Windows Security Center reports Bitdefender Antivirus or Firewall is turned off

Windows Security Center monitors the security and integrity status of your PC and notifies you if any actions are needed to remedy cybersecurity issues, device performance issues, or other vulnerabilities. Most of the time, when the Windows Security Center reports Bitdefender Antivirus and/or Bitdefender Firewall are turned off, it is likely just a display issue. In other words, although Bitdefender is working correctly and is protecting your PC, Action Center shows the opposite because Windows fails to check your computer’s real status. There are a few measures you should take to check if the notifications are genuine and to stop Windows from reporting that Bitdefender security features are disabled:

  • Use Windows Action Center to activate the Bitdefender modules indicated as being off.
  • Make sure the Antivirus and the Firewall modules are turned on in the Bitdefender interface.
  • Reset the Windows Security Center check list to ensure it is not a malfunction that causes false alarms.

If your Windows Security Center reports Bitdefender Antivirus or Firewall is turned off, follow the steps below to fix the problem.

 

Step 1 – Turn on Bitdefender Antivirus from Windows Security Center

Use Windows to enable the Bitdefender modules indicated as being off by clicking on the Turn on button.

If there is only one option, you can click on Turn on and then choose “Yes” in the User Account Control dialogue, to confirm that you trust this publisher and you want to run the Bitdefender program.

Step 2 – Toggle Bitdefender Shield / Firewall to the on position

Next, check whether or not the Antivirus or the Firewall (the module that Windows Security Center reports being off) is indeed disabled in the Bitdefender interface.

1. Launch your Bitdefender security program from the Bitdefender desktop shortcut.

2. On the left-hand side of the main interface, choose the “Protection” section.

3. Then click on “Open” under the “Antivirus” panel.
