Thanks Essex. You guys are great.
"Are you still getting the flash update popup ? " Yes
“If so then go ahead and reset the router to factory”
Did that (several times) and it didn’t solve anything.
By the way, the Router Firewall has always been active and it’s admin has always been password protected. Immediately after setting up and factory resets I change that password.
One point about the last scans by OTL. Windows threw up an error message that there was a critical error and it said it would reboot in one minute without chance of postponing. I assumed that was the reboot you mentioned.
How long would that OTL Run Fix be expected to take? Is it a matter of several hours?
