On reading this I have just run the Berthier package through the Jotti on-line virus checker that check files against multiple virus checkers (19 virus checkers in total).
Only one reported a possible problem and this was from the Clam AV scanner. It reported that there was a "PUA packer" in the Gridmap, Colours and Viewer EXEs. From the Clam AV web site it says:
PUA – Possibly Unwanted Applications
ClamAV supports the detection of so called PUAs. At the moment the following categories are available:
This is a detection for files that use some kind of runtime packer. A runtime packer can be used to reduce the size of executable files without the need for an external unpacker. While this can‘t be considered malicious in general, runtime packers are widely used with malicious files since they can prevent a already known malware from detection by an Antivirus product.
Gridmap, Colours and Viewer, but not the other EXEs in the package, were developed in a product called PROFAN. My understanding is that this product does not compile source code but interprets it. To produce a run-time exe it binds the source code and interpreter together into a run time package.
It would be my guess (and it is only a guess), that PROFAN somehow packs the code to do this and this is what is being detected here.
I think this might be a case of a false positive.
However if your virus checker says something else please let me know.
