I am getting an invalid security certificate and have been getting it a while.. This morning for one article I found said I had malware and it needed to be removed. CertMgr > certificates > Untrusted Certificates and delete the certificate. Then uninstall and reinstall Bitdefender.. Because it wouldn't uninstall, I had to…

Hello everyone :) This is my first post ever on this forum in general so go easy on me ^-^ I only have one remark to make and one more specific question / issue for you. To get the former out of the way: The frequent and repetitive notification on my phone originating from Bitdefender Security promoting the Bitdefender VPN…

I am not the only one who is not able to switch on Ransomware Remediation. When I try it the button always switches back and stays gray. I tried it also with the administrator, but also with no success. I hope anybody can help me. Thank you Francesco

I am currently studying at a university in Hong Kong and am about to graduate and return to mainland China. I am currently using a Bitdefender personal product (Antivirus Plus) in mainland China and would like to ask: 1. Are virus definition updates stable and accessible in Mainland China? Will there be frequent connection…

Hi, Rather worryingly, BD seems to have crashed on my macbook laptop and despite signing in multiple times it keeps asking for an "activation code" without which, it seems, it wil not function. I also now see TWO icons for BD in my bar, both showing not functioning. I am always uneasy when security capabilities fail, so…

When Bitdefender Shield Is active, Google search don´t work. It is a problem on both Mac and iPhone. And both in Safari and Firefox. Started on my iPhone some time ago, is now also a problem on Mac and MacBook. What to do ?

Hello. Lately, for no apparent reason, I’ve been getting a security warning from email client I'm using (Thunderbird): "The certificate for imap.gmail.com does not come from a trusted source" This notification appears only for my Google accounts. Could Bitdefender Antivirus be causing this? Or is this a security alert…

Recently (possibly following a recent update), Bitdefender antivirus no longer prompts users to scan USB drives, as it did previously. The options in the settings are enabled to prompt a scan each time. How can I fix this? Thank you.

i ld like to request to change the game mod mechanism due to a valid reason , bitdefender should switch to the game mod automatically even the game is not in the full screen mod, cuz the pc requires the same optimization regardless of the full screen mod.

Hi Bitdefender Team, I have been using Bitdefender for a while and I really appreciate the level of protection it provides for my system. However, I noticed that the interface is currently missing Ukrainian language support. With a large and growing community of users in Ukraine, having a native localized interface would…

As far as I can tell Bitdefender is scanning my USB Time Machine drives on my Macbook Pro running Tahoe 26.4.1. If I drag the USB drive to the Exceptions what happens is it only blocks that particular day's sub-directory in the Time Machine USB drive, not the whole external drive. Time machine only created daily…

I have bitdefender total security that I can install on 5 devices. When I downloaded it on my other laptop, it is asking me activation code. I have attached a snapshot.. I bought it online.. and I don't have such code. I don't need it because I can install it on 5 devices. How to proceed?

Would someone please tell how to delete my old discussions that are from over a year ago and still in my notifications, I am sure there is a simple way to do this but I am at a loss to find the answer. Thank you

when i check the the box '' disable the password for the current session '' nothing needs password again even the app is closed. it is not a normal password behavior , closing the app should lock the bitdefender's critical settings again because the session ends with closing the app. plz guide about the fix.

Within this section the interface remains unresponsive and fails to provide a save option when attempting to add a folder to the exemption list. The software should explicitly indicate that enclosing the directory path in quotation marks at the beginning and end is required for the folder to be successfully added.

Do i need to add an application here or it ll work auto? Bitdefender's Game Mode automatically activates when a game is launched, so the purpose of the Application List remains unclear. Furthermore, I'm unable to add the Windows 10 Store version of CapCut to this list, as it's not discoverable in the search. What is the…

The "Run minimized" feature is malfunctioning within the manually selected "Game Mode" profile. Specifically, when executing a game in full-screen mode, the system crashes and the quick scan interface forces itself into the foreground, completely overriding the active "run minimized" configuration. Can a scheduled…

I have been unable to have passwords in Windows using Chrome get sync'd to my iPhone. I have to enter them on both devices or change passwords for websites when I update the password on both. This is getting really old. This has been an issue since iOS 26.0 came out. Any suggestions? Other password managers have a Sync…

Hi All, While certain BD capabilities are only able to be used on the major browsers and email service providers, I AM able to utilise BD "traffic light" and "anti-tracking" on Brave browser. I also use DuckDuckGo browser, however, but (probably displaying laughable ignorance) do not see how to add those extensions to DDG…

Yesterday I received an update for my VPN I received Version 27.3.3.6 (I see that version 27.3.3.5 was released Apr. 27/26) so wondering why the version I received is different. I previously had version 27.2.6.2(b). I have Premium VPN that is included in Bitdefender Premium Security. Since the update I have seen to popup…

I would like to upgrade to Premium Security to get unlimited VPN, but I still have 9 months left on my Total Security subscription. Do I have that option?

Hello, I would like to report a reproducible FilterManager event related to the Bitdefender Virtual Disk on my Windows 11 system. After installing Bitdefender Total Security, I consistently observe the following Windows system event: Event ID: 3 Source: Microsoft-Windows-FilterManager Device: \Device\Harddisk4\DR4 Final…

When will Bitdefender VPN support dual-stack tunnels? It's pretty disappointing to be in 2025 and not have IPv6 support built into your VPN product. You even have a blog article advocating support from 2023: Why You Need a VPN with IPv6 Support

Hi everyone, I have bitdefender VPN premium, nordvpn and expressvpn. Both nordvpn and expressvpn have a add-on for firefox that allows to auto connect to there VPN servers as soon you start firefox. Could bitdefender also add this for their VPN that would be great?

Hi everyone, I have bitdefender VPN premium and it shows an incorrect download traffic amount. It shows the traffic for the last month/week as 52GB when windows only shows 12GB of traffic that month. This PC is a fresh windows 10 install for about a week now and I know I did not have 52GB of traffic in the last week as the…

I recently created a simple batch file but Bitdefender deletes the .BAT file everytime, including even the .txt file I used to created the batch file from. I rename the folder the .BAT file sits in on my C drive, I rename the file, all makes no difference, in a short time Bitdefender empties that directory. It makes no…

Windows Defender is causing problems with some of my Ham Radio Apps. Is it safe to turn off Windows Defender? What parts of Windows Defender should I leave running? Thanks, Walter
