McAfee VirusScan Plus 2007 Conflict with Norton. Help!!

Hello Everyone,

I am trying to install McAfee VirusScan Plus 2007 on my Windows XP machine. Each time I get an error saying it can't install because of Norton Rescue Disk and Norton Antivirus 2002 Professional Edition.

I have never installed these items so they must have come with this computer (Dell Dimension). I uninstalled everything I could but am still getting the error.

Here is what I have done so far:

*Uninstalled Norton
*Went to the Norton website and used the removal tool to get rid of anything Norton leaves behind.
*Removed all Norton/Symantec folders and files.
*Went into the Regedit and got rid of everything Norton/Symantec
*Also tried booting into Safe Mode to get rid of everything.
*ran all my spyware products.
*Went to the McAfee help site and they cant' help me because it is a Norton product.
*Went to Norton and they don't have anything relating to products from 2002.

So, how on EARTH do I get rid of this? I want to install my software.

Much much thanks in advance.

I really need to get rid of this program. Also, I can not reinstall XP because it didn't come with this Dell.
