Okay, I turned off uBlock and reloaded and clicked a few different pages. It took about 5 clicks to get the bogus patch to pop-up again. It first blanks the screen when it pops up, so there's just no way to see what it's doing. I also had Windows Defender pop-up at the same time and tell me it found Malware. The Kovter Trojan Category: Trojan Description: This program is dangerous and executes commands from an attacker. Recommended action: Remove this software immediately.

Hopefully it tells you something.
