thanks for the reply but:
So no Avast Premium Security (APS) in the Programs and Features, yet your second images shows it is installed.
This would appear to also be an issue with APS.
If you go into the Windows Security, Virus & Threat protection and check is ASP shown as the Antivirus protection ?
If not and other than the issue with real site, it appears to be working I would try an Avast Repair.
Avast UI > Menu > Settings > General Troubleshooting - APP Repair and restart after that.
Hopefully that will at least rectify ASP not showing in the Programs and Features and give the option to use the Change option to uncheck the Real Site component in ASB.
