ios 浏览器被嵌入弹出广告，抓不到脏怎么办呢？

未越狱的ios上用safari浏览网页每隔一段时间会出现一个弹出广告，很多网站都会出现。联机调试了网页内容如下：

头文件被嵌入了脚本：
<script src="http://google-adsense.frameshopyork.com/floatcenterupgamer.js?os=ios" type="text/Javascript"></script&g;

脚本在body页生成一个div层：
<div style="width: 240px; height: 180px; display: block; border: none; padding: 0px; background-image: none; z-index: 2147483647; position: fixed; top: 50%; left: 50%; margin-left: -120px; margin-top: -90px; background-position: initial initial; background-repeat: initial initial;"><div style="position: absolute; top: 0px; right: 0px; width: 36px; height: 36px; line-height: 36px; font-size: 36px; font-weight: bold; vertical-align: bottom; text-align: center; margin: 0px; padding: 0px; border: 0px solid red; z-index: 9; background-color: transparent; color: red; cursor: pointer; background-position: initial initial; background-repeat: initial initial;">×</div><a href="http://app.upgamer.com/down/addown.php?pl=ios" style="width: 240px; height: 180px; display: block;"><img src="http://app.upgamer.com/down/ad/poppic.png" style="width: 240px; height: 180px; border: none; margin: 0px; padding: 0px; display: block;"></a></div>
