Avast 14.3 Auto-updates and Notifications forced now?

I seem to have Avast 14.3 now. I disabled automatic updates because I use mobile hotspots whose data is expensive, auto-updates are still disabled, but it has updated itself anyway, and checks every few minutes.

14.3 seems to also have removed the silent mode, and is nagging me to delete cache, trash and temp files (like some cheesy 2016 Android ‘battery booster’ app).

Are these deliberate, permanent decisions Avast?

I take it you mean Avast Mac Security - in which case this should go in the Avast Mac Security forum.
