Updated Via GUI yesterday, well after first reboot, I goto open Specy to check PC temps a moment while Firestorm viewer (Secondlife 3rd party viewer was open) and suddenly machine totally locked up, (not for sure if related to Avast or not) Also Microsoft Edge stopped working, Cortana and Start menu later in the day. I think in morning gonna try a clean install of 12.3.2279, and retest everything, and see if I can recreate the issues, bugging me, so far today nothing is acting up, so stumped if was related to Avast or something else
Did run sfc /scanow, no intergrity violations found
did run dism online cleanup image/restore health
and chkdsk over night last night--no bad sectors
Temps are excellent for this time of year
So i'll see how Clean install of Avast handles in morning and report back/use support tool then
