This threat has been renamed to Rogue:Win32/Fakeinit.
 
Rogue:Win32/Fakeinit is a trojan that displays fake warnings of “malicious programs and viruses”. It may download a fake scanner that informs the user that they need to pay money to register the software and remove these non-existent threats. Rogue:Win32/Fakeinit also terminates certain processes, lowers security settings, changes the desktop background, and attempts to download other malware such as Rogue:Win32/Fakeinit and Trojan:Win32/Alureon.CT.
