    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
    performance and create the risk of problems that are contrary to each
    others.

    I get an error of windows defender, 0x800106ba, whatever that means?  I am not able to turn on the Defender because of this error...

    What other security programs you have running? Many as MSE, Norton, McAfee, AVG, etc., will stop Windows Defender because they have the same functionality, and having two programs running at the same time and make security the same work can lead to conflicts. This is by design and must be accepted by the user.
