Avast Free Antivirus update modified its settings, without warning.
It showed an almost screen-filling diversion telling of the enhancements/merits of its latest updates.
It insists on turning OFF its “Passive Mode“. But then Microsoft Defender would be disabled.
It did NOT tell that it switched ON its automatic update, you have to dig for it to switch it off.
If you have Avast Free Antivirus, better check its settings for unanounced/unauthorised changes after updates.
