Bitdefender Free blocks most https connections on my PC

I am having the same issue, and its getting worse. As more and more sites go over the HTTPS, Bitdefender is throwing up more and more warnings about the security. But when I click on the certificate information, it is Bitdefender own certificate causing the issue. If I disable protection and refresh the page, everything works fine because the certificate now matched the site.

Please fix this once and for all, it has been going on for months now and enough is enough as it will only get worse.

Its better to tell in what browser you have a problem , FF or Chrome ?

so they can fix it

Good point...

I'm having this issue in Chrome, and I personally know several other people having the same issue with Chrome as well, so the issue is not specific to my installation.

I just recently started having this issue on both FireFox and Chrome.

I've had this problem very often in the past, and then sometimes it starts working again.

Currently it's completely broken for https://foodwishes.blogspot.com in both Firefox and Chrome. The page works if I turn off BitDefender (with Firefox and Chrome both telling me that I have a flawless https connection and the certificate is fine), but if I turn BitDefender on, I get NET::ERR_CERT_COMMON_NAME_INVALID and can't access the page at all.

The recurring HTTPS certificate troubles are extremely annoying, especially considering that BitDefender is fantastic otherwise. I just wish you could turn off that part permanently. Sadly not even upgrading to the paid version of BitDefender fixes this - in the paid version, HTTPS scanning is just as bad as in the free version, and while it can be turned off there, BitDefender then continuously complains that your system is "at risk".

If I could pay money for a BitDefender Free without HTTPS scanning, I would.

Thats a little sad, but many free AV don't have support..... but when you send a mail to Bitdefender with feedback and problems they answer very nice about the free edition.

By the way, is the problem not solved with latest update ???

I just got answer from Support of Bitdefender, they told me, they cant help me and dont care because they dont give any support "anymore" for the free version. Is this a joke?

but i could help you.

OK i really cant help you, reset your router, try to visit those pages again. Do not optimize your router settings! Which router you owe? Chinese or what.

For what it's worth, for now everything is working again for me!

(Until the next time it breaks, I guess. But BitDefender Free is still the best antivirus I ever had, so I'll take that.)

Maybe it depends how you uninstall it .....using that uninstall tool or with another program.

 I disable protection and refresh the page, everything works fine because the certificate now matched the site.

Why you say the same 6 hours later ?

UPDATE:

I did what your suggested and it made things worse. First off, the path for the cert is wrong but I found it in a similarly named sub folder. But now, instead of getting the "web page is blocked" error which normally goes away after refreshing the page, now I get the "your connection is not private" error (see attached image) just trying to do a google search, let alone any other sites. Now its just an effing mess and I guess I have to delete the certs again and do a clean install of Bitdefender.

PLEASE FIX THIS PROBLEM OR REMOVE WEB PROTECTION UNTIL YOU CAN FIND AN ALTERNATIVE SOLUTION !!!

.... and I'm still getting this one as well.



Haven't seen it for a few days so I thought maybe and update had fixed it, but alas not. I guess I was just "lucky". But at least with this one, refreshing the web page normally fixes it.

PLEASE FIX THESE ISSUES!!!

Its now another 2 months later and well over a year since this issue first started, and still there is no fix!

Hoping beyond hope that by some slim chance, a clean install of a new version, might fix the issue, I once again uninstalled Bitdefender for the umpteenth time. I manually removed any trace I could find and manually deleted the certificate etc etc. Suffice to say there was no trace left that I could find. 

I downloaded the latest installer and...... etc.

No sooner had I finished this clean, brand new install of the latest version and went to a secure site, I immediately get the error again, on a banking site. This happens in both Firefox and Chrome, but NOT necessarily with the same sites. Sometimes I'll go to a site and it will work, other times it will give the error. Sometimes simply refreshing the site will display the site and other times I'll get the error again. With regard the later, if its a site I don't know and I get the error more than once, I generally heed the warning and move on.

This error has been going on far too long. When can we expect this to be resolved?

Hi,

Please write us an email at bitsy@bitdefender.com and our team will gladly help you.

OK, so I have just done a fresh reinstall of my laptop and I started getting this problem in Firefox. The sites I tried were Google and BitWarden and they gave me an error like the one I have attached to this post. I have tried some solutions I had found around here and elsewhere (including removing the Bitdefender cert in Windows and readding via the "Manage Computer Certificates" application), but this only served to spread the error to Edge too. In the end, this is what seems to have done the trick:

EDIT: After playing with it a bit more, I believe there may be some extra steps; I have added them below and reformatted the post.

1. Open the certificate options in Firefox (Options -> Privacy & Security -> View Certificates) and the "Manage Computer Certificates" in Windows 10 at the same time.

2. Delete "Bitdefender Personal CA.avfree000000" in the Windows app and immediately Delete/Distrust it in Firefox too.

3. In Firefox, import "c:\program files\bitdefender antivirus free\web\mitm_cache\fake-ca.crt" -> "Trust this certificate to identify websites".

I'm not sure if there are any implications to doing it this way, so I would appreciate an actual fix

Also, slightly off-topic:

- I have made this account a long time ago and I couldn't remember my display name in order to log in. I couldn't find it anywhere until I tried the password reset function and received it in that e-mail. The display name should be made visible in the Central!

- I tried sending an e-mail via the contact form, but I was getting an error; I'm not sure what the exact message was, but it seemed like I was expected to fill out a Captcha, but there was none (I actually went to check now that the problems are fixed and now a reCAPTCHA appears). You should provide an actual e-mail address so that people can contact you when a failure like this happens.

Hi.

I have tried that before and got a copy/paste reply to follow xyz steps, which I've done several times and none fixed the problem. Would it not be easier for your team, if they have a solution that works, to address it here so that everyone with this problem can be helped?



I will email them again about this issue anyway, as well as a new problem, almost certainly related in some way to the same issue. As of an hour ago right after an update, PUBG server is now being silently blocked making it impossible to play the game unless I turn off "Protection Shield" after which it works fine.



Blocking websites I can see is irritating enough, but when you start silently blocking access to servers without any indication or warning just causes heaps of frustration.

The only solution was to go to firefox's options->Privacy & Security, scroll all the way down to certificates-> view certificates-> authorities tab

If the bitdefender certificate is not on the list, then click on import, then go to location C:\Program Files\Bitdefender Antivirus Free\web\mitm_cache

Import fake-ca.crt and tick "This cerificate can identify websites".

Now, firefox works for me with bitdefender free alongside. Should be easy for developers to incorporate it in future updates.
