Not sure if any of you have run across this one but someone brought a laptop by today that was infected with this.  Nasty, Nasty virus.  From what I have read the only thing that will clear it is Blacklight by F-secure (link is near the bottom of the page).  This thing sits on the system and throws up fake security center warnings and will do browser hijacks when you go to financial websites.  Be careful with this one.
