Disable Windows Defender for Microsoft Vista

Windows Defender :: Vista Windows Defender is a free Spyware/Malware active scanner Microsoft shipped with their latest client Operating System, Windows Vista (you can download here for XP). Vista enables Windows Defender by default, which is OK unless you’re using another product like Spybot (my fav). Recently in my forum, a user asked How To Disable Windows Defender, so I figured it would make a helpful How-To write-up. Just follow the simple steps below.

 

Disable Windows Defender:

1. Double Click on the Windows Defender Icon in your Taskbar

Disable Windows Defender Vista

1a. Another simple way to open Windows Defender is to: Click the Windows Start button and Type Defender in the Start Search Text box then Press the Enter key.

 

2. Click Tools then Click Options

Disable Windows Defender Vista

 

3. Scroll to the bottom of the Options and uncheck the box Use Windows Defender. Click Save to exit and save changes

Disable Windows Defender Vista

 

4. Click Close

Disable Windows Defender Vista

 

Now for most users, this should be sufficient to disable Windows Defender. There is, however, another step you can take to remove Windows Defender from your system startup.  Feel free to take a look now at this groovy How To article.

    @Roel Piedad – Welcome to the site!

    One last thing you could try is disabling the Defender Service. To do this, Check out this article I just wrote: http://www.groovypost.com/howto/microsoft/vista/disable-windows-defender-service-in-windows-server-2008-or-vista/

    Looking back, this is probably the best way to disable the Windows Defender Service. Hopefully this fixes your problem.

    I recently purchased a new laptop HP G60-115EA/EM. As usual with all new computers you want it to be secure, so i purchased Sophos Anti-Virus and McAfee SecurityCentre. Now everytime I startup my laptop, an error message comes up. The error message says:
    “Application failed to initialize: 0x80010ba. A problem caused Windows Defender service to stop. To start the service, restart computer or search help and support on how to start a service manually.”
    it would be greatly appreciated if anyone could offer any assistance .

    Regards

          @Joe,
          Go into the forum – http://www.groovypost.com/forum/ and create a topic in the Vista forum. Take a screenshot of your options page and attach it to the new topic you create so I can see what were dealing with.
