Is there a way to turn off Alerts when a scan completes for Endpoints? That information is not very important. It should only alert when an Endpoint is past due for a scan.
You are right, and it is annoying; however there is no way to do anything about this in 9.00x ... word is that 9.100 (soon to be in beta) will revamp the endpoint management admin experience, I'm sure they'll be addressing this.
