Defense+ Question

Hi there

Well I have recently installed a game on my PC, which uses an anti-cheat software called GameGuard, but Comodo detects this as a root kit (but it’s not, it’s not harmful, but it thinks that it is trying to carry out root kit like activites I think). The only way I can play the game is if I disable Defense+. Is this recommended? Will this completely disable my firewall or just the protection from root kits and things like that?

Thanks for your help and time.
