Now that I'm using win10, I've also decided to try windows defender for virus protection. The problem I'm having is that I can't turn it on. The message I'm getting is that defender is being managed by the administrator and it doesn't allow me to change it. Anyone know how to fix it?

Are you using an administrator account?

 

Please post the exact message you are receiving.

Here's the message: This app is turned off by group policy. To allow this app to run, contact your security administrator to enable the program via group policy.

Please answer my question, are you using an admin. account to do this?

 

Do you have another antivirus installed on this computer.

Hi, @McDan:

 

Please stick with @dc3 -- he has you on the right track to get your issue solved. :)

 

Just two more quick questions, if @dc3 will kindly indulge me:

 

  • What version of Win10 (Home Premium, Pro, Educational or Enterprise)?
  • What version of Malwarebytes -- MBAM2 or MB3?
    • There is a BIG difference here between MBAM 2 and the new version "MB3"
      • MBAM 2 does NOT report to the Windows Action Center because it is NOT an AV
        • So it is not turning off WD -- something or someone else is
      • MB3 DOES report there, because it is being marketed as an "AV Replacement"
        • Depending on how you have MB3 configured, it may be telling Windows that it is your AV
        • In that case, having WD turned off/disabled would be normal and expected.
        • If you want to run MB3 AND WD, you will need to change some settings in MB3.
        • Doing so may or may not work well on your system, however, as many users have experienced side-by-side compatibility issues with MB3 and either MSE or WD
      • Some users are not familiar with the new behavior in MB3

<pardon my intrusion>

 

Thanks,

MM

I just restarted after a windows update. The message now is: Windows defender is turned off and is currently being managed by your system administrator.

Malwarebytes is a antimalware, not an antivirus.

 

You will need to edit the Group Policy.  There are very good instructions for doing this which can be found here.

You are correct, @dc3.

 

But this is NOT how MB3 works.

This is new and unexpected for some users:

https://www.malwarebytes.com/support/guides/mb/Settings.html#winactcenter

 

It IS being marketed as an "AV Replacement".

More info here:

https://www.bleepingcomputer.com/forums/t/636274/is-malwarebytes-enough/

And countless stickies, threads, and posts at Malwarebytes forum.

It has been VERY confusing for very many folks.

It does seem like a semantic issue/marketing issue.

Whether or not one trusts the program as sole protection is another story, names aside. :wink:

 

Having said ALL of that, it seems the discussion for this OP is moot, as the version on his computer is 2.2.1.1043.

 

So, I will bow out.

I am very sorry for any confusion I may have caused. :(

 

@McDan -- please stick with @dc3.  He will get you fixed up.

 

Cheers,

MM

Well I've tried all the suggestions listed and none of them work for me. The first one gpedit results in this message; Windwos cannot find "gpedit.msc". Make sure you typed the name correctly, and then try again. Done and done. Same result. wscui.cpl brings up the defender box but the button is grayed out, so that doesn't work. Then I tried editing the registry as shown but I'm denied permission with the following message: Unable to save permission changes on windows defender. Access is denied.

Now that I think about it, this is also a problem with win 8.1 admin accounts. Unless it's setup with a local admin account (which MS does not recommend), then admins do not have full control of the os. I don't know if MS is doing this purposely or they don't know (unlikely) about it.

<I hope I am not intruding again.>

 

Win10 Home does not have GP edit.

It is only Pro and above (that's why I asked about your Win10 version).

 

There is a way to enable WD via a reg edit.

 

BUT, before doing so, the question is:  How did it get disabled in the first place by GP?

 

Two likely/possible explanations:

 

  1. You had another, 3rd-party AV installed recently.  When you uninstalled it, it did not allow WD to turn back on by itself (commonly reported issue for Win10)?
  2. Malware (malware infection can sometimes change GPs)

Did you have another AV installed recently on this same system?

If so, what brand and version?

How did you remove it?

 

>>Might be time for a speccy report?<<

 

I hope this might be helpful, :unsure:

MM

This is an upgrade from win 8.1 and I did have webroot installed. I removed it through programs and features before the upgrade. Regedit will not allow changes. Access is denied.
