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.
