We strongly suggest Uninstalling Avast. Windows has a built in Anti-Virus Windows Security (Defender) It is a lot less obtrusive then Avast and works just as well as Avast or any other Free AV app and it comes with Windows.
As stated in Post #6, go to Search and type CMD, right click the CMD results and Run As Administrator. In the Elevated Command Prompt copy and paste or type the following bold command and press Enter.
dism /online /cleanup-image /restorehealth
When that completes type the following Bold command and press Enter
.SFC /scannow
These commands will replace any missing system files.
