Bonjour. Mon logiciel Bitdefender télécharge une mise à jour dénommée "sav/explode.dll". Je n'avavais jamais vu un tel nom auparavant. Est-ce une mise à jour légitime ou un hijacking réseau me faisant télécharger (via le programme antivirus Bitdefender lui-même, pas sur un site obscur) une dll pourrie ? Google ai m'affirme…

this doesn’t fix the problem !

Hello. My computer was running very slow. The RAM usage was 85%. I took it to Best Buy Geek Squad who said the number resource user on all tests was my antivirus, i.e., Bitdefender. Are others experiencing this? If so, what did you do about it? What do you suggest I do? I like Bitdefender but it's really slowing down my…

hi, I installed Bitdefender Total Security on my Windows 11 Laptop. Since the installation, I cannot back up the laptop onto a USB drive as the back up software is reporting the drive to be inaccessible. I cannot access the drive to read files but the back up software does not work.

(1) Following Clean install of W11 (from an MS Account to a local account ), all attempts at installing Total Security fail - all I obtain is BD Agent whose function is doubtful. (2) Contacting support means obtaining some sort of robotic (or standard) response recommending BD Central and access to "My subscriptions" .…

I have a license for Internet Security, but I want to install only the Antivirus Plus version (the one without the firewall). Is this possible, and if so, how do I do it? The installation process forces the use of the license associated with my account, and I cannot change this. I should also mention that I do not want to…

I have three Windows 11 systems with valid Ultimate Security subscriptions. All three are still on Bitdefender 27. Are the upgrades still rolling out? Thanks.

Hi, Today after an update that completely changed Bitdefender's UI (which is awful btw), the security widget that was on my desktop is gone. Also when I right-click on the Bitdefender icon in the system tray some features are gone, I can no longer see the product information with the exact dates for the last product…

VPN and security solution now integrated into Client. New Client: 2.0.184 My Bitdefender has been updated to Version 28, Client version points to 2.0.184 and the Security tab points to Version 28.

Using Bitdefender Total Security on a Windows 11 Home version, I have been prompted two or three times by Bitdefender Dashboard that I needed to update my version and each of these times it was running long on 0% with no upgrade being downloaded so I had to cancel the update. In Settings I noticed that Automatic & Silent…

Hi everyone, I'm posting to see if anyone else has encountered this issue or if the Bitdefender team can advise on a fix. Inside Bitdefender Mobile Security / Ultimate Security on Android, under the Scam Protection Pro menu, both SMS Protection and Scam Notification Protection fail to remain active. When toggling them on,…

Hello, I have two remote PCs, A and B. I remote to PC A then use NoMachine to connect to PC B. A while back I was trying to add a firewall rule to only allow a NoMachine on port 4000 from a specific IP address belonging to PC A. I added the rule, and immediately after adding it I was disconnected from the NoMachine…

The DiscoverySrv.exe version 27.1.1.45 that installed on my laptop on 14 August continuously is using 25% of my CPU and generating a lot of heat on the laptop. This was not an issue prior to this version being installed during the 14 August update. The file itself shows as created on 11 August. My laptop is running Windows…

I have purchased Bitdefender Premium Security to use on a new laptop for my wife and I. I have installed it using the admin account (which is also my MS registered account). I have sent emails to my wife and I (using a different e-mail address), which have been received. So far so good! Now when we accept the invite, we…

Forgive me if I do not use the correct terms as I am Dutch. When I try and open the installation file of Total Security as an administrator, nothing happens, except there is a message on my screen: flow.bitdefender.net is trying to save something Can someone please help

At present Firewall is showing that files are modified and wants to connect when the file is not ( at least on disk, checked with hashes ). Either an update was pushed that introduced an issue or I have a very stealthy in memory rootkit that is changing all sort of things on the fly and not stepping on disk and Bitdefender…

Hello, I'm currently running Bitdefender Total Security on two different Windows 11 PC. One of the machines is quite old, the other one is much more recent. I updated Bitdefender on the two PC manually (using right click on the icon > update). After updating both machines, I can see the threat database version number is…

I ran a full scan that supposedly removed a trojan on my computer. Upon the scan finishing I could see the log. I went back in to see the log but that actually started a new scan which I terminated. The only scan I see now is for the terminated full scan. Is there no way to see a scan prior to the last one? I looking under…

The initial uninstallation of Bitdefender completed with errors. To address this, I first ran the official Bitdefender Uninstall Tool, and immediately after that, I…

so, a new user here, coming from norton, where I was under the impression that norton has a lot of bloatware and it's slow. I just installed BT Total Security and after a scan it seems there's a tremendous amount of active processes and one of them taking some 800mb, even idle (probably the scanning one). Should I be…

I want to reinstall Windows to a different version, and I'm wondering if my Bitdefender antivirus will continue to work or if it will require me to re-register the device as a new one?

The most recent update has broken something serious.C:\Users\username>start vivaldi --enable-logging --v=1 --disable-gpu C:\Users\username>[43012:35100:0531/191328.960:ERROR:chromium\content\browser\gpu\gpu_process_host.cc:1000] GPU process exited unexpectedly: exit_code=-1073741790…

The update scares me every time. A 'missing in the path' install is making connections from a RAR Temp folder. It is in Windows Temp, but there should be a better and secure way of doing things. I'm not even sure how the files are checked, with cert pinning or hashes or what, but my guess would be that it won't be…
