Best Free Firewall

What is the Best Free Firewall available to Download?

Simply put a Firewall is security program that filters the data coming through a network (or Internet) point into your private computer. If incoming data falls short of the security measures specified in your firewall then the data is blocked and an alert raised. A Firewall is crucial for protecting against malicious viruses, spyware, spam and unauthorized access.

I have put together a complete list of the “Best Free Firewall Software” that describes the best free firewall software that is available to download for free and without registration – please choose the firewall that best your needs and use it effectively to protect against threats to your computer’s health.

  • Comodo Firewall **** – brings excitement back to the free-firewall category with a spiffy interface and impressive performance. It protects any Windows 2000 or XP SP2 system from hack attacks, and it blocks unauthorized programs from using the Internet—even programs whose malware-style trickery fooled some other free firewalls.

  • PC Tools Firewall Plus *** – a good firewall for protecting Windows users against threats on the Internet, and is far better than the built-in firewall due to its easier-to-use GUI As well as level of customization. Also, its prompts are far less annoying, so that it is much suitable for home users. However, unavailability of component monitor, detailed access level permissions, and full internationalization support may put that piece of software second to ZoneAlarm Free, and third to Comodo Firewall.

  • Outpost Firewall FREE ** – The FREE version of Outpost Firewall offers a basic protection solution for casual web surfers and low budget systems. On the plus side the Open architecture allows third-party plug-ins and presets help handle permissions for known program types. On the negative side Outpost is not recognized by XPSP2 Security Center and is easily disabled by malicious software. Overall best avoided for average users but offers plenty to computer savvy folk – geeks :) Download Outpost Firewall Now
