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
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.
