What is it that you can’t do - I’m taking a bit of a swing at this, you don’t want to update to the latest version ?
If that is correct then the above suggestion won’t stop it notifying you that a new program version is available.
That would be avastUI > Settings > Update - scroll down to Program and click the Settings (blue text). Setting it to manual update should normally stop you getting the notifications.
More importantly knowing why you can’t do this, may help us to overcome the problem in updating.
