• The reactivation of Windows Defender in Windows 8

  Hi all

  This is my first time here, so please bear with me.

  I bot a desktop HP Pavilion yesterday and everything was going well until I tried to turn on WINDOWS DEFENDER. The message is "Windows Defender disabled by seller". I don't want to use any other anti-virus, anti-blah... blah package since I was an all-things-Microsoft kind of guy. Anyway, how can I go abt turning Windows Defender powered? I really, really appreciate anyone who can help me on this one.

  Yes, you need to uninstall "Norton Internet Security", following the steps you provided. I said "disable and uninstall", this is because many AV programs won't let you unistall them while they are active.

  To reactivate Windows Defender, go to the new Windows 8 desktop and type 'Action', click on 'Settings', and click on "Action Center"... check the status of Windows Defender and click the button "turn on Now". Update definitions for Windows Defender... and then do a full scan.

• Windows Defender appears each time computer is turned on

  Everytime I turn on my computer windows defender appears saying that it is turned off. Windows Defender, I opened and he was selected to be marketed. So I checked the box that said turn on windows Defender but whenever I have turn off the computer or restart it, it says that windows defender is stopped. Why this is happening and what can do?

  Hi Babyblues221,

  From your description, it seems plausible that another program can be disable Windows Defender.  You use a different type of antivirus/security software?  These are often the causes of Windows Defender turned off.  You can try a "clean boot" to verify that it is or is not caused by another application.  To check this, reactivate Windows Defender, follow these steps:

  To perform a clean boot on a computer that is running Windows Vista, follow these steps.

  1. Click on launch , t
  2. Type msconfig in the box start looking for and then press ENTER.
     
  • If you are prompted for an administrator password or a confirmation, type the password, or click on continue.
  • On the the general tab, click on Selective startup.
  • Under Selective startup, turn it off box load startup items.
  • Click on the Services tab, select him hide all Microsoft Services check box and then click on Disable all.
  • Click on OK.
  • When you are prompted, click on restart.
  • After the computer starts, start the program or game and see if the problem is resolved.
    If Windows Defender is on, there is another program that starts and stops this return.  You may need to try to reactivate each non-Microsoft service individually to find the app problem.
  • Some services may temporarily lose functionality when you perform a clean boot procedure. When you restore the settings, the functionality will be restored. However, the original error message or behavior may return.
  • Be aware that if the computer is connected to a network, network policy settings may prevent you from complete the clean boot procedure. You may need to contact the aid system administrator if you cannot perform a clean boot.

  I hope this helps!

  Hi Mitchjr,

  ·          You have databases of security of Microsoft or Windows live OneCare software installed on the computer?

  If you have two Microsoft Security databases or Windows live OneCare software installed on the computer, you will not be able to install Windows defender on the computer. You will need to uninstall them or do not install Windows defender on the computer.

  If you don't have Microsoft Security Essentials or Windows live OneCare software installed on the computer then you will need temporary deactivation of security software installed on the computer and then try to install Windows defender.

  No Norton, AVG, Windows Security Essentials etc etc? None?

  You go and install Windows Defender. It comes with the system, its share of the operating system. It can not be uninstalled either.

  Now, the question:
  What exactly do you say 'Windows Defender is gone'?
  What makes you think it went?

  3. open administrative tools

  However, once there, there's no option to choose Windows Defender or ONE of my startup programs. Furthermore, when I tried of all this that I made right click has a drop down menu that says:

  1 Explorer (which showed only the administrative programs/apps tools)

  4 News (which allows me to create a new folder or briefcase in administrative tools)

• Windows Defender does not work. When I try to turn it on, I get the message "not responding".

  Original title: Windows Defender

  I have Windows Vista and my Windows Defender will activate/doesn't not work.  When I try to turn it on, it responds by saying: 'it is not responding' and stops automatically.  I tried to re - install & who did not work.  Any ideas.

  Hi lskdjfoie,
   
  What have you tried to reinstall? Windows Defender or other programs?
   
  I suggest the following steps and check.
   
  Step 1:
   
  Usually if you have a third-party security software installed, Windows Defender would not work. I would temporarily disable all security software and check if the problem persists.
   
  http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Firewall-on-or-off
  
  http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software
   
  Note: Antivirus software can help protect your computer against viruses and other security threats.  In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.
   
  Step 2:
   
  If this does not help, I would say you scan SFC on your computer and check if Windows Defender works fine.
   
  Step 3:
   
  If none of the steps helps create a new user account and check if the problem persists.

• Windows Defender Software Explorer to allow a program that I have disabled.

  I was able to use the Windows Defender Software Explorer to DISABLE a startup program.  The program was DELL QUICKSET.  Now I would like to REACTIVATE the same program, but when I select, all three buttons, DISABLE, ENABLE, and REMOVE stay gray.

  I have the same program for the 4 other programs that I have disabled grayed out, I select and buttons are still grayed out, although earlier, I was able to use the same method to disable gthem.

  You cannot use Autoruns to disable programs, just control those who start or do not start at startup (if they were added by the program, or Vista).  I don't know why Software Explorer does not activate the ptorgrams - should be because this is the program that the disabled.  Maybe it's an update or some type of permissions (or problem of corruption in the program that cannot be uninstalled or re-installed on Vista without a Vista in its entirety.

  We will try this.  Go to C:\Program Data\ Microsoft\Windows Defender\Software off Explorers\ items in the startup folder.  Check the list for the item you want to activate (it should be here as disabled).  Try to delete or otherwise remove this item from the folder.  If necessary, try to right click on the element, and then click Run as administrator (if this option is available).  If not, right-click on the item and click Properties, then security and give you all the rights and ownership (you will have to do it for the folder itself, or perhaps even its parent folder as well or as high as necessary to obtain permissions and ownership).

  If this does not work, try to use one of the following free products to remove the file...  Unlocker to:http://www.softpedia.com/get/System/System-Miscellaneous/Unlocker.shtml or file Assassin http://www.malwarebytes.org/fileassassin.php (with or without forcing the deletion: http://www.mydigitallife.info/2008/12/27/force-delete-cannot-delete-locked-or-in-used-files-or-folders-with-fileassassin/). These programs often work when normal functions remove Vista not work correctly.

  If this does not work, try to uninstall the program and reinstall again (if you have the software or you can get it from the manufacturer's web site)., Dell is good enough to make available software downloads.

  If this does not work, try Windows Defender Discussion Group at:http://www.microsoft.com/athome/security/spyware/software/newsgroups/reader/default.mspx?dg=microsoft.private.security.spyware.general&lang=en&cr=US&r=33d293cc-19b6-404b-865b-565a73822c7f where experts advocate may be able to solve your problem.
