Basic Computer Virus Information

Since computers have become such an integral part of business and personal life, it makes sense for everyone to know the basics about computer viruses. This primer on computer virus information will provide you with the basic facts that you need to know about viruses, how to avoid them, and how to eliminate them.

What is a Computer Virus?

In order to understand the basics about computer viruses, you need to know what a virus is. Simply put, a virus is a computer program that has been designed to infiltrate a computer or network, where they replicate themselves to infect even more computers. While some computer viruses don’t cause any harm, others are designed to steal information or damage important files.

What Kinds of Damage Can Computer Viruses Cause?

Knowing basic computer virus information can help protect your computer from a variety of problems. Perhaps the most troubling are those that have been designed to gather private information. This can include banking information, email passwords, and other data that can lead to identity theft. Some computer viruses essentially play pranks on those who get them. They might, for instance, remove information from your hard drive or create annoying quirks in your system.

How Do Computers Get Viruses?

Computer viruses are most often contracted through email attachments. These attachments might not seem to do anything when you open them, but they have unleashed a virus that will embed itself in your computer and begin performing its intended objective.

What’s the Difference between Computer Viruses and Worms?

Computer viruses are spread through human activities such as downloading files and opening email attachments. Worms, however, can infect your computer even if you haven’t opened any files. They spread from computer to computer on their own through the Internet.

How Can I Avoid Computer Viruses?

Since computer viruses are most often spread via email attachments, you can protect yourself by following a few simple rules.

• Never open an email attachment from someone that you don’t know.
• If you receive an email with an attachment, then you should contact the sender to make sure that the attachment is safe. Many people unintentionally infect their computers by opening attachments sent from a friend’s email address. They think that these attachments are safe because they know the sender, but some viruses actually replicate themselves by infiltrating a person’s address book and sending copies to those listed.
• Scan attachments and downloads with virus protection software before you open them.
• Avoid illicit downloads. Pirated software, movies, and music often contain viruses. Even if you’re not worried about the legal repercussions of illicit downloads, you should worry about the damage that they can cause your computer.

How Can I Eliminate Computer Viruses?

This largely depends on the specific virus that your computer has, so it could require more advanced computer virus information depending on the particular virus. Still, there are some basic things that you can do to eliminate viruses from your computer.

• Update your operating system regularly. Most popular operating systems provide updates that will prevent known viruses from causing problems.
• If you know the name of the virus that has infected your computer, then search the web for a solution.
• Subscribe to a virus protection service.
