JavaScript code (SymError, etc) added to page when uplaoding to server

[Snookerman]

Hey

Every time I load a page to a server and then view the source code, there is some JavaScript code that I didn't write myself, it was just added.

I have always had this and it didn't bother me since I thought it was normal, but I noticed that many pages don't have it, so there must be something with mine.

There is a piece of code added to the head section and one after the html closing tag. They look like this:

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

function SymError()
{
  return true;
}

window.onerror = SymError;

function SymInitWinOpen()
{
  if (SymRealWinOpen == null)
     SymRealWinOpen = window.open;
  return SymWinOpen;
}

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

var SymRealWinOpen;
window.open = SymInitWinOpen();

//-->
</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;
  if (SymRealOnUnload == null)
  {
     SymRealOnUnload = window.onunload;
     window.onunload = SymOnUnload;
  }
}

function SymInitWinOnload()
{
  if ( SymRealOnLoad == null )
     SymRealOnLoad = window.onload;
   return SymOnLoad;
}

window.onload = SymInitWinOnload();

//-->
</script>

Id doesn't seem to appear when I validate the code but it's there if I view the source or save the page.

What I'd like to know is: What is it? Why does it appear? What does it do? Do I need it? If no, how do I get rid of it?

Thanks for your help!

Yahoo servers write some script to pages. Do you have your own server or are you using one? In a yahoo page I worked on the code didn't show up when I edited just when I hit view source on the live page. It did say it came from the server but maybe you have a different one that doesnt?

I've seen this on pretty much all the pages I've written so far. I've used mostly web servers (one.com, 110mb.com, etc) and also local servers (municipality server). It happens when I upload with IE's ftp, with most popular FTP:s and with 110mb:s file manager. From what I've seen so far, it's not dependent on the server or the ftp service so I'm guessing it's my computer. I run XP sp3 and I have Norton 360:s firewall.

Oh, by the way, I see this code when I view DD:s or Google's source code as well.

You're running Norton Internet Security. Norton likes to insert such things into downloaded pages.

You're right, it's Norton:

Apparently, it's needed for the ad blocking and can be avoided by turning off the ad blocker. They don't really say what it does, though, or if there's a way to get rid of it without turning off the ad blocker.

I think I'll just ignore it, I prefer getting rid of ads.
