These are some of the best personal firewalls and Internet security products and services that are available free for personal use.

Important Firewall Installation Tips -- Before installing personal firewall software on a Windows computer, be sure that the firewall built into Windows is turned off. Never use two software firewalls at the same time. Completely uninstall one before installing another. Use the vendor's uninstall utility or if not available, use the Windows add/remove software tool in the control panel.  After you install a firewall, be sure to check it with a service like the Security Space Desktop Audit to make sure that it is configured correctly. Testing your firewall is the only sure way to tell that your computer is really being protected. See our installation page for more information.
