How can I get my computer to keep going to the myaccounts.nationalcity.com?

I emailed you last week with this question and you suggested to download anti-spyware, which I did and it did not remedy the problem. Any other suggestions on how to keep my computer from allowing this webpage https://myaccounts.nationalcity.com/m/apps/psaver/yps_ver to pop up 50+ times would be greatly appreciated.
