Hi Russel,
this is false positive. And I, as an author, can confirm that there is no trojan, malware or whatever inside :)
Here is a virustotal check which shows that only 1 of 52 antiviruses found something for installer file (this also false positive). Of course, I am trying to contact antivirus vendors for adjusting their checks, but it does not always work and usually takes some time to be processed.
Best regards,
Alex.
