This java script is on all of my pages

I don't know how it's got there so can you help

[kar3n]

I have this code at the bottom of all of my pages but I haven't put it there and it isn't there until the page is uploaded. Does anyone have any ideas.
I recently read it's something to do with Norton which I have on my computer so maybe it's not doing any real harm hopefully.
here's the script

<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>

You can see it on the very bottom of the source code on my pages

Many thanks
Karen

Hello kar3n, Welcome to WebmasterWorld!

What you are seeing is your security software injecting its own JavaScript into the page before it loads in your browser. This is not something that is on your "actual page" but only appears there after it loads in your browser due to the security software you are using.

Changing your security settings would get rid of this code if you needed to. It is Norton's way of preventing malicious attacks on your system.

Hi

Wow. Thanks for the welcome and such a quick response too!

So it looks like I can put my mind at rest now then.

I hope this also helps anyone else who may see the same thing as well.

Many many thanks as I've been worried about all this stuff about hacking websites which I'm sure I've lots to learn about there.

This script redefines window.open and window.onunload, a method and event respectively.

By itself it doesn't seem like this script would do anything, since some of the objects (like SymRealWinOpen) are undefined. But I suspect this script is not acting in isolation.

I'd put this in the "harmless but annoying" category. If you're doing any serious custom javascript work, it could get in your way.
