While SuperAntiSpyware has an unfortunate name, it is a scan tool worthy of addition to your arsenal of spyware/malware protectors. I've used this application for only a few days but recommend it heartily. It’s speedy, too. The most recent scan of my storage was completed in 10 minutes. This useful program does a thorough job of scanning your system for dangers, and then deletes any it finds. SuperAntiSpyware scans not just your files and memory, but your Registry as well in search of potential dangers.
There is a pro version you can pay for, but I'm using the free one and think it is all I need.
