Can open Windows Defender

When I try to open Windows Defender it says it's off, and when I click on "Activate and open" it just does not respond. Any ideas?

When I try to open Windows Defender it says it's off, and when I click on "Activate and open" it just does not respond. Any ideas?

If you have one of the following antivirus installed programs, then what is happening is normal.

MSE - Microsoft Security Essentials
AVG
McAfee
Norton

Anti-virus programs have their own advocates, with 2 defenders running in the same will to computer to create conflicts. Therefore, they will stop Windows Defender.
There is nothing to worry about.

If you don't have one of those installed, then here is a way to reactivate it:

Start button > in the search box, typeServices > press the Enter key > scroll to find Windows Defender, click on it >...
topic status , it must be said... Has begun
under Startup Type, it must be said... Automatic
If it does not say that, right click on Windows Defender > click Properties >
in Startup Type, click on the pointer to the right and select automatic
to the service status, click Start
Click OK when finished.

    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; basically to have something very similar to the built-in Defender, and both running at a time will be your performance level and create the risk of problems that are contrary to the other.

    Thank you

    Help, please. trying to open windows Defender, but nothing works. also, what is the best way to get rid of trojans and other horrible virus. I'm learning the basics of computers so I would appreciate comments that includes technical jargon.

    Thank you

    I'll make this real short (for some it could be true long)...

    Question #1:
    Did you receive a warning message that your Windows Defender does NOT work?
    If the answer is Yes, thanks for posting this message, Word by Word. Then go to Question #2.

    Question #2:
    You have an antivirus (AV) programs installed?
    Norton
    McAfee
    AVG
    Microsoft Security Essentials
    If the answer is Yes, then you do NOT have a problem. The AVs have their own advocates, so they close Windows Defender. Raison d'etre: have 2 defenders at the same time will create conflicts.

    If you have NOT the above installed AV, then here's a way to re - turn on Windows Defender...

    Start button > in the search box, type Services > press the Enter key > scroll to find Windows Defender, click on it >...
    topic status , it must be said... Has begun
    under Startup Type, it must be said... Automatic
    If it does not say that, right click on Windows Defender > click Properties > in the new window, make the necessary changes, as above > click OK when finished.

    For the benefits of others looking for answers, please mark as answer suggestion if it solves your problem.

  • Publish with windows defender - error code 800106ba when I try to open Windows Defender

    I use windows vista sp2 32 bit op system.
    Windows Defender is set to automatic. but when I try to open windows defender, I get an error code 800106ba
    Please notify hw to enable this feature for protection.

    If you use another program (other than MSE) AV, Windows Defender may also be disabled. Examples of these other programs include but are not necessarily limited to: AVG, Kaspersky, Norton, McAfee, and Trend Micro.

    Hi the ball

    Kaspersky does not automatically turn off Windows Defender. However, it is recommended that, as usual, Windows Defender real-time protection is not enabled when Kaspersky is installed. Its a similar situation with Windows and Kaspersky firewall products that have built in firewall.

    I used Kaspersky products for several years and it has always been the case in my experience. I just tested with Kaspersky Internet Security 2012 race and I was luckily allowed to activate the protection in real time of the defenders of Windows and the Windows Firewall.

    I hope this helps.  :)

    When I try to put in operation and open Windows Defender I get one of the following errors: 0x800705b4, 0x800106ba, 0x800710dd.  What is the solution?

    You have the MSE, Microsoft Security Essentials, AVG, Norton or McAfee installed?
    If so, these programs are supposed to close Windows Defender.
    This is because they have their own advocates. 2 defenders running on the same computer is redundanr as well as to create conflicts.
    In short, if you have one of the above, you don't need Windows Defender.

    Is there another reason you want to open Windows Defender?

    P.S. Wrong forum for your question. He should go to the security forum.

    Hello

    You should try the following steps:

    • Manually start the Security Center Service

    Click Start, click Run, type "services.msc". Scroll down and double-click Security Center. Set starts off in automatic. Click on 'start. Restart your computer and check if it is running.

    • Manually launch the .exe

    Right click and "run as Administrator" on C:\Program Files\Windows Defender\MSASCui.exe

    • Registry

    Look for the value DisableAntiSpyware at:

    HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows Defender and delete who appreciate, but make a backup first.

    • Make sure you have a file named "wscui.cpl" in the Windows\system32 folder. If so, try to start, if not, you can copy it from another PC.

    Perhaps all this steps work for you.
