Need small, free, frequently updated internet/virus/malware protection?

I finally removed a malware virus on my pc. It took 4 differnet programs to finally get rid of it. Im tossing nortons. Which antivirus,spyware, and firewall programs use the smallest amount of memory, are preferably free, and have frequent updates. Dont want to have 4 spyware programs running at the same time.

Same as the other person said. Personally I LOVE AVG Anti-Virus Free Edition. You can download it from www.download.com or from their website www.free.grisoft.com
Norton, AVG , Avast are free antivirus software. Ad-aware, Ewido are free spyware removers. You can download free softwares at http://fixit.in/antivirus.html and http://fixit.in/spywareremover.html
AVG
try something called AVG 3 (free edition)

it updates itself every time you switch on.

a message comes up on the screen when theres a threat and it gives you options of what to do about it.

i found it really useful, probably better than norton.

you can download it here:
