FWIW, I was able to (relatively) easily remove Poweliks from a test Win 7 Pro x64 Virtual Machine using a combination of Farbar's Recovery Scan tool, RogueKiller, Eset Services Repair tool & a few others like MBAM. Sorry I didn't reply sooner but I haven't had much time to "play" with malware samples lately until last weekend.

If the above tools still don't remove every trace, then it's time to drop "The Hammer" -- ComboFix
