Been using AVAST FREE on Windows 8 RP x64 for a couple of weeks now. Upgraded to v7.0.1451 today and after reboot everything is fine until I log in, then I just get a blank black screen. Booting to safe mode and uninstalling AVAST cures the problem. Tried it several times, so definitely caused by the new AVAST update.

Thank you for the update.  I am aware that there will be a fix of some glitches  this coming week, but I haven't heard of this one.  The Avast Team does read the forum, so thank you for posting.  :)

I had similar problems. Windows 7 boot hanged on welcome screen. Finally i pin-pointed the problem to avast. First i disabled avast start-up in safe mode.  After that Windows booted normally. Then i decided to look at avast "troubleshooting" settings, and disabled rootkit scan at start up and also quest user settings. After doing those Windows booted up normally with avast enabled. I think it was most likely the rootkit scan option that somehow prevented Windows from booting normally.

Edit. Want to add, that couple of times it went through the welcome screen and then the screen went black (like in 'xma1e' case) and booting hanged. The problem is now solved by editing some avast settings, like mentioned earlier.

Thanks for the info. Does "Service program update 7.0.1456 " fix this? Not tested it yet.

Have either of you tried an Avast Repair to see if this fixes your problem:

XP Users:
- Go to Control Panel > Add/Remove programs > Avast Antivirus.
- Scroll down and choose Repair function in the pop-up window.
- Reboot.

Vista & Win7 Users:
-   Control Panel
-   Programs & Features
-   Uninstall a Program > Select Avast Antivirus
-   Click the Change/Remove button and scroll down to Repair
-   Click Next and follow.
-   Reboot.
