Windows Defender 10 and third party AV

[LabZero]

Windows Defender in Windows 10 can never be turned off from the program interface; Disabling real-time protection software will remain temporarily disabled and wakes up alone after 10 minutes of inactivity or after a reboot.

To disable it permanently you need to use a third party tool, or modify the registry.

My question is: using FSecure IS or other antivirus, you must disable Defender, or you can use them both simultaneously?

My question is: using FSecure IS or other antivirus, you must disable Defender, or you can use them both simultaneously?

Windows 8 and Windows 10 have built-in mechanism where it automatically shuts down Defender when it detects that AV is installed. That's also why you can't turn it on. Windows will not let you.

So when another an anti-malware program such as F-Secure IS is installed to Windows 10, it will trigger Windwos Defender to shut itself down/be disabled when F-Secure IS registers itself to Windows.


From How To Geek:
Windows 10 will automatically disable Windows Defender if you install another anti-malware program. It won’t continue performing real-time scans, so it won’t interfere with your other antivirus. Try to open the Windows Defender settings pane with another antivirus installed and you’ll find every option grayed out. Click the “Use Windows Defender” link and you’ll be informed Windows Defender has been disabled. Windows Defender will pop-up and say “This app has been turned off and isn’t monitoring your computer.”

If you uninstall the other antivirus, Windows Defender will kick into gear once again and take over, providing antivirus protection.

The fact when a third party AV recognize by Microsoft from their approval then its API that contains algorithm should turn off any possible of conflict.

Not recognizing issue, may happen when a third party program does not have the registration ability to turn on from Action Center.

You can disable WD via registry if you are so concerned:
Via registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
Look at: DisableAntiSpyware DWORD
0 = On
1 = Off

By the way, not all AVs automatically disable WD in Windows 10, most likely because none are fully 100% compatible with the OS itself.

Don't worry when you'll installed any recognised windows anti virus software defender will ne disabled itself.

Not really. WSA never disabled WD for starters.

Avira was supposed to do the same when Windows 7 came out. Only started doing it officially few months after (despite claiming it would disable).

WSA? that might not be recognized one.

Don't know about 10.But it is recognized in 8.

 

[Soulbound]

WSA is certified and recognized since windows 8.

They did however notify users in forums that it wouldnt disable WD. Been a WSA user for as long as I can remember

I am an active WRSA (Webroot Secure Anywhere) beta tester and it does deactivate WD on install I know first hand, Bitdefender had issues but it too now toggles WD properly.
As far as FSecure goes I would read this from the FSecure community and maybe upgrade to something with a better compatibility record --> https://community.f-secure.com/t5/Security-for-PC/Windows-10-installation-might/ta-p/72173

Read a bit further down to TripleHelix's post, and thats dated 2014.
The version WRSA v.90135 and above functions properly on Windows 10.
I know im new and not well known yet, but i promise if i dont know or am not sure i will not post a reply. PeAcE

I can assure you that WD did not get disabled when I installed WSA as well. no one criticized if you were new or not, so no offense to be taken.

Is Webroot aware of your issue, did you post in the support forums ? If so I can log into the Beta portion of the forums and bring your issue to the attention of the proper support staff, they are usually very friendly and quick to assist.

By default, whenever Win10 thinks you don't have an AV running, it will enable WD; when it thinks you have one running, it usually disables WD. I had to disable WD from Group Policy since it was activating on boot and not always shutting off.

It's always telling me in the notification centre on boot that I don't have AV protection.

I am not running WSA at the moment due to memory leaks. myself am a beta tester in webroot I do however run on a windows 8.1 machine and works fine. All i did was to manually disable WD in that machine.

i use webroot and just upgraded from win7 to win10. defender ran for about a day and then turned off; though, i'm hearing that the mse to defender thing isn't transitioning well on everyone's machines ... so i am unsure if wsa turned defender off or its just a bug?

i did read in webroot's forum that triplehelix did say that wsa did turn off defender in win8. so it will likely do so in win10(?).

 

[jamescv7]

@ChoiceVoice : As much as possible in any case, either WD itself turn off or WSA do it (vice versa); the importance is that an operation occur to give way for third party AV to install and recognize by Action Center.
