Does anyone know who [email protected] is?

If you do, please tell her (him?) that she has a virus on her machine. It sends copies of itself, as attachments, to people in her address book. The messages have false headers, making them appear to come from OTHER people in her address book.

If you get a message with an attachment that you are not totally sure of, DO NOT open it - this is how it infects your machine.

You can also check the "return path" on any such document. How you do this varies from one ISP to another. If you check a message, and find that the return path is different from the name in the "From:" line in the message header, that's a pretty good indication that it is this virus.
