helpless for no fault of yours. After all, you know that ActiveX is supposed to help your system run some programs, right. So why not download an ActiveX control when you are prompted to do so? It is for this reason that Microsoft has developed the ActiveX security system.

In Windows XP operating system, this security system is embedded in the Internet Explorer. The registry of the system automatically blocks the download and installation of any ActiveX component in the Registry of the computer. Apart from this is an ActiveX component has to be installed the computer will prompt the user to check for the signature of the component. If the ActiveX component is registered with Microsoft the ActiveX is verified as authorized and is allowed to be installed in the registry of the computer. If the ActiveX component is not verified the systems offers the user a choice of not installing the ActiveX control.

Some Advise For Internet Explorer Users

If you are using Internet Explorer you should ensure that you are using a security level set to Medium or above in Internet Explorer. You can do this by going to tools in IE and select 'internet options' then click on 'security' and slide the level to medium or higher. Now, after reading about the entire automatic downloads of controls and stuff, it makes sense to download a free window registry cleaner and use it periodically to clean the registry of your system. There are enhanced registry XP cleaners to clean the complex registry of Windows XP as well.

What Is A Shortcut And How Does It Work?

by: Arvind Singh

A shortcut may be a link that you have created somewhere, usually on the desktop, or may be a combination of keys to launch a program. Shortcuts will all be registered in the registry and clutter it up as and when you keep on adding the shortcuts to the computer. The registry thus needs to be cleaned up regularly with a registry cleaner.

There are two types of shortcuts in windows operating system environment. On shortcut is a link created and placed anywhere. This is mainly placed where one can see it such as on the desktop. Right clicking on the desktop and selecting -New - Shortcut can create a shortcut link on the desktop. Then browsing through the next window to get to the file or program that you want to create a shortcut link on the desktop to.

Once you have selected the object for the shortcut you click finish and a link is created on the desktop. Clicking on this link will open the file. Another way is to navigate or browse to the file or program on the PC and right click and select 'create shortcut'. The system will warn you that the short cut will be placed on the desktop for the particular object. Clicking 'ok' will accomplish the task. Now that you know what a shortcut is and how it works, you should also know the impact it may have on the registry of the system and why the registry has to be cleaned with a registry cleaner from time to time.

Some shortcuts can be created with the help of the windows keyboard. Presetting a set of control Alt (Key) will start up a program without you having to navigate to where the program is stored to get it up and running. However these shortcuts will all be registered in the registry and clutter it up as and when you keep on adding the shortcuts to the computer.

The registry is a central database of all the activity on the system and needs to be cleaned up regularly with a registry cleaner because as the registry grows older and is used more often it slows. When a shortcut key is pressed the shortcut keys refer to the registry for information on where to locate the program or file to launch. The registry in turn goes through its entire database in the section to locate the data being queried. So, if the registry is large with useless shortcuts, it will take a very long time to locate the shortcut that is being sought. This is the reason that the registry must be cleaned with a windows registry cleaner on a regular basis.

There are many free windows registry cleaners on the Internet. So go on and make your choice. It can only be of help to speeding up the system and making the operating system run error free and more efficiently with as few headaches as possible.

How To Avoid Spyware

by: Arvind Singh

Spyware can install itself into your system when you clicked some link to a program, opened spam email, clicked on certain popup windows or if you were downloading some free utilities, toolbars or games. Protect yourself with antispyware software. And check to see if your security settings are too low, change the settings to default level or higher, and keep a check on what you download.

Spyware is so invasive that Antispyware programs rank high on everyone's list of favorites when it comes to keeping the computer healthy and running. While no one's safe from spyware, there are some things you can do to avoid spyware, in addition to having antispyware solutions installed.

The most irritating thing about spyware is how it got into your system in the first place, not to mention how long it's been there or what it is doing. What could have triggered its existence in your system? What is even more annoying is the fact that you probably got tricked into clicking a link to some program for it to get installed in your system! Maybe you opened spam email - sometimes that's all it takes.

If you click on certain popup windows or if you were downloading some free utilities, toolbars or games, there's a pretty good chance it sneaked in that way, unless you had antispyware solutions installed in your system. The most likely source are those file sharing programs that are rife with spyware. And if you happened to browse through a corrupt website, it is no mystery at all as to how the spyware came in. Some legitimate software applications come bundled with the spyware.

Be Careful About Those Freebies

The Internet is full of free software that tempts you and when you succumb to it, comes integrated with spyware. If you are not protected by antispyware software, this spyware will relay all your browsing habits to spurious advertisers. Even your sensitive personal data can be revealed. How do you prevent this from happening? The first step is obviously to install antispyware software.

Exercising Caution

Beware when you surf the Internet. Check to see if your security settings are too low. If your system is not protected with antispyware software, this low security setting is a fine entry point for tracking cookies and spyware programs so that they can lodge themselves in your system. So, first change the settings to default level or higher, preferably, and keep a track of what you download. Update your operating system regularly. And keep your antispyware application also up to date with new definitions. Your antispyware solution will detect, then quarantine and delete spyware that happens to enter your system by chance.

Watch your email! If you don't recognize the sender, don't open the email or click anything in it. Only open email or download programs from sites you trust. Nothing comes free. Check around the online forums about which software comes bundled with spyware. It is easy to get feedback off the Internet about spyware and which antispyware is best to combat it.

How To Maintain Your Privacy Online

by: John Pachecus

Nobody wants their private information all over the internet. If a hacker gets a hold of some of your personal information, it can ruin your life. Did you know that many websites collect your personal information without your permission and without you even knowing it?

They collect this information for a variety of reasons. They like to get information and send you spam, adware, and junk mail. Sometimes hackers can get this personal information and use it for identity theft or to infiltrate your computer. But I know you are wondering “how do they get my private information through the Internet?”

It is actually quite easy. First of all, every computer has an IP address. When you visit someone’s website, the website owner can track you through your IP address. All IP addresses are logged into the website’s server. You IP address can give away details many private details like, where you live.

It can be quite a scary thought, but there is a solution. The solution is an anonymous proxy server. So, what is an anonymous proxy server? An anonymous proxy server is a machine that is between your computer and the server you are accessing to view the web page you want to look at. They provide the best privacy and hide your IP address so you can surf anonymously and securely. No one will even be able to tell that you are using an anonymous proxy server! is one of the best tools for hiding your identity from online scammers. It is your guide to private online surfing. They have a huge list of fresh proxy servers. The best thing about is that they are 100% free and that they are always up to date. Being updated frequently is very important because eventually all proxies get blocked.

Used Computers (Desktops/Laptops)– What To Look For?

by: Christophe Catesson

Nowadays desktops and laptops are much more durable and dependable that they were just five years ago. Therefore, buying a used or refurbished computer is becoming more of a trend.

Suppliers replace their computers on average every 6 months and companies frequently upgrade their equipment. Buying one of these used or refurbished computers can save you a lot of money while still using a quite up to date technology. This is even more relevant if you are not a heavy user (i.e. most of your time on a computer is spent online, you may use a few standard applications once in a while). Even modestly priced computers will more than suffice for these types of demand.

Thinking about buying a used or refurbished desktop or laptop?

Buying a computer is not at all an easy job, one has look get detailed information of the available computers of good and reputed brands. One must take into consideration the size, color, configurations, features etc… While your computer should correspond to your personality and lifestyle, you should always keep in mind the reputation of the brand in the market. Brand counts a lot; you can render good service by the manufacturer if your computer is damaged.

Important handy Tips before buying a computer...

* Verify if the brand is reputed and always buy a good reputed brand. Read about customer service experience for that specific computer issues
* Check the warranty/guarantee of the computer (seek out computers which still have warranty/guarantee remaining)
* Compare the price of the new model in the market with what price your buying your used computer, try to get the best bargain. i.e. a two year old computer should not be bought for more than half of its original price.
* Check if the computer is outdated (if out of production it is difficult to get spare parts)
* Is the operating system current (Windows Vista/Windows Xp). Earlier versions probably run slower (windows 2000) and would not be advisable unless your needs are limited (i.e. web surfing, Word...). In any event, stay away with computers running on Windows 98 (granted you don't find many anymore). Also be aware of Windows Vista. Many users are reverting back to XP and that is even more obvious in the corporate world. Why? Vista looks nice but doesn't bring many technical improvements; therefore IT managers are not willing to implement something new when what they have works just fine. Some domestic users just don't like the new way of navigation within the Vista Operating System.
* Check if the configuration of the computer you are buying is good.
* Check the speed of the processor. If possible start the computer and see how long it takes to fully turn on. If its slow just turning on, imagine the lack of speed once you start adding software..

Additional Tips for laptops

* Is the battery life good? (search for the computers with a very good battery backup (2 hours minimum).
* Check for the screen size of the computer your buying and see to it that it is not exceeding the Normal (normally the screen size should be between 15-17). Less than that generally translates in older computers and increases the chance of age failure. Once the screen breaks, you are often better of changing the whole computer.
* Review the connectivity of the computer (Network, USB, Video, Audio…) look to it that it has a good connectivity including wireless
* Check out the weight. Ensure the computer is light enough for you to carry (light 7pounds)

Where to buy used computers:

* Online auctions. Pro: Often offer the best prices. Cons: Cannot validate the accuracy of the described item. No warranty. Tip 1: Some companies will offer warranty for up to two years, the cost is about 12 of the purchase price. Tip2: Buy from sellers with great feedback, do not hesitate to contact the seller with questions prior to bidding
* Online marketplaces: Pro: Set prices and quantities - Sometime warranty is available. Cons: Prices can vary a lot, do your homework
* Contacting sellers on in your local area gives you a chance to meet with the owner and physically test the computer before the purchase

Where to buy refurbished computers:

Refurbished computers can be a great way to buy as they have warranties and are generally sold by manufacturers or companies affiliated with them.

* Manufacturers websites will tell you how to buy directly from them or from their authorized sellers. Pros: Warranty, established companies. Cons: Prices are higher than regular auctions (you pay more for peace of mind)

Buying a used or refurbished computer can be a great way to save money. If you use some of the advice discussed above you can avoid many pitfalls. One last thing concerning laptops, make sure you have a good bag to protect your computer from a fatal accident. Your bag should be big enough for a 17 inch screen computer as it is rapidly becoming the norm, you will probably change your computer within a few years, the bag you may keep a lot longer.

Good Buy!

What Is Internet Fax?

by: Titus Hoskins

Internet Fax is simply using the Internet or your email system to send and receive faxes. Since it is web based, you can send your faxes anytime anywhere; as long as you have an Internet connection and these days that's available just about everywhere.

You sign up with an Internet fax service provider to get your own fax number (local or toll free) which you use in the same manner as you would use any fax number. There is a small charge for this service but keep in mind you do not need an extra phone line to do Internet faxing since everything is done online.

Many small and large business owners are switching over to Internet Fax for some obvious advantages: it is very convenient, it is very fast, it offers more privacy, many faxes can be sent/received simultaneously (no busy signals) and it is available wherever you have the Internet. Plus there are no messy fax machines and no need for a second phone line.

One of the most asked questions about Internet Fax relates to the confusion over just how the whole thing works. Many traditional fax users can't quite get their heads around the idea of having faxes without the traditional fax machine.

Basically, you sign up with a fax service provider and get your own fax number and you send/receive your faxes thru your email system - your fax is attached to an email as either a TIFF or PDF format file. You can access your faxes from an online interface (your fax login site) where your faxes are received and sent. You can also store your faxes online there.

What confuses most people who are not familiar with online faxing is the question: can I still send my faxes to the old traditional machines, since many of my business partners may not be using Internet Fax?

The answer is YES!

You can send your faxes to the old traditional fax machine and if they have your fax number, they can still return a fax to you via the old traditional manner or fax machine.

Here's how Internet Fax works:

You use a fax gateway or Internet Fax provider/server to handle your faxes. For example, say if you were sending a fax.

Computer/Internet -> Fax provider/server -> Phone line -> Fax machine

You use your computer and the Internet to log into your online account/page to send your fax to your fax provider/server which then uses the phone line to send your fax to the receiving fax machine.

If you are receiving a Fax

Fax machine -> Phone line -> Fax provider/server -> Email message (thru Internet) -> Your Email account

Someone uses a fax machine to send you a fax which goes thru the phone line to your fax provider/server which converts it into a TIFF or PDF file and sends you an email message with your fax attached in your email.

If both parties are using Internet Fax, then your faxes can be sent/received using your email systems over the Internet.

Computer/email -> Fax provider/server -> Computer/email

What you really have to keep in mind, once you sign up for an Internet fax service you will have an online interface (login site) where you can send and receive your faxes. Then when you send or receive a fax, you get a confirmation in your web interface and/or by email.

This offers some great advantages such as receiving and sending your faxes whenever and wherever you access the Internet. No more busy signals, no more messy fax machines, no more nosy workers seeing the contents of your fax, and no extra phone line. Plus, many faxes can be sent/received simultaneously, even when your computer is turned off. No more missed faxes because your phone line was busy.

However, in order to get all these advantages you have to sign up for an Internet fax service. There are many well known Internet fax providers such as MyFax, eFax, RapidFax, TrustFax, Send2Fax... and some very good lesser known faxing companies such as MetroHiSpeed out of Seattle and Faxage out of Denver.

A word of caution, when signing up for any long term business service it pays to do your homework first. It pays to shop around mainly because even any small savings may prove significant over the long haul. Prices can range from very cheat (under $20 a year) to around $10 - $15 a month depending on the kind of service you need. There are many different plans and services, and keep in mind, you will pay more for International faxing.

Internet Fax seems to be the way of the future as more and more businesses go online. Besides, as we become more and more modernized, computers are offering us simple and convenient solutions to many of our daily traditional business tasks such as faxing. Can your business or any company really afford to be left behind or not take advantage of the benefits of Internet Fax? Can you still remain competitive without Internet Fax? It's your call?

10 Easy ways to improve Windows XP performance.

1.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system. The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature,
I recommend disabling it.

1.1) double-click the My Computer icon.
1.2) right-click on the C: Drive, then select Properties.
1.3) Uncheck "Allow Indexing Service to index this disk for fast file searching." and click Apply button
1.4) Check at "Apply change to C:\, subfolders and files" and click OK.
If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

2.) Once a month, run a disk cleanup. Here's how:

2.1 Double-click the My Computer icon.
2.2 Then right-click on the C: drive and select Properties.
2.3 Click the Disk Cleanup button
2.4 Check at Temporary files and click OK.

3.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

4.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

5.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations.
Windows XP offers many different settings in this area. Here's how to do it:

5.1 Click Start button , Setting and Control Panel
5.2 Double click on System icon
5.3 Click on the Advanced tab. and Select the Settings button located under Performance.
5.4 Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

6.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

7.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

8.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead.
For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

9.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

10.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly.

Protecting Children Online With Internet Parental Controls

by: Kelly Hunter

The World Wide Web is a fascinating place. It has obliterated geography in terms of education and business. It facilitates learning by allowing kids to see things and experiences aspects of different places they may never get the chance to see in the non-virtual world. The Internet can bring people together who otherwise would never know each other and create a virtual universe that is totally cohesive, with every kind of information imaginable literally available at your fingertips. Sounds great, doesn’t it?

Unfortunately, the Internet has a dark side. It is full of material that is inappropriate for children and all kinds of predators. Leaving your kids alone to fend for themselves on the Web is exactly as dangerous at leaving them in a crowed airport or shopping mall. You don’t know where they’re going or who with. The news is filled with horror stories about kids who have been taken advantage of on the Internet, but you don’t want yours to miss out on all the positive aspects of the technology. The first line of defense in keeping your kids save on the Web is to teach them how to use it safely.

A lot of online dangers can be dodged simply by reminding kids of one of their earliest learned lessons: don’t talk to strangers. The kinds of people who want to harm kids have all kinds of tricks up their sleeves. They may try to lull your child into a false sense of security by pretending to be someone she knows. Make sure your child understands that it isn’t a good idea to give out personal information such as their address, phone number or the name of their school. The less information a potential predator has, the harder it will be for him to actually locate a victim. It might be a good idea to establish a secret password and share it only with friends and family so your kid has a way to identify people who are safe to chat with.

Chat interfaces and instant messaging are great tools for keeping in touch with friends and conduct business, but they are also direct connections between your child and possible pedophiles and other predators. Most instant messengers have settings that will only allow people on a pre-approved list to approach your child. That way you can let the kids chat with family and friends while keeping the bad guys out. You can visit

to find more information on online child safety measures.

You can’t watch your kids every minute they are online, and you can’t always count on them to do what you have taught them to do. Parental control software is a great back up. Most browsers will allow you to customize age-appropriate settings for each child in your house. You can choose what kinds of Web sites you want your kids to access and block them out of the ones you don’t. It’s a great way to provide a virtual safety net for your family. If the parental controls supplied by your Internet Service Provider, check into installing additional software that will evaluate each site your child attempts to access. You set criteria by which the software judges each Web page and assigns a rating, much like a movie rating. Your kids will only be able to look at sites with ratings you have deemed appropriate.

Where To Get Free Help

Virus Protection

There are two main steps to protecting your computer from viruses, Trojans and worms:

1. Install AntiVirus softwareYou can purchase a copy of AntiVirus software and install it on your computer. If you do not have any such software installed on your computer - this should be the next item you buy! AntiVirus software protects you from becoming infected by regularly scanning all files on your computer for viruses, and in most cases by checking every single file that you access (including files received via email etc) for viruses.

2. Keep it up to dateNew viruses appear all the time. There are at least 57,000 different viruses and more being created every single day! AntiVirus software can normally only detect those viruses, which the developer of the AntiVirus software knows about. Therefore it is absolutely essential that you keep your AntiVirus software up to date. Most AntiVirus software vendors provide a service (often for free) where you can get updates to the software. These updates allow you to detect and eliminate new virus threats. In some cases, AntiVirus software can even update itself over the Internet automatically! Always update your AntiVirus software as often possible - preferably every week.

Extra Security

Here are some additional steps you can take to protect yourself from viruses:

1. Get some Backup Software and take regular backups of your data. Ideally on to a location this is not on your computer. For example: a ZIP disk, Writable CD, etc. This way, if a virus infects your system (or another problem occurs) and you can not recover, you can always go back to the previous version of your data.

Do not overwrite your previous backup when taking a new backup. Problems have been known to occur during the backup process, so you want to make sure that you always have one complete backup available.

2. Do not open email attachments unless you were expecting to receive an email attachment from the person who sent the message. This includes email attachments from people you know - their computer may be infected, and the virus may be sending you email without their knowledge.

If you are not sure if the sender meant to send you an attachment, write to them and ask if they knew they sent you an an attachment and if they know what is in it.

When writing to a person who sent you a suspect attachment, be sure to use "New Message" (or the equivalent function) in your email program. Do not click "Reply" as you may easily inadvertently open the virus infected file.

3. If prompted, do not run macros when opening Microsoft Word or Excel documents unless you put the macros there yourself. This is especially true for documents received via email, even from people you know.

4. When downloading files from Internet sites save the files to a temporary folder on your computer, or to a floppy disk etc. Scan them for viruses using your AntiVirus software before opening or running them.

5. Avoid downloading files from disreputable sites. For example, do not download files from "crackz", "appz",. "warez" or other illegal/pirated software sites. Such files have been known to contain viruses, Trojans, etc.

6. Check that there is not a floppy disk inadvertently left in the drive before rebooting or restarting your computer.

If you start your computer and there is an infected disk in the drive, you can catch a virus this way!

7. Prepare a clean MS-DOS boot disk, and keep it in a safe place.

On most computers you can can make such a disk by opening an MS-DOS window and typing:


After preparing the disk, set the tab on the floppy disk to the Write-Protected position.

You may need this disk when recovering from some types of virus infections. Your AntiVirus software and/or AntiVirus web sites contain instructions for cleaning up viruses.

8. If possible you should also familiarize yourself with at least the basic MS-DOS commands. Knowing these commands can prove extremely handy in an emergency situation (and can also help you use your computer more productively).

AntiVirus Software

There is a wide choice of AntiVirus Software available.
Regardless of which program you choose, always update your AntiVirus software as often possible so as to protect yourself from new virus threats!

- Norton AntiVirus
This program scans your disk for viruses, performs a live check on files accessed and is very regularly updated (there is even a function to update your AntiVirus protection over the Internet).

There are several versions to choose from depending on which version of Windows you have on your computer, and which media (CD-ROM or download) you prefer. I recommend the your purchase the Professional Edition which has more functions and is more powerful.

Other popular AntiVirus programs include:
- McAfee Virus Scan
- Panda AntiVirus


These web sites contain enyclopedias of information about viruses:

I particularly recommend the following web sites which, in my opinion, are the most comprehensive and regularly updated:

- Symantec AntiVirus Search for Viruses
Comprehensive searchable directory by Symantec who are the makers of the Norton AntiVirus software.

- McAfee Virus Information
Another excellent encyclopedia with good descriptions of common viruses.

What Is A Virus

A virus is computer code, which makes copies of itself, without the computer user's (victim's) knowledge. Viruses attach themselves to other files or programs on the victim's computer - and often take complicated steps to disguise their presence.

- Some viruses are deliberately harmful or malicious - they carry a "payload". For example, erasing data from the victim's hard-disk.

- Other viruses simply attempt to make copies of themselves. Even these viruses can beharmful as they often have unintended consequences, and they always use computer resources (example: disk-space) without the computer user's knowledge or consent.

Very often, a virus can lay dormant for a long period of time (or until a given date), sometimes even years, before copying itself or executing its payload.

Viruses are usually designed by the virus writer to attack a particular type of computer or software. Most viruses are targeted at (and therefore can only infect) users of Microsoft operating systems (MS-DOS and Microsoft Windows) and/or Microsoft products (Microsoft Word, Microsoft Excel, Microsoft Outlook Express, etc.). However there are also viruses which affect other types of computers and software

How Viruses Spread

If a virus just stayed on the infected computer and didn't spread to other computers it wouldn't be too much of a problem (except for the unlucky victim). However just as a virus can infect the files on one computer, it can easily spread on to other computers:

-Some viruses attach themselves to program files (which may include EXE files, device drivers, etc). When the file is copied (or emailed) to another computer - it ends up being infected.

-Some viruses attach themselves to document files (most often Microsoft Word or Excel documents). These "macro viruses" use the advanced features of Word, Excel etc. to replicate themselves.

-Some viruses reside in the boot-sector of floppy or hard-disks. The boot sector is a special area of the disk, which is read and executed when the computer is started. If a computer is started with an infected floppy disk in the drive, it becomes infected.

-Some viruses send email from one computer to another, usually without the sender's knowledge. For example, these emails may be sent to people in the victim's address book or whose email address was listed on recently visited web pages. These viruses send an infected attachment with a plausible looking message. When the recipient opens the attachment, their computer becomes infected.

-Some viruses combine more than one of the above strategies and may switch between different strategies at different times or under different circumstances.

Virus Hoaxes

If you have been on the Internet for a while, you have probably received hoax virus warnings. (If you are new to the Internet, don't worry you are bound to get one sooner or later!) Hoax virus warnings are started by a person maliciously (or as a prank), but then passed on by many innocent computer users who wrongly believe they are genuine warnings and that they are helping others by passing on these messages. Most hoax virus warnings instruct the recipient to forward the warning to "everyone you know" and this is why they spread so fast. (Incidentally many people are taken-in by, and pass on other fake/hoax messages, including "opportunities", "news" or "secret information" )

If you get a virus warning or message telling you to pass it on to "everyone you
know", chances are that it's a bogus message. The most well-known virus hoax is
"Good Times".

Hoax warnings are not harmless.

- It has been known for a company's email system to be crashed by the volume of email generated by users forwarding warnings to everybody else repeatedly!

- Hoaxes waste user's time, as well as Internet resources and bandwidth.

- Some hoax virus warnings encourage users to delete files from their computers - for example - files which are not infected with any virus and may be essential to the correct operation of the computer.

-We recommend that you do not pass on virus warnings at all. If you must do then check carefully whether the warning is a hoax first! Companies should establish a clear policy that says virus warnings should not be passed on, or passed only to the IT department (which can then determine the veracity of the report) and not to all users.

Trojan Horses

The name Trojan horse comes from Homer's Illiad in which Greek warriors were able to sneak inside the walls of Troy (which they were besieging) by concealing hemselves inside a "gift" of a wooden horse.

In the computer world, a Trojan horse (often called just "Trojan") is a program (or occasionally a document) which appears to be harmless, or even useful, but actually has a malicious intent such as erasing the victim's hard-drive.

The difference between a Trojan and a virus is that:

- A virus copies itself without the user's knowledge

- A Trojan is copied by users deliberately - although of course they don't know about its hidden malicious intent. Sometimes Trojans are attached to illegal copyright violating software ("pirated software", "appz", "crackz", etc.).


Like a virus, a worm is a program that spreads itself from computer to computer without the victim's knowledge. Also, like a virus, worms may sometimes have deliberately malicious effects, although in many cases the mere fact of replication can be enough to be harmful to computers or networks. The difference between a virus and a worm is a technical one:

- A virus attaches itself to files (programs or data) on the victim's disk and spreads when these files are copied or executed.

- A worm resides in the computer's active memory and spreads from one computer to another by infecting other computers over a network connection (these days most often the network is the Internet).

Because worms use network connections to spread themselves, they can spread incredibly fast and generate massive amounts of network traffic (slowing or blocking legitimate access to the network).

Another worm in the news (July 2001) is the "CodeRed Worm" which affects Windows NT and Windows 2000 web servers. This worm takes control of infected servers and then uses them to launch "Denial Of Service" attacks against the other Internet sites. This worm has been highlighted in the press by US government officials and Microsoft. Microsoft have also made a fix available for the security hole that this worm exploits


Although there are distinct definitions of the terms "virus", "worm", and "Trojan", virus-authors do not always follow these definitions.

In fact, it is quite common for viruses to combine attributes of each of these types of programs. For example, the virus Happy99 spreads itself by creating a Trojan called HAPPY99.EXE or HAPPY00.EXE and emailing this Trojan to unsuspecting users.
