Additionally, "If Windows tells you that Rebound.exe might be dangerous don't be alarmed. It seems to do this with every RPG Maker extractor application." why not use a traditional ZIP extension or to the very least a RAR extension rather than an executable that extracts itself?
I do believe that this type of executables are very sketchy, I don't say that your game has a virus or anything, I don't trust single EXE files that extracts themselves and it doesn't surprise me if antiviruses catch this as a malware (Even if it's a false positive).
