Most virus authors incorporate code that specifically destroys data after the virus determines certain criteria have been met, that is, a date, or a certain number of replications. The people who make anti-virus software have much more to benefit from the creation of new virii. I admit there are many out there who create them out of malice, but far more people are just meeting a challenge in software design.

Some viruses destroy programs on computers although, the better virii do not. Viruses often have damaging side effects, sometimes intentionally, sometimes not.

Most viruses are created out of curiosity. Many viruses do not do a good job of infecting other programs and end up corrupting, or making the program they are trying to infect completely unusable. The purpose of a virus, in many cases, is to infect as many files, with little or no noticeable difference to the user. When run, a Trojan Horse does something devious to the computer system while appearing to do something useful. erting in those files' copies itself. A worm is a program that spreads itself across computers, usually by spawning copies of itself in each computer's memory. The term ‘Worm’ comes from a science-fiction. A worm might duplicate itself in one computer so often that it causes the computer to crash.
