Just to put in my 2 cents, i have avast premier also, and i just checked to see if there were any updates. Yayy to my surprise i had an update to go tp version 2014.9.0.2013. After a required reboot i can finally open the game. Before the reboot i added minecraft.exe to the list of application rules setting it to all connections, and i also set java to all connections. I have a feeling the update is what fixed it. Good luck all!!!!
