Little pop up help

I have a problem with I.e and edge only started since latest Windows update if I open ie or edge then try to go to a site I get a little pop up on page saying do you want to leave this page. Click leave or stay does anyone know how to fix this thanks

I'm afraid this is the result of some malware. Try searching with Malwarebytes Antimalware. If you find too many malwares, I recommend using a second program, such as Spybot or Spyhunter to eliminate any malware not detected by Antimalware. Some malwares may try to stop the scanning, so I recommend installing the application, update it and then restart in Safe Mode to scan your system. Delete all the results found.

The thing I don't get its appearing on my PC and laptop and the only thing that has changed on both systems is Windows 10 update 1511 nothing else and I don't go on web sites I don't know and I have scanned both with malwarebytes and Microsoft malicious software removal tool and nothing Shows up
