  • E-mail virus protection system and method
    Patent number: 7506155
    Abstract: A network is protected from e-mail viruses through the use of a sacrificial server. Any executable programs or other suspicious parts of incoming e-mail messages are forwarded to a sacrificial server, where they are converted to non-executable format such as Adobe Acrobat PDF and sent to the recipient. The sacrificial server is then checked for virus activity. After the execution is completed, the sacrificial server is rebooted.
