League of Legends (TM) Client has stopped working, game won't start after champ select.

Like the title Implies everything works fine till the moment the game begins after champ select. Game won't start and crashes every time I reconnect. I can't play games nor can I start any kind of game. My Pc is highend enough it shouldn't have any problems tech wise. Have been having this problems maybe since the patch started. Just wanted to see if I was the only one having to deal with this problem?

If it could get fixed I'd be greatful enough, I need get gold before season ends man. please man. please. Patches have been making the game worse each time

Had a problem before during last patch but it quickly got sorted. E.g. FPS drops after 10 mins

Cheers cheers -Broke

EDIT: AVG was stopped me from loading the game after Champ select. Thank you friends and Riot staff for point it out. Sorry for wasting your time. :)
