My wife's computer is infected with a malware known as "Personal Antivirus". She inadvertently loaded the program. We've tried a full system scan using Avast and its option to scan prior to the Windows OS starting. It didn't remove the program. We've tried Spyware Terminator and I don't think that's finding it either.

I've gone to PCWorld.com from my unaffected laptop for some info and I see there is a paid advertisement for a free "Spyware Doctor" that is allegedly supposed to remove the malware completely.

Am I going to need to reinstall the OS on this PC? The last thing I want to do is purchase some other antivirus software that claims to be able to find this and remove it and then find out this malware flies under that radar as well.

Any advice? My wife is wondering if she got this by spending time on Facebook.
