Unfortunately this product is not up to the standards of Comodo's peerless firewall, which of course can be forgiven considering that it's still in its Beta phase.

I adore the GUI and other aspects of the interface; however it simply did not deduct a selection of malware I downloaded to test my security software. The HIPS (which is made redundant by Comodo firewall) cannot be turned off during install, which means it can cause problems after the reboot before it can be deactivated.

No doubt version 3 (first Alpha) will be an outstanding product which blows its rivals out of the water, but until then I'll be sticking with Avast!

An outstanding firewall and Host Intrusion Protection System (Defense ), which performs at 100% in leak and intrusion tests. I was previously using PC Tools Firewall Plus which performed dreadfully in these tests, so I uninstalled it and downloaded Comodo.

Using the Defense service effectively requires some patience and study, but this effort is worthwhile if you are concerned about online security. Even if this product was not freeware, I may have been tempted to 'bite the bullet' and shell out, it's that good.
