Problem with "Sites block"

Hi, I’m trying to block this site but nothing worked for me. The site is:
https://check2push.com/notifications/push/cpm/1/index.html?subid_short=6343c0d3ada6d567808e57f8cd046738&p1=https%3A%2F%2Fzme8o3l1c4.com%2Fbbuksw2n%3Fkey%3D4495b037ca8e6d310b124eb8262de409

Is an advertisement page that I can’t block. I open the html sourcecode and I saw taht there is a javascript that change the URL of the page (or something like that). Unfortunately I’m not too able to solve this problem.
