I'm sure all of you have hard this before: ANTIVIRUS IS A MUST HAVE FOR ANY PERSONAL COMPUTER IN TODAY'S WORLD. But before I tell you why to have an antivirus installed on your computer, let me explain what a "virus" is, more or less. A true computer virus is much like any sort of virus in the real world. It has the ability to copy and distribute itself across a computer's file system to cause irreparable harm to the entire system itself. The term "virus" is used synonymously with basically any form of malware on today's market. Examples are trojans, worms, true viruses, or spyware.
Antiviruses today are a dime-a-dozen. Every where you turn, there's antiviruses everywhere! There's a basic one that comes with Windows OS, there's other that you can buy at the store, and there are even a couple 100% free ones floating around the internet. Having one is easy, you don't need to have a $100-a-year antivirus to "stay protected". Simply having a free antivirus like AVG is 8/10 times enough to stay secure. Also having an expensive one like "Norton Internet Security Essentials" is probably about 9/10 times enough to stay secure. The simple fact-of-the matter is having some sort of Antivirus.
Oh, and yes, Apple Mac OS have viruses now. Don't be one of THOSE people who think they're 100% secure because they have a Mac.
