For me it came up when the scan had completed giving me options on what action to take, two I said to delete as I knew what they were and one I told to do nothing.

The notifications screen is accessed by clicking the Bell icon on the top right of the main avastUI page (normally it will have a number superimposed over it, to say how many issues there are). Clicking it after having taken the actions (Resolving) you won’t see them again as the last action essentially clears them.

Edit: added image.
