If you use a computer, the sad fact is that you need to know about computer viruses. There are many different ways to classify viruses, each with its own set of colourfully named categories. Worms, macroviruses, trojans and backdoors are some of the more well-known examples. Many of these viruses spread over the internet using email, malicious webpages or other means to infect unprotected computers.
