''Wyrm'' is a 1998 novel by Mark Fabi.

Michael Arcangelo is a programmer who specializes in combatting viruses and worms. When hired by a team that programmed a revolutionary chess-playing AI to investigate problems with their computer, he discovers evidence of a sentient computer worm. This program, Wyrm, has already stealthily disseminated itself across the Internet. It falls to Mike and a motley collection of fellow hackers to stop Wyrm before it brings about armageddon.
