A firewall controls the door to your computer and allows only traffic you understand and initiate.

Comodo Firewall constantly monitors and defends your PC from Internet attacks. It’s easy to install and use and passes the industry’s most stringent firewall “leak” tests. However, there have been reported from time to time deficiencies, such as 100% CPU use by Comodo’s agent (cmdagent).

Another great solution is the PC Tools Firewall Plus. By monitoring applications that connect to the network Firewall Plus can stop Trojans, backdoors, keyloggers and other malware from damaging your computer and stealing your private information. Powerful prevention against attacks and known exploits is activated by default while experienced users can optionally create their own advanced packet filtering rules, including IPv6 support, to customize the network defenses. Features: Regular Smart Updates, real-time protection, comprehensive network shielding, No interruptions when playing full-screen games.

ZoneAlarm Firewall protects your DSL or cable-connected PC from hackers. This program includes four interlocking security services: a firewall, an application control, an Internet lock, and Zones. The Internet lock blocks Internet traffic while your computer is unattended or while you’re not using the Internet, and it can be activated automatically with your computer’s screensaver or after a set period of inactivity. Zones monitor all activity on your computer and alert you when a new application attempts to access the Internet.

Remember: Comodo firewall may consume a lot of resources, depending on the configuration of your system. If you don’t want to risk, just install ZoneAlarm, or, even better, the PC Tools Firewall Plus.
