I am using ESET Internet Security. I have it set to interactive mode so it asks me every time something tries to connect to the internet or if there is an incoming connection so that way I can manually enable or disable whatever I want. I know ESET is not causing any issues. I gotta look into my router settings then.
It just pises me off when I see a lot of people have 0 issues and I can not even connect to a game to play 1 full match from start to finish.
