We have determined that this is due to a false positive and not due to the presence of an infectious virus. (This is due to the results of VirusTotal and the similar detection in the newly generated exe.)
And now, the latest Windows security definition files(1.371.550.0) do not detect malware.
From ver.1.2.6 or earlier, VirusTotal results seem to give false positive results to a small number of minor anti virus software.
If false positives occur frequently, I think it is necessary to change the specifications as a countermeasure(*), but I think that it will be a change that reduces the convenience of the user, so I would like to see the situation for a while.
* One file of exe, online help function, detection of user document folder location and file generation, etc. may be suspected factors.
