What do you use to protect your computer against malware? I've found avast and malwarebytes to be a pretty good free combination. Avast seems to be comparable to some of the paid options in terms of detection, and it's lightweight. I particularly like the silent/gaming mode. As far as anti-spyware, I used spybot, adaware, spyware blaster, and a few others years ago, but they eventually became bloated and almost spyware-like themselves. Malwarebytes is rather good though.
