I have Avast IS and Windows 10. I run a scheduled scan early every Sunday morning.
It appears that any time after this scan runs, the PC will not complete a full Restart. PC will begin the restart, then lock up: monitor is blank, power is still active, but no operations can happen. Sometimes the Windows error “honk” will sound. I have to do a hard power down, then start up. After this, things work fine. I can initiate another Restart, which will run fully. I think even Restarts initiated by another app (e.g. “Do you want to restart now?”) are affected by this lockup.
Any idea what’s going on here?
