Microsoft Outlook plug-in PGP version 7.0, 7.0.3, and 7.0.4 silently saves a decrypted copy of a message to hard disk when "Automatically decrypt/verify when opening messages" option is checked, "Always use Secure Viewer when decrypting" option is not checked, and the user replies to an encrypted message.
