voila ce que dit symantec a propos de ce worm :
W32.Spybot.Worm is a detection for a family of worms that spreads using KaZaA file-sharing and mIRC. This worm can also spread to computers that are infected with common backdoor Trojan horses.
W32.Spybot.Worm can perform different backdoor-type functions by connecting to a configurable IRC server and joining a specific channel to listen for instructions.
