Hi MrDerfla, I am Rob, a volunteer and a 10 time and dual award MVP specializing in Windows troubleshooting and Bluescreen analysis.

I would uninstall Avast and then run its maker's removal tool. Use Windows Defender which in Windows 8/8.1 & 10 is a full antivirus.

Contact Avast Support and their forums.

Then do these:

Windows Key + X - Command Prompt (Admin) OR Windows PowerShell (Admin)

(Run these one line at a time.)

SFC /scannow

Note if that shows uncorrected errors - continue regardless.

When that completes run these :

DISM /Online /Cleanup-Image /CheckHealth

DISM /online /cleanup-image /scanhealth

DISM /online /cleanup-image /restorehealth

Note if that shows any uncorrected errors - continue regardless.

Then restart the computer.
