It didn't help, at all.
The scan has completed, found around 200 objects and I was prompted to restart the computer to clean it all but... same old same old. Freezes or shuts down.
The malwarebytes shield blocks "incoming/outcoming" threats.. so I guess all is not cleaned, right?
I forgot to mention that when this freeze or shut down/BSOD/restart happens - I can't immediately restart the PC
- it freezes again on the windows screen:
So I have to reset it repeatedly for like 5-10 times to get it going again. Or if I get to shut the computer down and then wait several minutes I can restart it.
Such a sad story.
