Cannot activate Windows defender error 0x800106ba

original title: Windows defender

When I click on windows defender in control panel it States it is turned off and when I Flash similar to turn on windows Defender, the following error message: Windows defender encounters the following error: 0x800106ba.  Please help me in this regard.

First of all, what AV program do you use?  Several intentionally disable Defender during installation to prevent conflicts - what could be normal and not a problem.

If this isn't the case, then check the following thread where at least 3 different solutions are available for exactly the same error message with the Defender:http://social.technet.microsoft.com/Forums/en-US/itprovistaapps/thread/f5536f2d-aceb-41a5-beb6-92e5d3b2f73f.  Maybe we'll solve your problem.

I hope this helps.  If this isn't the case, post back with the results of what you have tried and your current AV program and we'll see what we can try.

Good luck!

    Yes, that's why. Microsoft Security Essentials, AVG, Norton, and
    McAfee all turn them off Defender. It's good, not bad. Not only is at - it
    potential conflict, but there is no reason to have both. they are all
    basically have something very similar to the built-in Defender.
    and both running at once will be your performance level and create the
    risk of problems that are contrary to each other.

    also try to stop a web sight to come whenever I start the computer. Cannot delete because the Defender is not on.

    It is not correct that you can't remove it without defender. Use
    MSCONFIG, which is part of Windows.

    You are running Microsoft Security Essentials, AVG, Norton or McAfee?
    If you run one of those, she didn't have Defender. It's
    good, not bad. Not only is there potential conflict, but there is no
    reason to have both; essentially, they have something very similar
    for the Defender integrated and running both at once will hurt your
