I have searched the forums and found that quite a few sites have javascript popup ads when you press the next page. sceper.ws also does this, however, it appears to be somewhat at random. Sometimes it is page 2, or another page. It doesn't do it every time and on every page.
Here is one similar example
Here is one of the url's that pop up:
Code: Select all
javascript:window.opener=null;setTimeout(function(){window.location.href='http://onderlea.info/YkNtSlpdZRkjPl91WXtrUXNLOD8GflxsOwA3UHh8FH5cZGtSbVh+dFBlGHdiByVaeW5Xclp6YlVxWyg+W3dYeD5bc11/bVJyXXo5B2ULOWdTZQQsZ1JlHidnVnJLIWcbLBg4f1BzACUsCyYeb2hSMAUlLRFmX3o9Ay4IOX9QcwIkPwYnAW9oUjAOLzQHZl96Ow43CDg0AzcEPD9HcV04NhEvAi18ECYLdzIWNx1vaSNmXwx/UAUeKT8SJh9kLRFmXwwqAyQIb2gkcUspLl9ySykuAX5abCkWMFB7fA0wH3cpASYdLyhMNB5sKhAtUHp8'},250)
