Computer Worms are programs that spread themselves from computer to computer over a network. Worms, unlike viruses, do not infect programs, diskettes, or files with macro capabilities. Instead, they make copies of themselves and send these copies over the network to other targeted machines. Like viruses, Worms come from anonymous or untraceable sources. Worms are often equipped with dictionary-based password crackers and other cracker tools that enable them to penetrate more systems.
Worms often steal or vandalize computer data.
