Santa Claus Worm delivers bad present to IM users
Anti-virus companies are warning instant messenger users to be wary of joke messages and e-cards as they may contain the Santa Claus worm.
IMLogic, a company that specialises in virus detection in Instant Messenger programs warned last night that the IM.GiftCom.All worm presented itself as a harmless Santa Claus file, apparently sent from someone known to the recipient.
Victims who clicked on a file link would see an image of Santa Claus but in the background the worm would be loaded on to their computer, IMLogic said. The worm would then send the same message to people on that person's address list possibly spreading like wildfire across the internet.
