Mullvad Browser blocked by v25.2

TVC15

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

https://www.f-secure.com/en/support/search#q=Drop.Win64.MemMapSelf.9214&f:@source=%5BThreatDescriptions%5D

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.

Hello @TVC15

Thank you for your question.

Could you please let us know which version of Mullvad Browser is being blocked by the F-Secure app? We will investigate the issue and coordinate with our labs to verify the detection.

Looking forward to your response. Wishing you a wonderful day.

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 :)
