Well as the title says I got this surprising error quite out of the blue for no apparent visible reason at all. I tried running avast! just to check up on it and after the memory scan, I got this error message which is shown on the attached screenshot. This has never happened to me before until now, and I am running 4.8.1185. Nothing appears to be showing up in the error logs and apparently I wasn't doing anything except simply running avast. After clicking "OK" on that error message though I tried rerunning avast! and interestingly enough this time it ran like it should have.
I'm not sure if I can reproduce this, but I have not rebooted my computer yet If there's anything I can do to do some additional checks at the moment, I'll see what I can do.
