I tried to send you a reply to your question, but you have your anti-spamming program on and the answer to your question came back non-deliverable. Hahaha worm does not need to be sent as an attachment. Once on your hard drive it searches for message lists and can mail itself, it also can update itself from the Internet. So once yo send it out, and you wont know you have it, it can be sent to another person without your knowing it. That's how it was sent from one person on this list to me. It arrived as a separate message. It means someone on this list has an infected computer and sends it out each time the send a message, it could even be mine and the worm is sending itself back to me. Doyle Sanders Tulsa, OK
