Is it possible that my Spybot log is listing a false positive in this registry key? I am forcing active desktop. There are no other signs of any malware other than this one entry. I've tried removing my forced entry to see if I get the spysheriff desktop message and I don't. As soon as I apply the active desktop policy and run Spybot, it's back. I've also tried changing the value myself with the same result.

My thought is that forcing the desktop is a symptom of spysheriff so it is reported that way but if I have no other signs, it's a false positive.

Thank you.
