Worms and Viruses

Worms and viruses are rather unpleasant terms that have entered the jargon of the computer industry to descry some of the ways that computer systems can be invaded.

A worm can be defined as a program that transfers itself from computer to computer over a network and plants itself as a separate file on the target computer's disks. One worm was injected into an electronic mail network where it multiplied uncontrollably and clogged the memories of thousands of computers until they could no longer function.

A virus is a set of illicit instructions that passes itself on to other programs or documents with which it comes on contact. It can change or delete files, display words or obscene messages, or produce bizarre screen effects. In its most vindictive form, a virus can slowly sabotage a computer system and remain undetected for months, contaminating data or wiping out an entire hard drive. A virus can be dealt with using a vaccine, or antivirus, which is a computer program that stops the virus form spreading and often eradicates it.
