Windows 10 Security Center falsely report Bitdefender is disabled


I use Bitdefender Antivirus Plus 2015 on 2 PC's (it seems not possible to post under the Bitdefender 2015 section).

Bitdefender itself works fine and initially Windows 10 Security Center recognizes it correctly: Bitdefender Antivirus enabled and Windows Defender Antivirus disabled.

However after updating Bitdefender, Windows gives false warnings that both Antivirus applications are disabled.

When I click on it, it opens the Security Center menu (screenshot). When I click on 'Open App' (1) -> nothing happens, when I click on 'enable' (2) it activates Bitdefender real-time protection correctly if it's disabled (but in this case it was already active).

I took these action with no results:

- Followed steps on https://www.bitdefender.com/consumer/support/answer/9329/

- Reinstalled Bitdefender --> problem solved until the automatic Bitdefender update is installed.

- Turned on/off autopilot, disabled and activated Bitdefender, ...

Problem is present on both PC's.


What can I do about this? It appears that the problem is introduced in a certain Bitdefender update.
