A self-destructing document or e-mail messaging system is provided that automatically destroys documents or e-mail messages at a predetermined time by attaching a macro or virus to the document or e-mail message. A macro is created (220) and is attached (230) to file such as an e-mail message (280) or document (270) when it is created. The macro contains a portion of executable code or an executable program which instructs the computer to overwrite and/or delete the file to which the virus is attached at a desired time.
