I also ran scans with a-squared which came back with nothing , SUPERAntiSpyware also came back with nothing, Avast scan came back with nothing. DR.Wed Cureit came back with nothing

This can go either way but more often it looks like it would be a FP and will be removed in the next update .

There is no way that we can tell from the outside if the user has set this key or if malware has .

[TeMerc]

I had a user earlier who said this setting was due to him replacing task manager w\Process Explorer.

This should be resolved .

This issue appears to be fixed, but after scanning with 1820, wextract. exe is flagged as "Trojan.Vundo".
