April 12th, 2017 by Admin Leave a reply »

“This app is turned off by group policy.” This is the message I am getting when I am trying to access Windows Defender. How can I sort out this issue?

When your computer infected by any malware or virus, this may cause Windows Defender to be turned off. It’s also possible that Windows Defender gets automatically disabled after installing anti-virus software. In such situation, you’ll get the following error message when you open Windows Defender:

“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”
