Help! There Are Worms In My Computer!
By James
We've all heard of nasty worms that can infest our dogs and cats. They can seriously harm our pets if left untreated. Well, the same can be said for the worms that can crawl through your computer, too.
Computer worms are programs that reproduce themselves by using networks to send clones of themselves to other computers that are attached to the network-and they do so without any help from you. Although this description of a worm might sound much like a virus, there are some major differences.
Unlike a virus, a worm does not need to be attached to another program; it is a standalone program. Worms, even if they're intended to be harmless, will always do damage to the network, though it might only be using up extra bandwidth. A virus attacks and corrupts files on a computer.
The very first worm was actually created with the intention of performing a useful task. Researchers at Xerox PARC by the names of John F. Shoch and Jon A. Hupp designed a worm to move through a network and identify processors that were not in use. The worm would then assign tasks to these processors so that the network would run more efficiently. They dubbed this program a "worm" using inspiration from the science fiction novel "The Shockwave Rider" written by John Brunner.
Sadly, after Shoch and Hupp's useful worm, hackers began to exploit the idea for their own purposes. Among the first worms to appear on the Internet was one created by Robert Tappan Morris, who was a student at Cornell University at the time. Called the Morris worm, it sped through the Internet and infected numerous computers before Morris was identified and convicted of violating the Crime and Abuse Act.
Computer worms exist in several varieties. There are email worms that are spread through email messages. They arrive in your inbox attached to email messages or an attachment might direct you to a site where the worm code lies in wait. Once it's activated, the worm gathers email addresses from your address book and spreads to your family, friends, and contacts.
Instant messaging worms spread by using your IM contact list to send links to websites with worms or the worm
