Right, I understand your point. But the internet is full of threads discussing darktable to be recognized as malware. Also here.. There are also workarounds suggested, to get darktable downloaded or installed. As far as I know, it was never proven, that darktable did anything wrong. So, one could say it’s always false positive and the fault of the malware detection programs. However, you can never exclude, that somebody actually manipulated the binary.
In the end it’s your decision, whether you want to look for a workaround. Of cause, you can also open a bug report for darktable but my guess is that the developers can’t help.
