I am having the same problems since the update a few days ago - can not access the other computer on my home LAN, or the router without turning the protection shield off.  Also, a previously available online radio station will not play until I turn the shield off.  Same with trying to access the audio link through VLC.  The log in Bitdefender shows no events and since there's no way to manually add exceptions in the new Bitdefender Free with it's 'simplified' interface I'm SOL.  I submitted a ticket online, but the canned response I got treated it as a suggestion, not a bug (don't call us, we'll call you) so I don't know if Bitdefender is doing anything about it.  Will give it a while and if no response/solution will switch to Avast Free.

Does anyone from Bitdefender follow these forums?  It would be reassuring to get a response that acknowledged the problem and confirmed they were working on it.  An ET for the fix would also be helpful.  

I would be happy to pay for an antivirus if it met certain criteria:  Performance, flexibility, effective, and most importantly reliability.  But every free AV I've tried (including BD, AVG, Avira, and Avast) have all had serious problems within the first year of using them, usually when there's a major program upgrade.  I've ended up switching back and forth, let one run until it has a problem, then switch again hoping the other has worked out their bugs by then.   I can't bring myself to pay for a product that will fail to meet my needs and require me to troubleshoot once or more a year.  Ironically, Bitdefender just popped up a warning while I was writing this saying 'Your system is at risk'.  When I looked at Protection, the shield was turned on and there are no new events listed, so I have no idea what that was about.  Very frustrating, as is the 'simplified' interface which gives no control and no information.

Hello,

Please proceed with a reinstall of the application.

Please also ensure that all browsers are closed during the uninstall and reinstall of the application

@Sorin - thanks for the response.  Since you posted, I uninstalled Bitdefender Free and Bitdefender Agent again through Control panel (had to do them separately), rebooted, downloaded the latest installer from your website, and redownloaded/reinstalled.  As others have said, that fixed the problem - in the past the problem recurred after the first update.  This time it looks like Bitdefender has gone through one update cycle and the fix is holding.  Will keep an eye on it and post the results back - hopefully there were changes made to the program or the updates to fix the problem.   Thanks again.

Hello,

Please drop us an email on bitsy@bitdefender.com with the logs from the Bitdefender Support Tool.

https://www.bitdefender.com/consumer/support/answer/1733/

If possible also include a screenshot of the error.

/index.php?/profile/201429-sorin-g/&do=hovercard" data-mentionid="201429" href="<___base_url___>/index.php?/profile/201429-sorin-g/" rel="">@Sorin G.One more piece of information for your developers.  When the NET USE statement fails (from a batch ******) I get the following error message:

System error 121 has occurred.

The semaphore timeout period has expired.

I can verify through the event logs and firewall log that the requests are going out;  it appears again that Bitdefender is getting between the response and the requesting program.  As with the other problems, If I toggle Protection Shield off, it works.  A quick look though the other forums for paid versions shows others are having the same problems.   I found one with the same error message accessing their router from Oct 5 with no response yet - maybe they can run supporttool from their paid version and provide the info you requested? 

Thanks!

Same issue. Created this account just to tag myself for any replies to this. Will be moving on to another product if no fix in the next couple of days.

Doesn't seem to be limited to a specific browser  - In my case the problems are happening in  Chrome w/ Win 8.1. Also happens with Windows explorer locking up when trying to read from another computer via LAN, from NET USE in a batch ******, and from VLC when trying to stream audio.  Consider yourself lucky if you found a workaround on your computer. :-)  

Bitdefender, please can you acknowledge this issue and give us some idea of what you are doing to rectify the issue and how long you think it will be before the problems are resolved.

Or at the very least let us know IF you are even looking at it.

Its been nearly two weeks and so far the only response has been the obligatory "do a reinstall" but clearly this doesn't work.

Just tested - I'm now able to access the router with protection on.  However, I still can';t  access the audio stream, and now turning Bitdefender shield off does not help.  I verified the audio stream is accessible from a computer that's not running Bitdefender.    When I try turning Bitdeefender back on, I get an error message from it: "Failed to activate protection.  Please retry.". If I close and reopen the settings window,, the toggle is set to 'On', but the BD icon in system tray shows it as off.

Will try uninstalling and reinstalling again today - if that doesn't work it's time to move on.

Thanks for heads up on update.

I had already uninstalled the offending version of BitDefender Free and replaced it with Avast!

Just to recap problems were on Windows 10 laptop (Dell XPS-13 9343), LAN access and Firefox 56.0.2 (64-bit), did not have problems with Chrome 61.0.3163.100 (64-bit) - I also have BitDefender Free on Windows 7 Desktop and that did not show any symptoms.

Went to - https://www.bitdefender.com/solutions/free.html

Refreshed page several times before download.

Uninstalled Avast!

Installed BitDefender Free and found the version was 1.0.8.33!

Could not figure how to force an update (of either the software or virus definition)

However things seem to be behaving well.  After about 30 minutes BitDefender automatically updated to 1.0.9.52 but apparently still without any virus definition update.

My Windows 10 laptop still appeared to be behaving well - still got access to sites that had failed previously and access to desktop via LAN.

Virus definition was just updated (about another 10 minutes later) - and things still look good.

So perhaps the problems are now over - hopefully....

Thanks

I checked on a number of sites I previously had issues with and it seems to working fine now.

That said, this morning I was on a site and for a moment I got the "ERR_EMPTY_RESPONSE" page but after a second or two it auto refreshed and showed the page. Not sure if this is the same as the TLS handshake mentioned above by FreeGuy, but after that hiccup it worked fine.

I am still having a problem with bitdefender antivirus free edition. Although the "ERR_EMPTY_RESPONSE" has disappeared after my last unistall/reinstall routine the issue of not playing sound streams persists and it happens only on radio streams not on youtube.

I have  the 1.09.52 version with the Nov 2, 07:04 update on a windows 7 system. Any suggestions from anyone? 

The problem is still here (can't access wifi router, can't access lan webcam, and so on...):

Please find a solution fast because a lot of people are getting frustrated and this whole thing is becoming a joke.

I can't confirm "all earlier issues" but I can at least watch videos previously busted.

As of 11/6/2017, early morning,  version 1.09.52 the situation is as before - no radio streaming for me

Downloaded the latest version today to give Bitdefender a new chance. Everything was fine and dandy until I was prompted to close all browsers to install BD root certificate. I closed Firefox and let BD do it's thing. Started FF and now unable to listen to radio streams again, just hangs on "buffering". Edge and Opera works though. Firefox version is 57.0b14.

Opera and the integrated VPN doesnt work while bitdefender protection is on. Used to work fine few weeks ago.

I have also noticed this.

Judging from the frequency of the the posts on the forum I can say that either the problem has been fixed for most of the users or they have found comfort elsewhere

I'm in the "found comfort elsewhere" group. Still impossible to stream radio in Firefox. Avira is far from an ideal solution but at least it doesn't mess up my browsing experience.

Version 1.09.52 and virus definition updates seemed to have corrected the problems with inaccessible websites

Same for me except for the radio streaming, LAN and router admin page is now accessible. I can also access my banking site.

Turning BitDefender Free protection Off did not seem to mitigate the problem.

This is also true for the streaming problem, Bitdefender needs to be uninstalled to make it work.

@FreeGuy - just looked, my last update also shows November 31.   Bitdefender must be in a VERY different time zone.  While it was humorous at first glance, it may portend future problems with BDs internal logs.  Sigh.

If anyone from BD Support is following this thread, would you please pass that information on to your developers?  Thanks.

Yes, I am confirming this also. And a question of different nature: If the bitdefender antivirus free is installed on a pc is the bitdefender anti-ransom tool needed?

For those who have been following this thread, I received an email from Bitdefender this morning for my ticket.  I've followed their instructions and it appears all the problems (including the one with streaming audio) have finally been fixed.  Here's the email with instructions:

Please accept our apologies for the delayed response.

 In order to address the encountered situation, please uninstall the Bitdefender product from your device, then reinstall it by using the kit below:

 https://www.bitdefender.com/solutions/free.html

 Note: Please close all your browsers (and email clients) during the installation process. Once the installation completes, allow the product to update and restart your device.

 Please let us know if everything is OK afterwards.

 Have a nice day!

One last update.  After the second automatic update since the reinstall, the problem with the audio stream is occurring again - switch the shield off and the audio immediately starts.  I'm done and will be going elsewhere for an anti-virus.

Too bad, I had my hopes up reading your previous post. For me the problems arise when Bitdefender after a while decides it has to install a root certificate in Firefox. Before this all is good. Oh well, guess I'll be staying with Avira for the time being.

 Thanks for the update. I got the same email a few weeks ago. Though most of the fix happened with 1.0.9.52, it appears they still have work to do to fix audio streams.

Actuall AZ Mountain Geek did not write that, my cut and paste is awful.
