Package: x2goclient, windows

Version: 4.1.2.2, maybe others

Firefox flags x2goclient-4.1.2.2-2020.02.13-setup.exe as a virus. No further information is provided.

I found links to a folder with earlier versions from this page:

x2goclient-4.1.2.0-2018.06.22-setup.exe was not flagged, indicating that the issue is in more recent builds.

Workaround: Downloaded and installing the older version from here: https://code.x2go.org/releases/binary-win32/x2goclient/releases/4.1.2.0-2018.06.22/
