Antivirus - What is a Computer Virus?

Before understanding what a computer virus is, it is necessary to understand what a virus in when it occurs in a living form (such as a human body, an animal, or a plant).

A virus is a small organism that is only able to reproduce itself within another living cell or body. It is typically harmful to the cell or body in which it lives, and is the cause of many illnesses and diseases. The word virus comes from Latin and literally it means "poison." So basically it is a "poison," able to reproduce itself within another cell or body. An example of an illness caused by a virus is the flu.

How does this relate to computers? Well basically, a computer virus is a harmful computer program which will damage files or your computer, and which is able to duplicate and spread itself within a computer or computer network. Usually the computer virus is hidden within a program, file or document.

Criminals, or somewhat talented idiots with nothing better to do with their time, create computer viruses and spread them to other people's computers. The sole purpose of this activity is to create trouble and damage.

Similar to a common virus like the flu (which spreads from person to person), the computer virus has the ability to spread and "infect" other computers, files or documents. A computer virus can spread itself through files and documents; such as word-processing documents, spreadsheets, emails, computer programs etc. It can spread itself through the Internet and through local computer networks, as well as through removable storage devices such as memory sticks and floppy disks. Because it is hidden, it is hard to detect. It can be spread to other computers, unknowingly, by the computer user.

What exactly does a computer virus do? Well, it works similarly to viruses (like the flu) that make a person sick. A computer virus will make your computer "sick". What a virus will do to your computer depends on what it is programmed to do. Some can be very harmful, while others are made to simply annoy.

A wide variety of names have been made up, in order to describe different types of computer viruses. Some examples are as follows (you may click on these terms for a more detailed description of what they are):

Macro Viruses

Email Viruses

Trojan Horses

Understanding the basics of what viruses are is the first step to learning what to do about them, and how to be completely in control of your computer's security. I hope this information has been of use to you.

The Importance of Anti-Virus Software

Any computer and internet user, regardless of the reasons that they are online, need to have the latest anti-virus software programs installed on their computer. Even thought most of these programs come already installed with your computer and are free, anti-virus software is absolutely essential to safe and uninterrupted internet usage. It also plays and important role in computer safety, as it can protect your vital documents and files from becoming damaged or lost forever.

How does an anti-virus software program detect and eliminate potential virus threats? This can be accomplished in one of two ways. First, the computer security program on your PC or laptop scans any files looking for virus definitions that match a virus dictionary. If a matching virus is found, the software alerts the user about the virus. The second method of locating viruses is to identify and suspicious virus behavior, such as port monitoring, spyware or data capturing. When these behaviors are detected, the anti-virus software springs into action and gets rid of the infected files.

Every so often, you'll hear on the radio or see on the news about a potential virus or worm that is spread via email. It may come with a subject line like "open this to see a funny video". Once the video is opened and downloaded, the virus infects your computer and starts eliminating or damaging files. Anti-virus software can help minimize the overall threat that viruses cause. As certain as you would lock your doors at night, or hide away valuable items in a safe location, computer safety depends on having anti-virus software installed in your machine.

There are certain free anti-virus software programs that you can trust to safely install and operate on your CPU or laptop. Programs such as McAfee and Norton are proven and respected names in the computer security industry. These companies continuously monitor and update their respective anti-virus software applications as new and more dangerous viruses are released. While the potential for completely eliminating computer viruses and their ramifications from online users is remote, having these – and other anti-virus programs on your computer can greatly reduce the risk that viruses can cause.

As with any threatening issue, there's always an element of conspiracy that's involved, and it's no different with anti-virus software companies. Think about it, if viruses were completely eliminated, then there would be no longer any need for purchased or free anti-virus software programs? Some people theorize that computer security companies actually benefit from viruses and they actually keep virus writers on their payroll! Of course, this has never been proven, but it would make for an interesting movie.

Regardless of whether or not you believe in conspiracy theories, one thing is for certain: that computer security is dependent on anti-virus software and vice-versa. New worms and programs are being developed all the time. Some viruses target specific files, like word documents or excel spreadsheets. Other more malicious programs can actually shut your computer right down. However, by installing the latest and most effective anti-virus software programs on your computer or laptop, security will increase and you'll have peace of mind as a luxury. Travel and visit some computer retailers in your area to learn more information on the newest anti-virus software programs.
