I'm not so sure this is a FP. After receiving the alert about Spyware Doctor, and after updating Avast, uninstalling and reinstalling Spyware Doctor, my XP based computer started having numerous problems. The worst of it was the Standby/Shutdown processes began working erratically.
After some extensive detective work I found that the problem was originating with Spyware Doctor, a program that I have used without any problems alongside Avast for ~2 years. I uninstalled SD and things have returned to normal.
