Disable Windows Defender for Microsoft Vista
Sep 10th, 2007 by MrGroove
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). By default it’s enabled on Vista which is OK unless your 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 good How-To write-up. Just follow the simple steps below.
Disable Windows Defender:
1. Double Click on the Windows Defender Icon in your Taskbar

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

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

4. Click Close

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.
