For those of you who use other security solutions with similar or better functionality, it might be useful to know how this program can be turned off. In this article I will teach you how to turn Windows Defender on or off, depending of your needs.

Start Windows Defender and click on the Tools button.
Under the Settings section you will find the Options link. Click on it!
In this area you will find a lot of configuration options. Scroll down to the end of the list and click on Administrator. Deselect the 'Use this program' check-box and press the Save button.
NOTE: You will might receive an UAC (User Account Control) prompt. Click on Yes to continue.
Now you will receive a notification saying that 'This program is turned off'. Click Close.
How to Turn On Windows Defender

Windows 7 will notify you that the application it's turned off. Click on the 'click here to turn it on' link and Windows Defender will be enabled again.
