I can't get to the desktop using Windows button and D. And I can't get task manager to pop up. A window appears but before it becomes the task manager, it disappears after about 1/2 second. I can't get past the black screen / mouse cursor. Occasionally I get a flashing blue screen where the whole screen flashes blue/off/blue/off etc. Luckily I don't suffer epilepsy....
Everything was fine before I installed Avast. Now I can't get to the desktop. What a mess.
Can I boot up from some form of bootable drive and fix it that way? It seems unlikely I can fix it from within Windows as I can't get into Windows to start with....
HELP.
FOR PEOPLE WHO CAN'T ACCESS TASK MANAGER or SAFE MODE, I HAVE FOUND ANOTHER METHOD..
After login, Press Ctrl+Alt+Del then, click on the Power button. It'll show some error, click OK.
Then, there will be an Error Report. Click on More Details, Scroll down & click on the last Hyperlink (Blue, underlined test). This will open text report in Wordpad.
Click File -> Open. Select All Documents from the dropdown menu at the right-bottom of the window.
Browse to "C:\Program Files\AVAST Software\Avast" & look for AvastUI, Right-click on it & Run as Administrator..
Now you can add the explorer.exe & SystemSettings.exe to Behavioral Shield exceptions as mentioned everywhere.. Restart...
Enjoy!!
