Suggestions to fight attacks on your computer

I talked with a friend today who asked what I use to fight viruses, malware, spyware, trojans, and attacks in general. I explained that I am currently using AVG freeware version, and some other freeware, or limited version protection software. Along with AVG I use Spybot, and CCleaner, and Malwarebytes Anti-Malware. Stephen and I discussed his use of Avast, which I have decide to try this weekend. At a later posting this weekend I will also list some free movies sites I have reviewed. Ain't nothing better than free. And yes, I am from the South.
