A-squared was my backup long term deep scanner. I use Adaware Pro and MBAM as lightweight blockers, but for monthly or midnight scans A-squared was the one for me.

It would even find remnants and trace files, and registry problems after a malware fight.

Only thing is, it recently quit updating after a MS update; so I downloaded Superantispyware as a substitute.

Things have been so clean lately, I don't find anything from any of the utilities I use; BUT MBAM is always popping up telling me it is blocking some IP or malware download some where.

So I suspect it keeps MOST problems at bay, as a daily lightweight solution, for too-late cleanup A2 or SASware is the answer.

Superantispyware is always offering cheap 9 dollar real time protection, but haven't got a chance to try it yet on a client.
