I need to know what a good firewall program to use.

Your "firewalling" should be in layers. First, use an ISP or email client service that offers online (server side) virus, spam and content filters. Second, use a hardware router with a built in firewall between your modem and your computer or network. Third, install personal firewall, anti-(spyware, virus, trojan, spam etc) software on your computer. Lastly ensure you have the latest definition updates for the softwares listed above as well as windows, avoid the use of two software firewalls or anti-virus programs at the same time. Completely uninstall one before installing another, and remember to audit your system for an accurate security evaluation once you get everything in place.

Sabertooth's solution is the best, but if you just want a software firewall, get Sygate.

Hmmm, a good 'belt and braces' solution from sabertooth! I would definately recommend a hardware firewall (be it a dedicated firewall box or router with built in firewall) if possible. It all depends on your budget, are you looking for a free solution or do you have money to spend? Are you looking to protect a network or single PC? Do you really have 5GB RAM ??? Wizard ICT.
