I'm using "Bitdefender Antivirus Free Edition" on my Windows 10 home PC Antimalware Engine 7.73769

During the last days I got a popup which asked me to shutdown Firefox/Thunderbird/Chrome in order to install "Bitdefender Root Certificate"

This sounds much like a mand-in-the-middle approach to analyze my SSL web traffic: a feature I never asked and which I never accepted to install. I've opened the antivirus console and there's no option to disable this feature.

Above all I don't see this root certificate in the Firefox (56.0.2 x64) authorities.

I would like to:

  • 1) disable at all the web traffic inspector
  • 2) uninstall the root certificate from all the browsers

so question is:

  • How to disable web scanning in this antivirus which has a minimal GUI
  • how to find and remove this certificate from Firefox (and other systems): I already looked at the secriuty settings and there's nothing like "Bitdefender Root Certificate" authority

How to get rid of Bitdefender Free edition certificate mess in Firefox (Windows 10, Firefox 57.0.2, Bitdefender FREE antivirus)

1- Check if https://unsplash.com is hijacked and certified by BitDefender

2- Uninstall BitDefender Antivirus Free

3- Uninstall BitDefender Agent

3- Reboot Computer

4- Start Firefox Check https://unsplash.com -- Should be certified by GlobalSign now

5- Reinstall Bitdefender Antivirus Free - Do NOT close Firefox when asked, just cancel BitDefender Root certificate installation

6- Let Bitdefender finish its installation.

7- Reload unsplash.com, another popup should appear, and cancel again the Bitdefender certificate installation.

8- From now, your Firefox should be immune to BitDefender certificate (close and restart then reload unsplash.com to be sure).

9- For extra Windows cleanup, remove the Bitdefender certifcate using certificate manager.

10- You can check residual rogue certificates in windows with sigcheck from SysInternals ( 'sigcheck -tv' in a console)

No side effects noticed yet.

    This works for Firefox. Has anyone found a solution for Chrome (i.e. disable the SSL sniffing without disabling Bitdefender entirely)? Deleting the root certificate just breaks SSL sites completely. Jan 7, 2018 at 21:37

    Why is this a "mess", why not just allow Bitdefender to do its thing?

    How exactly do you do step 1? And what do you do differently if the answer is Yes vs. No.

    I figure you already found it, @Mick but you just check the certificate of the page, though that domain is not a valid test for me, it's never overtaken by bitdefender.. VISA home is getting intercepted though O.o Aug 25, 2018 at 12:36
