i use:
Avast! Pro
Firefox 2.0
Spybot
Adware
and i run a program called "DU Meter" its a download/upload status bar, always letting me know how much im dl/uling it, i originally got it for fun, to keep track of how much i DL, but ive learned its a GREAT tool for diagnosing computers, if **** is on a computer the upload will spike up on its own without any programs running
Avast! Pro, i stand by it 100%, love it
but ive used NOD32 and i have no complaints with it, those are my top 2 choices
with avg: i bet 80% of hte people using avg, if they were to switch to avast pro/nod32, they would find out they arent as clean as they think
remember: Just because you dont NOTICE the virus, doesnt mean its not there.
