If the "4 out of 5" bothers you and you don't have Outlook, why not just remove that provider (and/or any others you never use, like P2P in my case)?
Go into add/remove programs, select "Avast" then "Change", and you'll see among other features all the resident providers. Just untick the "useless" (for you) ones and save your changes.
I don't know if it's still the case, with recent program updates which have improved shutdown times generally, but at one time it seemed to be agreed that system-shutdown time could be improved a little with fewer providers.
(Edit) As a P.S., if at any time in the future you find you do need the removed providers after all, they're easily replaced the same way you took them out.
