I ran the Avast Repair for 1 and 1/2 hours - nothing happened. I rebooted to stop the Repair Function.
When the computer rebooted - up came a notice to update the Avast VPN app. So I did. and Rebooted again.
When I did, I went to Avenue Anti-Virus and the continuous loop on the updating of the Virus Definitions had stopped and I was able to get it to update to the latest Virus Definition.
Thanks.....
