Santa IM worm hits AOL, MSN and Yahoo | CNET News.com

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, according to a security advisory issued Tuesday by IMlogic.
