    If you have Norton, McAfee, Microsoft Security Essentials, AVG, etc installed, they will disable the Defender by purpose.

    Read about Defender:

    http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Defender-on-or-off

    Enable or disable the Windows Defender

    When Windows Defender is on, you're alerted when spyware and other potentially unwanted software attempts to settle, run on your computer, or change important Windows settings. If you use the default settings, Windows Defender will also check for new definitions, regularly search for spyware and other potentially unwanted software, and automatically remove any detected item that has a recommended removal action.

    1. Open Windows Defender by clicking on the button start , clicking all programs, and then click Windows Defender.

    2. Click on tools and then click Options.

    3. Under the administrator options, select or clear the check box use Windows Defender and then click Save. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    Hello lovely2040,

    Thank you for using the Microsoft Answers forums.  I suggest that you use the System File Checker tool.  To use the tool (SFC.exe) System File Checker.   To do this, follow these steps:

    1. open an elevated command prompt. To do this, clickStart, click principally made programs, accessories, right-click Guest, and then click Run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click on allow.

    2. type the following command and press ENTER:

    sfc/scannow

    The sfc/scannow command. analyzes all protected system files and replaces incorrect versions with appropriate Microsoft versions.

  • Unable to turn on Windows Defender error: 0x800106ba.

    Original title: windows defender error.

    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.
