In Windows Security , Virus and Threat protection, "checking for updates". It scrolls and errors out (over 45 minutes now). Windows Update errors out with a 0x80070426; Troubleshooter errors out with the same code. Can't download Avast or any other virus scan that I've tried on Edge. Was able to download AVG in Chrome, but setup just scrolls and hasn't completed (20 minutes). Yesterday I did an update to Microsoft Edge. I'm waiting for the security update to time out so I can confirm the error code(never timed out, closed with no error code). I tried to dismiss the security update and it doesn't respond. Trying to update version 1.331.40.0 created 02/02 last update 02/02.
