Windows Defender flags newest wstunnel.exe as trojan
Author: ImfaeCreated Jan 27, 2024Updated May 5, 2026
Hello,
I was upgrading wstunnel from the 7.9.2 version to the 9.2.2 version. For client side, I downloaded wstunnel_9.2.2_windows_amd64.tar.gz for my Windows 10 machine. Immediately after unzipping the tar.gz file, Windows Defender isolated wstunnel.exe and flagged it as Trojan:Win32/Bearfoos.A!ml with a threat level of Severe.
I have, of course, overridden the antivirus's verdict and allowed the program. But having never received this warning while using the 7.9.2 version or the earlier Haskell versions, I think I should raise the issue to your attention.
And please, for the peace of mind of this ignorant user, the newest release is not really a trojan, right?
