There is no such thing as Service Pack 3 for Windows XP, or Windows
Vista, or Office 2003, or Outlook 2003, or Office 2007, or Outlook 2007.
So I ask again, what is "the XP SP 3" that you keep referencing?
And I ask again, what version of Norton? The thing about Norton
Antivirus is that it has a number of components. Turning off or
uninstalling the main antivirus component does not necessarily turn off
or uninstall some of the other components. A classic example of this is
Norton Antivirus' Microsoft Office Plugin, which can remain installed
and active until you explicitly use the Norton software interface to
turn off the plugin, or until you manually unregister the plugin's .dll
file in Windows if you uninstalled Norton. This is why I suggested that
you turn off the email scanning function in your antivirus application.
I did not suggest that you turn off your antivirus application, nor
did I suggest that you uninstall your antivirus application.
It seems a number of other people besides me have tried to help you.
And it seems you are not listening to the people who have tried to help
you, you are not following the instructions given by the people who have
tried to help you, you are doing what you feel like doing, and you
refuse to tell us what you are doing. If you really want other
suggestions, then here are two... I suggest you provide the specific
additional information requested by the people trying to help you, and I
suggest you stop wasting people's time and bandwidth asking for
suggestions if you are going to ignore those suggestions anyway.
