Unless I'm misunderstanding you, you stated when you removed the file MBAM detected as infected, some of your programs were blocked from start up. You suspected it might have been a false positive. Why would you want to try to (again) remove the file, without confirming whether (or not) it was a false positive?
It would help if you update MBAM, and then run another scan. Please post a copy of the log.
MBAM has reported one of my c:\Windows\Temp\TMP files as infected (with Trojan.Dropper). I tried removing it with MBAM and after that some of my programs are blocked at start up. Restoring that file followed by a System restore put my PC back to normal.
Neigher my AVG nor SuperAntiSpyware scans reported any malware, I suspect that it is a FP, therefore I am thinking of doing a disk cleanup to try to get rid of that file instead. My question is, if that file is indeed infected, would it be sufficient to get rid of it using disk cleanup?
