Ok here is my current setup: Win7 64bit Nod32 v4 Mamutu Z antikeylogger Threatfire I also have a lifetime lic for Outpost but I am willing to try another firewall while outpost works out it's wow bug (currently outpost is not installed). So I am thinking of trying out OA 5, however how heavy on resources is OA? Do you notice system slowdown? A popup deluge? Mind you I am also a gamer so I would hate to see popups while playing a game.
