Dealing with the forcible insertion of advertisement in telecom hijacking

Recently in the page, when suddenly found an unknown AD, analysis issued now page inserted an ad code

Http://t.5txs.cn/rb/i8.js

All kinds of processing can not avoid being hijacked, finally there is no way, had to open this JS view, found that it calls Getelementbytagname to, and then inserted in the head inside the script ad fragment. So, rewrite it again.

Document.getelementbytagname=function (a) {return null;}

So, disgusting hijacking ads bye ~
