There is a very good chance you are not infected. Netsky spoofs the senders address so when the e-mail hits a gateway scanning system and finds the virus, it sends a notification back to the sender to let them know. Geeezz I wish admins would turn this function off. With all the viruses that are spoofing address, notifications are becoming more of a pain than a help. I repeat, there is a very good chance your not infected if you keep your AV up to date, your address has just been spoofed thats all.
