Protection Firewalls

For protection, and not only from Firewall, this service monitors all the network taps of your connection and does not allow "left" connections without your knowledge. It is useful not only to protect against Nuke, but also protect against Trojans. Firewall is in the program AtGuard , which is now called Norton Internet Security, Besides Firewall there is a lot of interesting things, but it's better not to use this program because It was widely distributed and it was written with many exploits

ConSeal PC FIREWALL many consider this program the best Firewall of all time :) difficult to configure, but then there will not be any problems, you can read more about the setup here .
