Need firewall-only software compatible with Vista-64

Now that Comodo has discontinued their support for their free, firewall-only software in favor of their new anti-virus/firewall all-in-one package, I'm left looking for a new firewall that is reliable and compatible with Windows Vista 64-bit. I already use Avast Antivirus (not really willing to part with it), so I'm looking for just a firewall that doesn't come in a bundle package.

I've looked here http://forums.majorgeeks.com/showthread.php?t=44525
Of the list of recommended firewalls provided here, the ones that don't come in bundles aren't supported by Vista 64 operating system.

Any recommendations for me? Much appreciated, thanks!

P.S. Would anyone care to comment how reliable Windows Vista's built-in firewall is? (I'd rather not rely on this unless there are no better options available for me).

 

From what I've read in the link below, one can select the Firewall only. http://forums.comodo.com/overview_cis/comodo_internet_security_overview-t31059.0.html

Just make sure you download the 64 bit version.

Here's a list from Microsoft in what's available in soft and hardware for the 64 bit version.

As long as you have a router between your computer and the 'net, Windows Firewall is fine. As far as WiFi is concerned, don't use it until you can get a good substitute in 64bit form.
