 This joke email claims to be authored by the Amish or other similar low-technology populations who have no computers, programming skills or electricity to create viruses and thus ask users to delete their own hard drive contents manually after forwarding the message to their friends.The Tuxissa virus is another parody of the virus hoax, based on the concept of the Melissa virus, but with its aim of installing Linux on the victim's computer without the owner's permission.The story says that it was spread via e-mail, contained in a message titled "Important Message About Windows Security".
