Replacement for ZoneAlarm on 64 bit systems? [closed]

"Comodo works on either 32 or 64 bit versions of XP/Vista and you can tweak the firewall to allow certain ports, programs and also what type of packets are sent through.

It does not allow for blocking certain sites though so you may have to look for something else if that's a deal breaker.

If you do choose to go with it, beware that it's marked as ad-ware by Softpedia for the install to want to add on optional toolbars and such."

On Vista and Windows 7 you can configure the built-in firewall to do outbound filtering as well.
