After reinstalling windows 8, and avast internet security v8. I went to install world of war craft cataclysm. The launcher was unable to connect to server. I had already installed star craft 2, but it now blocks the sc2 installer from allowing me to play the game. the screen pops up but unable to click the play button. I un-installed avast and rebooted pc. i was able to install world of warcraft and play sc2. So I know that avast was causing the problem. How do I fix this?
Thanks!
