I formerly had PC Tools' Spyware Doctor and Registry Mechanic, but the license has expired on those two and they no longer offer a discount price for getting both programs.

Can you steer me towards something equally good that I should look into getting? I'm looking for protection from spyware, malware, etc.

I'm not locked into getting a Registry cleaner, but would like to.

BTW, I use AVG's updated free version, so I feel I'm covered on the anti-virus front.

Any useful suggestions very much appreciated. Thanks.

I have 3 different Registry Cleaners (Registry Mechanic 6, System Mechanic 4 and Registry Cleaner) and each one of them found different problems with my registry. Which one should I believe?
