traffic blocked LAN and NET

Today's update has brought back all this HTTPS nonsense.  I was in the middle of viewing EVGA's website when suddenly the secure connection failed.

Sure enough, turning off Bitdefender's protection allowed me to browse the site.  I really wish you'd stop messing this up...

I agree, how can the best free antivirus alternative on the market all of a sudden turn into unusable.

What a pity - I was hoping things would get better, as I really like(d) BitDefender Free.

If it's of any use -

BitDefender Free works fine without any problems on my Windows 7 desktop (using both FireFox and Chrome)

but did not on Windows 10 laptop (Dell XPS-13 9343) - fails on LAN - however unlike others it fails with FireFox but not Chrome.

I hope things get fixed soon - for me it all started with the Root certificate install.

Just created an account to "me too" this problem.  First clue was a streaming radio station.  Today it was the venerable hive of scum and villainy Slashdot.org that was being blocked.

Frankly I was very close to purchasing a license on this product but now am having serious second thoughts.  The software has been removed and reinstalled and I can confirm that the problem still exists for the current free version. My work machine sitting 3 feet away with a corporate version of Bitdefender on it does not have the problem.

I wouldn't be so irritated except that the free version WILL NOT ALLOW YOU TO PUT IN MANUAL EXCLUSIONS.  Not that I've found anyways.  (I'm not perfect so if I've missed something please let me know.)  What happens when it won't let me get to my internal web sessions?  I haven't checked yet but I'm betting my wife is having the same issues but doesn't know it yet.

The end-all on this is very simple.  If you have a problem with your software you either give the client a fix or give the client a workaround.

Giving the client excuses is unacceptable.  So is giving them nothing.

Oh and one more thing - free software is a hook obviously.  You expect us to buy the software.  A certain percentage won't.  But then a certain percentage will.  The rest...are undecided until someone helps them make a decision.

Want to take a guess out of your free and paid client base who helps them choose your product?  Take a guess.

I spend whole hour investigating my network infrastructure to identify that root cause is Bitdefender, here are several sites I noted that were blocked:

In addition (although likely the same as the original LAN issues) my cross network file syncs have started failing, but if I disable protection or uninstall Bitdefender, they work fine.

On further investigation I found that this particular issue is only affecting incoming connections across the LAN.

I have three machines all running a scheduled file sync to a forth machine that is used essentially as a NAS. All machines are running Bitdefender, but I only had to uninstall the one on the NAS machine for everything to start working again.

It's interesting to note that as of today Slashdot.org works for me but the internet radio streams don't work unless I disable Protection.  I can then start the stream and it'll work even if I re-enable protection.  But if I stop the stream at any time it won't start again until I disable protection.

It looks like the last of these problems - the audio streaming issue - may have been fixed with this afternoons update.  This version is working ok for me:

Hopefully the next update won't cause the problem to recur.

/index.php?/profile/212285-major-error/&do=hovercard" data-mentionid="212285" href="<___base_url___>/index.php?/profile/212285-major-error/" rel="">@Major Error : Just checked mine again - the engine''s been updated to 7.74037 and everything is still working.  In the past during all these problems, when the shield has failed to activate, a reboot would fix it.  Don't know if that will help in your situation.

Gave 7.74039 a try just to see if the streaming issue was fixed. Seemed to work fine until the prompt for installing the root certificate showed up again. Restarted Firefox and it was back to the usual "buffering" on sverigesradio.se, same problem on Edge. Opera works though. Oh, well, uninstall and reinstall Avira again, won't install BD again for good while.

In the latest version, the opportunity to add exception web sites.

Didn't notice that, guess I'll have to give it one more go.

The "exclusion" option also doesn't let you exclude files or local servers.  Very annoying.  But at least my radio streams seem to be working again.

Rampant wrote: You need to add the folder of the buffer in exceptions, you have to edit config files BitDefender.

How do we do that?

On a different note now, I have the edition 1.0.9.67 engine 7.74090 and I am trying to understand how to add a file or folder to the exclusion tab. Is it possible? Because from what I see here  it only allows me to add a URL and not a folder or file.

Any help will be appreciated. 

looks like all websites that use cloudflare ssl are being blocked by bitdefender free.

I only started experiencing this website blocking a few days ago, after I saw that apocalyptic message about closing all my browsers so the BD root certificate could be installed.  Now, for a number of websites, I have to disable Bitdefender protection just to surf without mind-boggling aggravation.

As an alternative to adding exclusions for half the URLs out there (which is still not a guarantee that you will be able to access the websites properly), would removing that BD root certificate from my PC return things to normal?

I can see the root certificate in my console (Windows 7):

Can I safely delete it without causing any problems for the rest of the Bitdefender antivirus functionality?

I deleted the Bitdefender certificate in the console, just to see what would happen...  Nothing is fixed.  Bitdefender still blocks access to half the websites I visit, including my online bank.  (Yeah, I'm sure td.com is secretly a malware site, Bitdefender, you incompetent f*ck!)  I guess the BD certificates have to be removed from each individual browser that I use, but I cna't find those certificates.

*sigh*

I guess the downside to free stuff is having to deal with this level of nonsense.

So, anyone, will uninstalling Bitdefender Free fix all these issues?  Or will those BD root certificates continue to infest my browsing until I reinstall my operating system?

Maybe I'll give Kaspersky a try.  It might secretly be an FSB data-miner, but I'm sure it would still be an improvement over Bitdefender.

I uninstalled Bitdefender and installed Avira free instead and haven't had a problem since. It lacks a web security module though.

I'm having this issue as well...

Disabling BitDefender is the only way to get to websites using invalid certificates such as, in my case self-signed certificates on my private network.

I switched over from another anti-malware solution recently and I was happy with the speed improvements BitDefender offered but this issue, lack of configuration, and lack of support has me going back. Oh well...it is free so I doubt this vendor cares.

Clearly there is a bug involved with processing these invalid certificates. I wonder if a vulnerability can be derived from this bug...

Yeah, sort of seems like BD doesn't care at all. Which is sad, cause I was considering buying their premium products. But now my mind has changed.

Has anyone noticed that the windows updates on win 7 and 10 do not work properly when the antivirus shield is on?

Maybe it is just me (on 3 machines)

I would test that, but I’m rocking a different vendor of antivirus. Lol

Yes, I had to disable shields for updates and uninstall completely for the Windows 10 Fall Creators Update. After SSL and Windows Update issues, I switched over to another AV solution.

Ignore me lol.

Sorin you saw nothing.

Hi, 

If anyone is still having this issue with Bitdefender Free, version 1.0.11.15 , please send us an email at bitsy@bitdefender.com and mention the URLs that are affected and if there are any steps to take to reproduce the issue (in case only a specific function on that website does not work, etc. ) . A screenshot with the error message (if there is one) would help as well. 

To check the build number, please follow these steps:

- Open Bitdefender Antivirus Free

- Press the menu button from the upper right corner

- Choose Protection

- The version  number will be displayed under Product Information

Thank you!

I can't edit my previous comment, so I'll add info here:  I've just uninstalled BD Free and installed Avast.  I can't believe how much less resource intensive it is.  I'm kicking myself for waiting so long.

Should you ever get your collective heads out of the sand, I may return.  But, your refusal to deal with this idiotic blocking of legitimate websites has proven that you don't really give a about your customer base.  For now, I'll stick to finally enjoying an AV that works as it should.

Hope nobody minds the bump of an old post -- I was just having this same problem, and was discouraged that nobody had found a solution to the problem.  It was even more frustrating since the current free version has basically no configuration options at all, so you can't disable SSL filtering -- it's all or nothing.

Fortunately, I seem to have fixed it for myself, and I thought I'd share what worked for me.

In Firefox's options, under Privacy & Security, the last part of that section is labeled "Certificates."  I clicked on "View Certificates," and in the Certificate Manager that comes up I went under "Authorities," clicked on the Import button at the bottom, and imported a certificate I found in the BitDefender folder in Program Files:

%programfiles%\Bitdefender Antivirus Free\web\mitm_cache\fake-ca.crt

(I also imported the other .crt file in there, but I'm not sure it made any difference.)

After that, HTTPS pages finally started loading properly.

Hope that helps somebody!

Created an account just to confirm this has resolved the issue on my end as well. Just as a side note, I ran into this a month ago and removed BitDefender. Came back noticing this post. Also made sure, during the installation, no browsers were open. On the initial install of Bitdefender all was well until it updated and I rebooted a few times.

I can confirm the only thing you need to add is the fake-ca.crt; adding the other certificate is not needed. Kudos to you!
