nandemoari writes "A new variant of the Conficker/Downadup worm has been detected. The worm opens a backdoor on an infected machine and allows hackers remote control of infected PCs. Dubbed Conficker B++ (and not to be confused with Conficker B), the new variant of the worm opens a backdoor with auto-update functionality, allowing a hacker to distribute malware to infected machines. It's difficult to know exactly how long Conficker B++ has been circulating, but researchers first noticed it on February 6 of this year." If this seems familiar to you, it probably is.
