For perfect free anti-virus,use active virus shield(download from http://www.activevirusshield.com/antivir... you want to buy anti-virus,buy Kaspersky,it is the best.For free anti-spyware,use spybot search %26 destroy.But the best anti-spyware program is SpySweeper(you have to buy it).
Yeah but you have to pay for it. Its called Norton 360. I'm using that and its really helpful
I used to use Symantec producs for a long time , but I`ll never do that mistake again. They broke my PC and I didn`t even had a virus or spy. Anyways as also stated before, they`re all kinda`the same, it`s also about the user using the PC. It depend how often do you do scans and updates.

AVG it`s a very good one , I`m actually surprised you got a virus using AVG. You also need to realise that it`s ALWAYS the virus that comes out first and then the antivirus companies release an update to fight/delete/cure that virus.
