unfortunately theres nothing wrong with the files... its just antiviruses that are annoying these days, and detect everything that is not popular but at some point in the past were used to create malware as suspicious trough heuristics, so its probabily possible to have the exe "packed/protected" to hide the signature from the antivirus detector, i will do some research on which one works best for that (altough the proper way to fix that would be for everyone to report to the AV company as safe, so they fix this discrimination they have)
