Turn firewall and antivirus intrusivity to their lowest settings, the most common issue are alert messages that in Avast, for example can be set to be disabled when full screen apps are running with a "game mode" setting (it doesn't turn the antivirus off, protection is still running), for Zone Alarm there is a game mode too (but let's say it, Zone Alarm is quite crappy anyway), Comodo never gave me problems, so I guess this mode is set by default and I guess most antiviruses and firewalls offer this feature.
