I have always used AVAST Internet Security on my computer, and it worked prefectly, untill...I've installed Windows 8 on my machine. So I decided to install AVAST IS. As I have noticed, that only a few AV programs supports WIN8, I've checked if AVAST does support it. And on AVAST IS web page it says that idt does support WIN8. So I've downloaded latest AVAST IS and installed it in trial version. Installation went well until system reboot. After WIN boot screen, lock screen and login screen, windows went blank. I mean, I colud login with my microsoft account, but after that, Windows just went blank (I mean black), just black screen. I tried everything, but nothing helped. So I decided to uninstall AVAST IS via TASK MANEGER. After uninstalling AVAST, I rebooted machine and again loged in, the problem dissapeared. Windows started normally. So there was nothing else to do for me but to install other AV program. But I wish I had AVAST on my machine. Does anyone had a same problem in WIN 8, when using AVAST IS?
I must say, after reinstalling WIN 8 and installing AVAST IS, the problem was the same.
