Yes looks that way, as I mentioned, GData also uses avast as one of its two scanners.
In the meantime Restoration should be OK, but you will first have to exclude the file and full path (C:\Program Files\Spyware Doctor\avdb\temp\*.vbt) from the standard shield or when you move/restore it avast will alert again.
However, having had another look at this file name and path (shouldn't have been so quick first time round) it looks like isn't a false positive in the true sense as I suspect this may be bad practice on the part of Spyware Doctor by not encrypting its virus data base. That is why I have but the *.vbt in the path as if this is truly a temporary file the numbers are likely to change and the * is a wildcard that should take care of that.
So avast has been able to take a peek inside the avdb (AntiVirusDataBase) temp folder and .vbt file and found a pattern match to a virus signature.
Were you doing a Spyware Doctor scan or a Spyware Doctor update at the time of the alert ?

I don't know if in the light of what I have said above if this should be sent to avast for analysis, but it won't hurt:
You can send it from the Infected Files section of the Chest (select the file, right click, email to Alwil Software), as a Possible false positive, you could give a link to this topic to help. It will be uploaded (not actually emailed) to avast when the next avast auto (or manual) update is done.
