Once you have made a succesful virus, and have the world at your feet (as those jerks may feel), it´s very easy to start new ones with different names and different legends to hook the curiosity of people. Again, destroy those mails as soon as you see them. Don´t even try to reply to the sender. Don´t open unsolicited attachments coming from your mother. Sure it is not a sweater.
