What is Worms?

Mydoom is a type of Worms.

Worms are virus-like malware with destructive codes, and are able to mutate, replacing their own code by themselves. This makes worms very dangerous, hard to find, and difficult to delete. Like most viruses, worms may spread to the other computers by secretly emailing themselves to Internet users in your address book. The key difference between a worm and a virus is that worms replace your files, rather than simply inserting themselves into your files.
