decker This nasty little thing is spreading like wild fire....
If you get a message on MSN that says: "wow, this is you? hXtp://www.messXngerstats.net/proXile.php?youremailaddresshere@yourdomainhere.com" (broke the URL so it doesnt automatically mark up) DO NOT CLICK IT. Instead, log off MSN and go to housecall.trendmicro.com and scan yo damn computer and stop the madness!
EDIT: Seems housecall can't see it yet, so the next thing I'd recomend is SPybot S&D
