How did this javascript get into all code on the web server?

[Mr.Dave]

Does anyone what the heck this code is used for? It got inserted into all code on the webserver and cuts off the bottom portion of the code when you view the sourcecode or download the file.
----------------------------------------------
<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>
---------------------------------------------
onLoad="var SymTmpWinOpen = window.open; window.open = SymWinOpen; window.open = SymTmpWinOpen;"

Thanks,
Dave

Hi Dave!

I had the same problem and I figured out, that Norton Internet
Security 2003 is responsible for that. When the firewall is
deactivated, the script is not inserted.
The script is inserted in EVERY HTML Page you load via http. This
affects not only local pages. Unfortunately I don't know whether this
'feature' can be disabled without deactivating the firewall itself.

Hope this helps!
