Hi, just wanted to know if there's any good 64-bit firewall software out there, 'cause I'm finding difficulty finding anything other than 32 bit, and none of them have worked yet. Thanks for anyone that knows something.

Running Win XP Pro 64bit

Comodo has a 64bit version
Youll see it on their free firewall download page.

Here's the link
Comodo Firewall ProVersion 3.0

Thanks a lot, it's working great.

You're welcome
