    Windows Defender will not start or run

    An interesting error occurred on my desktop with the Vista 64 bit during the
    first part of December '07.

    For the first time since Vista was loaded (about 1 October) I thought that I
    would start Windows Defender and scan the computer. This would be the first
    time in over two months. I got the following message:
    -----------------------------------------
    Windows Defender ---
    Application failed to initialize: 0x800106ba. A problem caused this
    program's service to stop. To start the service, restart your computer or
    search Help and Support for how to start a service manually.
    -----------------------------------------
    So I rebooted. Got the same message. So I went to the various places on
    the internet trying to find a solution to start Defender. None have worked
    so far. There were a lot of threads on XP, but I only found one on Vista.

    I even uninstalled MS Update <KB931099>, which was suppose to be a complete
    new Win Defender install and then reinstalled it again (with a reboot in
    between). No soap either with this change. Everything works OK on the
    desktop so I have gave up to find a solution at that time.

    I checked my laptop (Vista 32 bit) and defender works as it should. I could
    always go back to the repair of Vista on the desktop and I might do that
    sometime in the future. Any help or comments would be appreciated.

    Thanks!

    Re: Windows Defender will not start or run

    are you running Microsoft OneCare?
    If so, windows defender is turned off in One Care because One Care has its
    one built in WD.
    Some people had a problem after the last MS update.
    I personally do not use OneCare because of all its problems.

    No answers yet nor have I found a solution. I am not going to reinstall the
    Vista since everything else works and works well.

    Re: Windows Defender will not start or run

    Don't know whether this will help you or not, but I have a post open on
    similar lines see post "Win Defender non start?"

    For some reason, don't ask me why, but my defender is now starting 8 times
    out of 10 (I'm logging it) after I re-checked some of the option boxes, see
    my post. On the non start occasions, I am manually starting with no issues. I
    still don't understand why though the security centre is not giving warnings.
    Be interested to know if this helps you though!

    RE: Windows Defender will not start or run

    I had same problem. Fixed by going to control pannel-administrative tools -
    services - select Windows Defender-right click for properties-choose startup
    options and select automatic. Restart and no problems since.
