A virus normally requires an action to infect a victim. For instance, the malicious programs inside e-mail attachments usually only strike if you open them. The effect of a virus can be anything from a simple prank that pops up messages to the complete destruction of programs and data.

Some viruses attack the computer’s boot sector, the area on the hard drive that hosts the code for the start-up routine. Such a root code virus causes havoc because it runs itself every time you switch on the computer. Other viruses are hidden in emails, games or attached documents. These applications will appear to run normally but in the background; the malign code plays tricks like sending infected emails to everyone in your contacts list.

Another kind of malicious agent is the worm. This is able to replicate itself, often programming the infected machine to send copies to myriad random computers. Successful worms spread almost exponentially through networks, consuming processing power and bandwidth as they go.
