Comodo Firewall hangs Unity in fullscreen standalone mode

Hi, all! We have a bad issue with Comodo Firewall and the deployed version of our game (Win7 / 64). When out game starts, it sets the last saved full screen video resolution (or the default if it's the first time you launch it). The problem is that at the same time, Comodo Firwall try to prompt user with a popup (to know if it have to block internet access of the game or not). In the meantime game is started in fullscreen mode and everything hangs. Tested on two different computers, need to hard reset PC.

Thank you in advance.
