AvastUI.exe not running

General Topics
1

Hello!
I’ve been running avast for as long as I have a PC, and never encountered a problem like this.
Recently I’ve been away for a month, so I haven’t used my PC at all. When I came back yesterday, I noticed the issue in the title. The UI won’t open. I followed the repair instructions, repaired and rebooted. I got a BSOD, “INACCESSIBLE_BOOT_DEVICE” to be exact. Ran all kinds of commands on cmd, and eventually settled for system restore. Restored the system to the last stable point, which was yesterday’s, and still the same issue. The process opens, stays for a few miliseconds, then disappears.

Also, during my playing around with CMD at advanced startup repair, I noticed that it said my PC doesn’t have enough memory for some process.
Is it malware, file corruption or aught else, and can I fix it?
Thanks in advance!

- Which Avast..? (Free/Pro/IS/Premier) - Which version..? - OS..? (32/64 Bit..? - which SP/Build..?) - Other security related software installed..? - Which AV(s) did you use before Avast..?

It might help to share some system specs.
What OS ??? What was the last thing you did before the problem started ???

Sure can.

Would also like to add, I bought this PC, came with the system.

Was there a trial version of an AV installed when you bought it ??? How was it removed ???

Ah sorry, meant the Windows 10 came as it was.
I installed Avast and the rest of the software currently on it.
And no, no trial.
