    Hello chl5235,

    Yes, we usually recommend installing the latest version. If you had BitDefender installed previously, make sure to run the uninstall tool from here

    The proper install kit for BitDefender Total Security 2011 can be downloaded from here

    Let me know if you have any other questions.
