How to disable Windows Defender


Even if Windows Defender is offered for free and it has decent protection features, some people might prefer other applications to secure their system from spyware and other threats. In this case there is no point in having two similar applications running at the same time, both of them consuming system resources. This is why disabling Windows Defender can be a good idea.

This is how you do it:

Launch Windows Defender and go to Tools -> Options.

Windows Defender

Here you will find a lot of configuration options. Scroll down to the end of the list. You will find there a section called Administrator options. Deselect the Use Windows Defender box and press the Save button.

If UAC is turned on, you will need to confirm that you want to continue with the change.

Windows Defender

Now you will receive a notification saying that "Windows Defender is turned off". Click on Close and you are done.

Actually, it IS a good idea to have more than one program of that kind installed but not running at the same time.

Thank,
So, I'm Thai people from Thailand. My English is no good, Sorry.

Version...

Which version of Kaspersky are you using?

Kaspersky Anti Virus

Thank Ciprian,
My Kaspersky is 7.0.0.125 and update everyday.

Disable it!

Kaspersky v7 offers additional real-time protection from spyware and adware so you do not need to keep Windows Defender running at the same time. You can use it to scan your system from time to time, to have a 2nd solution make a clean-up, just in case Kaspersky missed something.

Thank!

I Disabled, Very thank.

about KAV

Kasperksy anti-virus has good capability of detection ,infact has a good fast detection but the removel and the self-defence of kaspersky is very weak and cannot provide satisfactory protection when virus like autorun executed because sometime infected self and the virus spread rapidly but the kasper internet security is very excellent .........Maximum protection from Harmful website and Ad.s ware

disabling w defender

Hello
I have Virus Scan Enterprise and AntiSpyware Enterprise 8.5.0 and after reading your article, I am assuming I can disable W defender, is that correct? thank you.

Correct

Yes, that is correct! You can disable it.

Windows Defender

On the contrary mbsamart, I think you should leave Windows Defender running, as kaspersky doesn't catch many spyware related items, especially the lower end ones like cookies and certain malware. When they said it isnt a good idea to have 2 programs, they meant 2 spyware-centric applications. Kaspersky is not one of those, so it would still be in your best interest to have some sort of antispy app running.
