Boot scan problem
« on: January 28, 2023, 11:00:54 AM »
My Avast premium free trial recently ended but I kept the free version and I vaguely remember I changed some settings so maybe I scheduled a boot scan by accident.
Now this happened:

1) Today I started my pc and there was a blue error screen saying that I needed to restart, nothing happened so I turned it off using the start button.

2) I turned it on again and there was a "no bootable device" message so I turned it off.

3) I turned it on for the third time, there was a terminal window for a second and now I'm stuck with a "Avast Antivirus is loading..." and a loading bar on black screen.
If I press esc nothing happened, I can't even turn it off because if I press the start button nothing happens again.
It's been like that for almost one hour and I discovered the very existence of a boot scan like 15 minutes ago.
Is it normal that it takes so much time? Should I just wait hoping for the best? What can I do?

not sure.

the continuous loading screen is a known issue for months and talked about here with a fix to revert back to the old boot scan

but, as youve now reverted back to the free version it could of messed something up so causing a blue screen.
if you can get back to your normal log in screen then open avast UI and see if you can find the geek area by following this as it says it applies to premium and avast free.

i had similar when it first happened but cant remember a bsod. hard turn off 2 times and turning on just continued with the loading loop.
try turning off, unplugging from mains for 15 minutes, then trying again. worth a go while you wait for others to advise.

Ok, this is quite interesting but I had same issue and the fix was quite surprising. I decided to lower refresh rate of my monitor to standard 60hz, and then boot scan worked. I made account just to write this post, so I hope it will be useful to anyone.
