Hi! I downloaded hortonmachine_0.10.2 zip file available in releases, and at the moment of extract my antivirus detected a trojan in two executable files: geopaparazzi_viewer.exe and wms2geotiff.exe . I submitted the files to a specialized portal and other antivirus engines also detected trojans in same files. I have the screenshots if you want to know more about it.
Now, the 0.10.4 zip file also has detected with the same trojans.
