What is wrong with the Windows firewall?
I've always found it to be excellent.
You'll find it in the control panel.
Go to: http://www.grc.com/default.htm and follow the route for SHIELDSUP and TEST ALL SERVICE PORTS. Test the Windows firewall there. If it fails, and I doubt it will, then I like the Sygate one for its simplicity.
