1.Make a backup of your registry before you begin. Proceed with these instructions only if you are confident about what you are doing.

2.Click Start > Run.
3.Type regedit and press Enter. This will open Registry Editor.
4.Double-click HKEY_LOCAL_MACHINE > SOFTWARE.
5.Locate the McAfee registry key and the Network Associates registry key. You may have one or both of these.
6.Expand the McAfee and Network Associates registry keys to inspect their contents and sub-keys.

 If you have McAfee or Network Associates software installed on your computer apart from McAfee VirusScan and McAfee ePO, then you should use caution when considering whether or not you want to delete these registry keys. If you delete these registry keys, you may find that other McAfee or Network Associates software no longer functions as expected. If you are sure that you do not have any additional McAfee or Network Associates software installed, delete the McAfee registry key and the Network Associates registry key.
