Pop up

[rayjay]

The computer has been totally reset with windows 10 reinstalled, without anything I had previously installed, just like a new computer.
The pop up comes in behind the Chrome page I view on, but I know when it comes up because it has sound to start with and in my task bar, I can see a second icon behind the chrome icon of the page I'm viewing.
Before the reset, I had Norton check out the computer as the Norton full scan didn't pick up anything to cause this, and, I didn't know any other way to be sure it wasn't something loaded on my computer, even though they told me there was nothing they could find when they took control of the computer to check themselves.
As I said though, it ONLY pops up at times, and ONLY when clicking on the Canreef link.
