Can I safely rely on Bitdefender and disable Windows Memory Integrity
I am using Bitdefender Premium Security, and I want to ask a direct question regarding system optimization versus security. I am considering disabling "Memory Integrity" (Core Isolation) in Windows to improve my PC's performance and reduce CPU overhead. My question is simple:Can I fully rely on Bitdefender’s layers of…
Bitdefender Mobile and the call block feature
So it would appear that the call block feature is somehow blocking facetime calls from messenger. Calls would just not show up for me top answer and if I try calling, the app just beeps and never rings. That is, until I turned off the call block feature and calls instantly went through. Is there anything that can be done…
Is this warning a scam, as I suspect? Bitdefender says my system is clear of threats.
Bitdefender VPN ads and tracker block history list
Hi everyone, I would like to be able to see exactly what was blocked by the ads/tracker blocker. Right now it only shows how many things where blocked but not what was blocked.
Option to disable Anti-Theft
It is good to have some kind of control when someone steals or you lose your device but in my opinion it shouldnt be forced and not possible to disable. Not everyone wants there to be an option to wipe their device with 1 click or track/lock it. For me personally i just dont feel safe knowing that if anyone with malicious…
Linux Support (at least VPN)
I understand market research needs to be done, but I already pay for your bundled services and have VPN for other systems. It’s silly for me to have to pay for another VPN provider because Bitdefender doesn’t support Linux, AND we can’t just download .ovpn files and configure OpenVPN. It’s 2026. Can we please figure this…
Can't Format SD Card after Immunization
Man, this is frustrating….. I stupidly let Bitdefender immunize an SD card and now, I can't delete anything from, change drive letter or even format it. It is now useless as I can find no way to remove the 'write protected' status from it. Tried a suggestion on here to change the drive letter and use Guiformat, but I can't…
Bitdefender destroyed my SD card's data
I was simply trying to edit my pokemon platinum save data, and i recently installed bitdefender. Bitdefender kept giving me an annoying pop-up notification about immunizing a drive (i still really want a way to turn that off) and it seems I accidentally clicked immunize drive instead of ****** off and now ALL OF MY DATA IS…

Latest Update?
I updated my BitDefender and its now at version 27.0.55.308, but the latest version should be 27.0.55.313. Am I right and my BitDefender didn't update to the latest version or is 27.0.55.308 the latest version?
Bitdefender Central 2FA issue
Hi everyone, Since around the same time as the forum login issue I'm having a 2FA issue with central. Central no longer remembers the cookie for the trusted device. I select the "remember this device" and it does add the device in central to the trusted devices but keeps forgetting every time I log out and then back in. It…
Remembering Last Settings for Firewall Rules
I have quite a few IP address which are blocked by BD and I was wondering if there is a way (if not could it be considered as an option) for BD to remember the settings last used when doing any of the manual additions to settings/exceptions. In particular, creating a new rule for blocking an IP, what I do most in the…

Ability to app-lock Bitdefender and Bitdefender Central app on laptop
