Santa IM Worm Hits AOL, MSN and Yahoo

elmtree95 writes "CNET News reports A Santa Claus worm is attempting to trick America Online, Microsoft MSN and Yahoo instant-messaging users into clicking on a file that delivers unwanted software to a victim's computer. The IM.GiftCom.All worm attempts to dupe IM users into thinking an acquaintance has sent them a link to a harmless Santa Claus file. IM security vendor ELMTree Software has released a patch to their ChatPatrol (www.chatpatrol.com) product to address this issue."
