Unwanted JavaScript

[Dolbo]

Hi folks,

I've posted a thread in CSS ("Weird stuff happening") which explains how some code is disappearing from my web pages when I view them at home.

I'm also getting the dual problem of getting unwanted JavaScript in my pages when I View Source:

This at the top of the page:

<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>

and this at the bottom:

<script language="JavaScript">
<!--
var SymRealOnLoad;
var SymRealOnUnload;

function SymOnUnload()
{
window.open = SymWinOpen;
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>

I didn't put this there! Any ideas why this is being rendered in my source?

This only happens when I view my pages at home - not on my work computer. When I pulled a page back off the ftp server to check whether this code is there it wasn't.

I'm stumped!

Any help is very gratefully accepted. Cheers.

I get that too. In my case it's added by Norton Internert Security.

It's Norton's Ad Blocking and popup stopper. Turning it off appears to be the only solution at the moment.

Problem solved......

....only been online for a few days and have more security than the Penatagon. Didn't think Norton were going to rewrite my pages though!

Thanks for your suggestions, it's appreciated.
