• Someone who has your email address stored somewhere on her or his computer, becomes infected by a worm that uses spoofing.
• The worm searches for email addresses on the infected computer and sends itself to them.
• The worm inserts one of the email addresses it finds in the "From:" field of the virus emails it sends. In other words, it may use your address in the "From:" field, which tricks unwary recipients into thinking that the virus came from your computer.
