Hi All,
I tried to update the Windows Defender virus definition but I can't access the Windows Security Center.
This App has been blocked by your System Administrator.
Any idea how to solve this issue?
Thanks,
Yared.

Is your PC part of domain or company's network?
Have you installed any third-party Anti-Malware product?
Since when this problem started?
Hi,
Yes, it is part of the network
we had MacAfee before but we no longer use that.
I don't when the problem started because we never use it until now.
do you think this is because some setting has changed in the group policy?
Thanks,
