If you have windows XP with SP2 installed on your computer, you already have a basic firewall running on your system. Windows Firewall monitors incoming traffic to your computer, but lacks the ability to monitor outgoing traffics, that means that any malware that gets installed on your computer has the freedom to send out information without windows firewall detection. Comodo firewall is a full firewall protection suite; it protects incoming and outgoing traffic on your computer. Whenever a program gets launched in the background, you get a pop-up alert like the screenshot below.

Comodo version 3.0 features a fully fledged Host Intrusion Prevention System to protect your critical operating system files and block viruses and malware before even they get installed.
It features a friendly graphical user interface; highly granular configuration options; easily understood and informative alerts; wizard-based detection of trusted zones and much more. Comodo Firewall Pro delivers enterprise class protection and can be used ‘out of the box’ – so even the most inexperienced users will not have to deal with complex configuration issues after installation.

These are the benefit you get when using Comodo Firewall:
- Constantly monitors and defends your PC from internet attacks
- Gain complete control over which programs are allowed internet access
- Patent-pending Clean PC mode maintains any new computer as a virus free computer
- A-VSMART prevention technology is a next generation Anti Virus, Spyware, Malware, Rootkits and Trojans (VSMART) platform that prevents harmful applications from getting installed on your system
- Host Intrusion Prevention System can stop malware ever being installed
- Stay protected against new threats via automatic online updates
- Real time traffic monitoring enables you to react instantly to threats and identify bandwidth bottlenecks.
- Easy to use interface and quick setup
- No license fee – complete protection at no cost for networks and home users
In case you’re wondering what’s the catch on this firewall being completely free. Well, they give out this free software for the purpose of branding their Comodo name. If you are in the market with a product, then you probably know that branding is really important, so these guys do the branding by giving out a free firewall, and make the dough selling SSL certificates. Is a win/win game

Okey, this is definitively what I was looking for. Found some other softwares but I was not feeling really safe in installing such things, but if my bud Nelson writes about it, than damn yeah it is safe.
Thank you Nelson
