I apologize, but I don’t really understand you. My original comment about Windows Defender being “off” in Action Center was originated in YOUR OP. I indeed can understand that you chose to leave it “off”, but if you chose that state, then it has nothing to do with your original problem. So why you brought it up? (Rhetorical)
Whichever the case with Windows Defender, the questions in my previous post were still relevant and valid, and my suggested steps are too.
Please follow through with the Clean Uninstall of Avast under Windows Safe Mode and all the above steps, and report back.
