I realize you're after an answer for a software based firewall, but what we're trying to tell you in a not so helpful way is that it isn't recommended to put a software firewall on an OS. It adds overheard, can cause instability, and if you're that worried about malware sending things from your box then you have a bigger issue than a firewall will help.
The recommended method is a hardware based firewall, put the server in a DMZ behind the firewall and it's not allowed to be touched with anything besides the approved upon open ports, and put antivirus on the computer. Keep up with updates and patches and your server will be just fine. Also if you can try to move different services to different servers so if there is a 0 day vulnerability it will only affect one server.
