to Everyone who has just answered the question: these solutions suck. Manual removal is so much easier, go post somewhere else.
solution:
OK dude, heres how you back door this mofo.
1: --safe mode -- gtf in there. (restart, F8 after motherbord screen, or you could tap f8 frantically and im sure it will work as it always has...)
2: --unhide hidden folders-- its in your tools (control pannel, folder options, man up and look around)
3: --App-Data-- find that folder (users, *username* , for me c:\users\*username*\AppData\roaming)
4: --have fun-- If you dont have a \roaming folder in your app data folder start looking around for the most recently changed folders. your target is "privacy.exe", what i reccomnend you do is switch view to "list" or "details" and sort by date modified and start looking for "application" in the types colum. if you dont find it... MAN UP AND DIG AROUND.
THIS IS THE MOST DEFINITIVE SOLUTION FOR THIS TYPE OF MALWARE
YOU DO NOT NEED ANOTHER APPLICATION TO REMOVE IT
DO NOT TRUST JERKS WHO TELL YOU TO GET ANTIVIRUS CRAP
if your still experiencing problems, shoot me an email
---edit---
@orabus, @Micheal, @John, @Ashok, those are good enough ways, but the those programs are cumbersome and cannot always catch TrustedInstaller, the jerk who has all the permissions and keeps installing malwar as an admin. (hes actually created when the user gives permission by accidentally clicking something) Manual removal is both experience building, and more constructive towards the Yahoo answers goal, to provide comprehensive feedback and not just links and advertisement.
