Since it can't be disabled in Windows 10?

Can another anti-virus or anti-malware program like Malwarebytes or Kaspersky, be used simultaneously with Windows Defender?

Technically can be disable,but if you install other anti-virus they will close windows defender to avoid problem.,

Windows defender is more than enough to protect you from virus/spyware etc.
Heck, if you know what you're doing, you don't even need any anti virus software.

And yes, you can disable win defender in win 10.

How do we permanently disable Windows Defender in Windows 10?

I am more interested in what firewall/anti-virus that can run with windows defender ON OFFICIALLY instead of disable it.

That's true because Windows Defender cannot be permanently disabled.

The system will automatically enable it again after a while.

Using the group policy editor.

Run gpedit.msc
Go to Computer Configuration > Administrative Templates > Windows Components > Windows Defender
Double click on "Turn off Windows Defender"
Select "Enabled" > Apply > Ok

Win 10 pro is needed for you to edit the gpe.

Most 3rd party av will disable win defender

Been using Windows Defender from windows 8 right up till now till windows 10 w/o installing any 3rd party AV software with no issues. Its basically ms security essentials combined with defender making it built in AV software.

Stopped using third-party anti-virus somewhere after the initial upgrade to win8.1 when so-called one of the best AV "bitdefender" ultimately slowed down my pc and gave a pretty nice havoc to the performance. Once upon a time my pc was infected with virus and AVG didn't help until the virus decided to spread into system files. So far, never have any issues without a third party AV. Can't say how good, but windefender is reliable, in terms of up-to-date definitions and RT scans.

(Off-topic: Not condemning any 3rd party AV in my post but only certain ones. Some longest and most reliable 3rd party AV I've used are Avast and 360.)

so far windows defender works well .. not thinking to install other AV at the moment

I'm not using any third party av after win 7

So using Windows Defender by itself without any other AV apps is good enough to protect your system?

Yup, definitely. Others antivirus slow down your device. Be sure to turn on Windows update to download the definition file for Windows defender

Been using since Windows 7. Now on Windows 10. Never been breach by any virus / etc... Touch wood. Hopefully it stays that way.

Is good enough. Don't go watch ahem ahem too much. And be abit more click savvy. Win Def is more than ever reliable

it depends on ur web surfing style, and whr u surf ehem. If U're following the basic rules to prevent virus, windows defender is definitely enough. I currently use panda antivirus + MBAE for that extra layer of self comforting.

yes

Mine Laptop also is using windows defender only. So far so good

none of my own personal system use any kind of antivirus other than Windows Defender or Security Essentials since I build my own desktop, simply because I know those AV themselves can cause troubles just like how McAfee always wreak havoc on my work laptop's networking and Norton's notoriously bad resource hogging, holes in AVG, Avast's resource hog and so many more...

truth is, i have seen more virus in computers equipped with 3rd party antivirus...

Its good but its never enough. Its all depending on the user environment. Im happy with my Norton. Works well in windows 10.
