PROBABLE NEW WORM ALERT Norton or McAfee not getting it HELP

[ThomasStraten]

Hi,

Everyday, once or twice during the day, when I send 1 message only,
Norton Antivirus (SystemWorks 2002) shows a window "Sending message 1
of 2".

After a short while, i get a reply as follows:
DELIVERY STATUS NOTIFICATION

NOTES:
3Dtstraten is not me, obviously.
The sent message NEVER APPEARS in the sent box.
The FROM: in the file ATT0040.txt states clearly that I sent the
message (which is false)
Neither Norton, Spybot, McAfee, PestPatrol are able to find something
wrong with my computer....
Subject varies from message to message...

It is driving me crazy!!!!

How could I check my computer (XP Pro Service Pack 2) OUTLOOK XP to
find what is going on....

I even use my DTSearch Forensic software to check for something
suspicious:nothing!!!!

Thanks

Thomas
