Windows Defender. failed to initialize 0x800106ba

a problem caused the stop of the programme service. How to start this service?

This problem can occur because another security application is used or the Windows Defender service has stopped, or components of Windows Defender are corrupt.

You install any new programs recently? Windows Defender is not designed to protect against the extent of malware. If programs like Microsoft Security Essentials and Windows Defender both run, your system may experience degradation in performance and other problems caused by the conflict of two services providing real-time protection at the same time. I recommend that you keep the Defender off if another application of security protection is running.

If no similar security application is installed, I suggest that we have follow these steps to resolve the problem:

Step 1: Check the Windows Defender service
=================================
1. click on start, in the search box, type: "services.msc" (without the quotes) and press ENTER. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
2. double-click on the service "Windows Defender".
3. click on the 'general' tab. Make sure the "Startup Type" is "automatic". Then please click on "Start" under "Status of Service" to start the service.

If the problem is not resolved, please refer to step 2:

Step 2: Save the associated DLL files
========================
1. click on start, type "cmd" (without the quotes) in the box start the search. Right click on CMD listed above and click 'run as administrator '.

2. in the command prompt, type the following and press ENTER to each order:

regsvr32 atl.dll

regsvr32 c:\windows\system32\wuapi.dll
regsvr32 softpub.dll
regsvr32 mssip32.dll

3. close the command prompt, and then run Windows Defender.

    Hi torobull,

    Looks like you may have a virus.

    If a virus infects a computer, it often blocks the ability of the computer to run antivirus programs or causes these ineffective programs. Follow these steps to control and eradicate any viruses:

    1.

    If you do not have an installed antivirus program, you can use the Windows Live safety scanner, or install an another antivirus scanner. You will need to do this before you follow the next step.

    2.

    Restart your computer in safe mode. For more information, see start your computer in safe mode .

    3.

    Scan your computer for viruses. Go online and read Live OneCare Safety Scanner"" href = "http://go.microsoft.com/fwlink/?LinkId=143630" > how to install the free Windows Live OneCare Safety Scanner

    For more information.

    Notes

    • Scanning your computer can take time, and your computer may appear to be frozen or inactive. Allow scanning completed successfully before you continue.
    • Each antivirus program scans and removes viruses differently. Review of your anti-virus help or documentation for specific instructions.

    4.

    Once you've scanned and removed any viruses, restart your computer.

      To restart services required by Windows Update

    Open administrative tools by clicking the Start button, click Control Panel, clicking system and Maintenance, and then clicking Administrative Tools.

    Double-click Services.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    3.

    In the Services window, double-click in the Background Intelligent Transfer Service.

    4.

    Under the tab general , under Startup type, click Manual, and then click apply.

    5.

    Click the connection tab and make sure that the service is enabled in every hardware profile listed.

    6.

    Click the general tab, click Start, and then click OK.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    7.

    In the Services window, double-click Windows event log.

    8.

    Under the tab general , next to Startup type, make sure that Automatic is selected.

    9.

    Next to Service status, check whether the service is started. If not, click Start, and then click OK.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    10.

    In the Services window, double-click the Windows Update service.

    11.

    Under the tab general , next to Startup type, make sure that Automatic is selected.

    12.

    Next to Service status, check if the drive is listed. If not, click Start, and then click OK.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    13.

    15.

    16.

    Close the Services window and try to install Windows updates again.

    Here are some other options for scanning of your PC.  No one program can catch them all.

    It has no product called Windows Security. Do you mean Microsoft

    If you mean that Microsoft Security Essentials, it turns off Windows
