Okay you knew this was coming because of my other thread. So Here Goes. Which has the best RealTime Guard? A Squared Anti-Malware with it's Behavioral Detection besides it's signatures. AVG AntiSpyware which I think uses Heuristics in realtime as well as for on demand, but I'm not sure. Spyware Terminator with it's various Guards and HIPS. SpySweeper, or CounterSpy. And what the heck. Windows Defender with it's realtime features designed for detection in changes made to your PC? Also which one would be best for Firefox protection?
