Should I use AVG or Windows firewall?

I'm trying AVG trail version and I was wondering when it asks, should I install the avg firewall and disable the windows or keep ther weindows firewall on and disable the avg one. BTW I'm running Windows 7 rc 64 bit.Should I use AVG or Windows firewall?
you should NOT use either, avg has let in viruses before and windows firewall comes from MICRO$OSFT!!! get a proper anti virus like zone alarm, bit defender or sygate, they're all antiviruses which also come with firewallsShould I use AVG or Windows firewall?
use avg. It's very good :)
Windows firewall is very good it even lets you open passive ports, as well as opening ports for programs. Windows firewall is the best free firewall, zonealarm free is crap, most paid firewalls are crap. Stick with Window's they got the firewall right... everything else... not so much.
If your going through a router you already have a physical firewall so you really dont NEED a software one anymore...although if you decide to have one the windows one is perfectly fine for the job.
i like comodo firewall
The best free firewall I've used is Comodo Pro (although the anti-virus you get with it is pretty rubbish).I've never been impressed with Windows Firewall. It seems really quite basic.I haven't used AVG in a while. It used to be good, but as time went on it became more and more resource intensive and generally more intrusive with each update. Eventually I decided to stop using it and switched to a combination of Comodo and Avast! (and have since moved to Kaspersky).Zonealarm is terrible. Avoid it.

The gui for Windows firewall is crappy, but you can configure the hell out of it. Also on WIndows 7/2k8R2 they pimped the hell out of it, it's really advanced now, domain, public, private profiles, configure outbound and inbound policies with a gui, vewy nice :)
I find AVG to be a bit bloated. Xp's Firewall is one way, Vista's is a bit better. I use Online Armor.
