Pop up

[rayjay]

OK, the pop up problem has been solved with the Adblock Plus.
HOWEVER, I have a PITA problem with spybot as I uninstalled it to return to using my Norton, now Bitdefender, and ever since, whenever I boot up the computer I get a pop up from Spybot "Post Windows 10 upgrade re-installer for Spybot-Search and Destroy". I then deleted the Spybot folder in Programs but again it still pops up.
Now my googling has found I need to delete this from Registery Editor so I google how to do that, clicking on HKEY CURRENT USER and then Software, but can't find a Spybot folder to find what needs deleting.
Can anyone help me remove this?
It's just my luck, fix one thing, end up with another.
