Well it is strange that even avast doesn’t detect this in the VT results.

Are you using Vista, as it seems to be a legit file name for that location ?

Is this the Full System Scan (not a custom or anti-rootkit scan) other than bumping up the sensitivity have you made any other changes ?

Like, test whole files, scan for PUPS, etc.

There have been other instances of this being reported as a rootkit, so what is the malware name given on this alert ?
