Both my Comcast and gmail accounts received an email from "Tommy" which caused a suspicious never before seen popup to appear. I had been expecting something of this nature to occur because I made a joke about Marilyn Monroe taking over God's throne. In the movie there is a scene where Tommy is taken to a place where they worship Marilyn, and a hilarious scene follows whenhe overturns her statue...
My solution at the first on Comcast was to immediately do a reset my Safaribrowser. When a weird message popped up at gmail in the process of accessing the spam folder I reset Safari and powered down the machine.
If I am making a false alarm, then there is no harm done, but I suspect that the popup is to cause the user to enable master account privileges for the current account, with the bogus request to report error message substituting for the normal privilege requestor.
