I have given up on windows 8. I reinstalled it 4 times every time I installed avast it would go until I would go to desktop then freeze.Restarting the PC would do nothing it would come back on, frozen on desktop. I wasn't overly fond of the way win 8 Os ran.I guess I will never know why and am guessing avast had something to do with it.Anyway I installed win 7,and this asus has never worked better, with Avast doing it's thing
