What is a firewall?
A firewall is a method of protecting your computer from unauthorized access; this is accomplished by blocking and / or restricting ports which your computer uses to communicate with the internet. Trojans, viruses and other programs look for missing patches and will open a port to listen for commands from hackers. Test My Firewall helps you locate these open ports by identifying your open ports.
