Thanks, How do I keep it from not popping up all the time?

Avoid whatever website you were visiting then they started to pop up. That site gets paid from the scammers, if you purchase whatever worthless tool they're telling you you need.

Next, Open the Settings App, go down to Apps at the bottom of the page, tap it and look for Safari. Tap there and scan down to Clear History and Website Data and tap that.

No. That’s a scam pop up.
