First, I’m an Avast user and not an Avast Team member, as are most of the respondents here.
Not entirely sure what these are from your information, but I suspect it may be promotions.
Avast in program ADs - see attached settings images, which may reduce them if my suspicions are correct.
- These are a fact of the free version, but can be removed in paid versions of Avast - AvastUI > Menu > Settings > General - Personal Privacy and you can uncheck them, ‘Show offers for other Avast Products’ and ‘Show offers for 3rd party products’.
- Also check the AvastUI > Menu > Settings > Notifications - Limited Mode.
