As I said earlier a good software firewall is a must for total protection from computer viruses, because it can prevent intrusion even before they try to enter your computer. If you do not have a good firewall installed on your PC, then it is as good as having no firewall at all. But, how can you test your Firewall’s efficiency?

Comodo HIPS and Firewall leak test suite can be use for this, which simulates a range of dangerous exploits including Root Kits, Background Intelligent Transfer attacks and process, injection attacks, etc.

Download and unzip it. Run the program by double clicking on clt.exe file. Now click on ‘Test’ button for analyzing. If your firewall passes the test, it should warn you that CLT.exe is trying to modify important system files. More information….
