False positive, antyviruses and other programs flag unknown programs like that left and right.
Doesn’t mean anything - the antyvirus just doesn’t have it in its database.
You can compile yourself a “Hello World” program and your AV will probably flag it as well 
If you want you can download the code from GitHub (.exe will get deleted I guess), check out the .ahk files that there’s nothing there besides pressing buttons
and compile it with AutoHotkey (nothing complicated, just a few clicks and need to select GDAutocaster.ahk and click Convert)
Compiling is not even needed because AutoHotkey can just run GDAutocaster.ahk script
but then you need to have AutoHotkey installed permanently on your machine.
Really not my fault 
I personally consider Antyviruses to be malware the way the slow down your computer / affect your files.
