OK…so woke up this morning and watched all three machines do the SCAN…now set at Custom.
I opened up the DETAILS view and at completion sure enough…
“Avast Has Just Completed & It Specifies in Settings To Shutdown”
I clicked out of that and went in to each of the settings…the box to “shutdown” is not clicked and on one of the machines I had toggled prior. So, now I am going to try the REPAIR, also think I have a saved config file from a month ago I’lltry to restore.

Question…can I use a config file from one machine to another ?
They are all identical O/S and the settings are all the same.
