Windows Defender: Can you run alongside another anti-virus?

    In Windows Defender on Windows 7/8/8.1, I used to be able to go into the program's administrator settings and turn off the program. I would then install my anti-virus of choice, which is usually the latest Kaspersky Internet Security client.

    However, it appears as though you cannot fully disable Windows Defender. It will eventually turn itself back on...what a great feature! (sarcasm).

    So, when I check my security settings in Control Panel, I will see both Kaspersky and Windows Defender active, with that special warning telling me that running two anti-virus programs simultaneously could cause issues. I understand this, which is why I want to disable the piece of garbage Windows Defender.

    So, my question Windows Defender designed to run alongside 3rd party anti-viruses now? Is that why they don't give you a way to fully disable it?...because it's not necessary? Or, is this some push to get me to use crappy security software that will do minimal to protect my PC?

    Now, I did find the registry key to disable Windows Defender permanently. So, I did do that.

    But, you'd have to think that the average consumer isn't going to be editing the registry. Did Microsoft not expect users to install other anti-virus software? Something doesn't seem right here.

    Let me know if I'm missing something.

    Thanks for the help!

    try gpedit.msc then go to "computer configuration", "administrative templates", then "windows components"
    choose "windows defender" on the left, double click "turn off windows defender" on the right and choose enable then click ok

    doing that here shows up as disabled

    Thank you for the reply. I did disable Windows Defender via Registry Key already. So, there's no problem disabling it by editing the registry. My question is, why do I have to do that? If running two anti-viruses at the same time is counter-productive, why would Microsoft make it so that you can't fully disable Windows Defender via options? Not everyone wants to use that program. So, if you purchase a third party anti-virus, you'll be using two anti-viruses essentially. Windows Defender, and 3rd party program.

    The average person isn't going to go into the registry to disable Windows Defender.

    Windows Defender is supposed to be disabled by any third party AV-software.

    Running two antivirus at the same time is a bad idea. If one of the two is defender the idea is ugly.
