    If you have installed Antivirus softwares, it might disable Windows Defender because it might interferes with other Antivirus solution program.

    If you have one of the following AV, anti-virus, programs installed, it will shut down your Windows Defender. Reason being those AVs have their own defenders. 2 defenders running in the same machine will create conflicts.
    Bottom line : it's ok. It's normal.
    List of AVs that will shut down Windows Defender :

    Norton
    McAfee
    AVG
    Microsoft Security Essentials

    If you do not have the above AV programs, here is how to restart Windows Defender:

    Start button > in the search box, type Services > press Enter key > scroll to find Windows Defender, click it > ....
    under Status heading, it should say ......... Started
    under Startup Type, it should say ............ Automatic
    If it does not say that, Right click at Windows Defender > click Properties >
    at Startup Type, click the pointer at far right and select Automatic
    at Service Status, click Start
    click OK when done.

    If it solves your problem, I did it. If it does not, my twin brother did it.
