Ray, I appreciate your help. As I still do not understand how these viruses work, could you clarify for me? If I were going to send you a file of my Payne line, I would write you an E-mail and attach the file to it. You would read my message and decide whether to open the attached file. If I were the recipient of an automatic virus, would it attach to what I send you or would it capture your address and send its own attached file? Are you saying that it would come with a message that you would read to be sure it was from me? This is all so confusing! I know we have to be careful, and I certainly want to be, but I'm just not sure I know how. Anyway, thanks for your help Anne Nelson
