 Computer Worm (Definition)
Worms are very similar to viruses in that they are computer programs that replicate themselves and that often, but not always, contain some functionality that will interfere with the normal use of a computer or a program.
Worms take advantage of automatic file sending and receiving features found on many computers.
A worm can spread itself automatically over the network from one computer to the next.

 Year of the Worm CNET News.com
Unlike worms and viruses, the purpose of a Trojan horse is not to spread, but to have a particular target--that is, a computer's owner--to run the program.
Because worms can't rely on file-to-file transfers to spread their code, they need to have a way of sending themselves to other computer systems.
The worms created with such generators can vary from benign mass mailers that clog e-mail gateways to vicious code that is the equivalent of the Ebola virus to computers.

 Technology News: Security : Swen Worm Infects Over 1.5 Million Computers
The Swen computer worm is turning out to be a bigger problem than earlier expected, using a brief head start on computer antivirus defenses, as well as complex abilities and an effective masquerade, to infect Windows machines and spread via e-mail to many users.
Classified as a worm because of its ability to copy itself without infecting host files, Swen represents a high level of sophistication in its ability to execute code automatically, its deceptive spoof of Microsoft correspondence and its randomization of information that could be used to identify it, according to Sunner.
Sunner likened the worm to the original Gibe worm, but said it was written in C++ and also used an SMTP engine, adding to the indications of a highly sophisticated author.
