Mullvad Browser blocked by v25.2
Hello,
I've tried submitting the file twice and adding the information that could be helpful, but it never finishes uploading to F-Secure.
Previously Mullvad Browser would run with F-Secure versions 19. at least as far as I remember. Now it is being quarantined by F-Secure as Drop.Win64.MemMapSelf.9214
When I checked the download, which was from Mullvads site on Virus Total, it only showed on obscure vender as flagging it. F-Secure did not give me a pop up notification, but only shutting Mullvad down after it has been running for about 3 seconds. I had to look in the Quarantined section to find out what happened.
Is this a false positive? I'm on v.25.2 (6.0.1641.0)
Thank you.

Yep, here it is. It wasn't flagged when I did a right click scan, but only after installing it and running it. I did a Windows 11 restart and when it was up and running for about 3 seconds it was shut down by F-Secure as I mentioned above.
Thank you, Firmy, for getting back to me so quickly.
Kind regards :)

Hi, I too have this problem. In the last week 2 updates of Mullvad Browser are 'blocked': the file mullvadbrowser.exe is in quarantaine. Infection: Drop.Win64.MemMapSelf.214 and …222. I can't believe the file is dangerous. I uninstalled en re-installed, updated from within the app, but the result is the same: I can't use Mullvad Browser anymore.

You'll probably need to add it into Exclusions, as someone else on a different forum mentioned the same thing. It was okay for awhile, then I guess the update caused F-Secure to flag it and quarantine it again.
Or, you could do the same thing I did, and report it as a FP from here.
Kind regards.

Here’s how you can stop F-Secure from deleting Tor Browser:
Step-by-Step Fix
Option 1: Add an Exclusion (Recommended)
Open F-Secure (e.g., "F-Secure SAFE" or "Internet Security").
Go to Settings →
look for Virus Protection or DeepGuard.
Find Excluded Files and Folders or Exclusions.
Add the Tor Browser folder (e.g., C:\Users\YourName\Desktop\Tor Browser or wherever it's installed).
Optionally, add the Tor Browser executable as well (firefox.exe inside Tor folder).
I added the whole folder and the problem is gone
