This is added to each page that I visit and it correpts some pages as my home page this is the only computer out of 3 that does it. Can you tell me what it does and where I might find the program that does it?

<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>

this is added at the bottom of the page...

<script language="JavaScript">
<!--

window.open = SymRealWinOpen;

//-->
</script>

Thanks for any help....
