Norton Anti-Virus detects tor-0.3.5.8-win32-brave-1 as a trojan horse

Description of the issue:
Norton Security Antivirus will flag the latest tor executable in Brave 1.4.95 as a trojan horse virus. It will delete it too. However, tor still works inside brave.
How can this issue be reproduced?

  1. Update to the latest version of Brave
  2. Have Norton Security AV
  3. Norton will delete the file telling the user it was removed because it contained a Trojan Horse.

Expected result:
The executable should not be flagged as a virus (unless it is?)

Brave Version( check About Brave):
1.4.95

I can confirm the above problem. Just had exactly the same report today ( March 4th 2020) from my Norton Internet Security. version 22.20.1.69. That is: tor-0.3.5.8-win32-brave-1 flagged as Trojan and removed.

Symantec Endpoint Protection also detected this problem. Any concerns with this.

Same here

I had a user report this to my office yesterday. I told the guy it was just a false positive, but left it as it is for now incase I need to restore the file from quarantine.

Dell Latitude 5280, W10 x64. SEP v14.2

Likewise, Symantec on my work laptop is flagging this file and I can’t open Brave, which more importantly means I can’t get my bookmarks, really causing issues because I depend on a lot of those links.

Hello all,
It’s likely false positive. In the past we received a similar reports from other AV. If you can, you can “whitelist” it for now.

Same here but with Windows Defender. It identified Brave as Trojan: Win32/Skeeyah!MTB

Currently seeing this with Windows Defender as well: Win32/Skeeyah!MTB

It’s being flagged as a PUA, potentially unwanted application, for the most part and anything else is a false positive and probably needs a signature update for the checker:
