OK, that certainly isn't normal, I wouldn't have thought there would be that information to gather. I have never seen this on either of my systems (it is almost instantaneous, I see the spinning circle for less than a second), but neither are low powered, etc. However both are Avast Free.
I'm just wondering if this isn't something related to having Avast Pro, e.g. is trying to update/convert to Avast Premium Security, as avast are trying to switch users over on to the Premium version (at no cost for the remainder of their license period).
Or that the Avast Pro Firewall is set to Public or somehow blocking a UI connection.
You could try an Avast Repair.
