Cough.
Avg is terrible, Avast is average, but if you want a free AV, I would use Avira or Microsoft Security Essentials.
If you wanna pay go for Kaspersky, which is excellent, or Norton (Which is now very light on resources and includes a behaviour blocker for good Av protection.)
Like sunami says, Never, Never run 2 AVs They'll cross over and create false positives.
You also need a good firewall, I reccomend:
Pro firewall choices:
Comodo with Defence plus
Outpost Firewall free 2009
Online Armor free or paid.
Basic:
Windows firewall. Bad on XP but is fine in Vista and W7, just needs to be configured.
PC Tools firewall
Never use Zonealarm. It is downright bad.
