How do I stop McAfee anti virus from sending these pop ups?

I used to have McAfee anti-virus but switched to Norton right after they charged me for more than I had been paying. But they would not refund my money. Ever since then they have been sending me emails saying I had been charged for renewal, even though no charges were ever on my card. Now they are sending pop ups saying I have a virus and blah blah. Norton says everything is find and my Window security says no action needed. These stupid pop ups come on every 10 minutes. How do I stop them? I'm pretty sure my pop-up blocker is on yet these bypass it. Help!

I've noticed that all these pop ups are from Flowrating. com and that I heard they are an unsafe site.
