OK yesterday, i saw that avast 5 was out. I used to have avast 4. So when i downloaded avast 5, and rebooted. Then i saw the BSOD flash and then it would keep rebooting, until i clicked safe mode. So I did a system Restore, to the time that avast made a point to when i installed avast 5. Did everything went to normal, but then I noticed that the Windows Security Center said that "Avast! antivirus 4.8.0 [VPS 000000-0] reports that it is turned off" But i can't find avast anymore. So I downloaded BitDefender, and it got rid of the message, but i really didn't like BitDefender so i uninstalled it. The message came back. So i tried downloading Avast 4.8 again, but the message won't go away. And i think it gave me Avast 5. And now avast says " Your system is not protected. Please use the FixNow button to start protecting your system" So i clicked FixNow button, but it doesn't do anything, I also clicked Start Program, but nothing still happens. Plz Help.
I'm using Avast Pro edition
(P.S) Nothing Works on Avast!
