The program itself certainly isn't a virus, I have the latest norton and latest updates, I test all my programs to make sure they are safe before I distribute them, norton maybe isn't picking it up because it is not a trojan.
I have been Reading up on why it may be suggesting it is a virus, it could be what aagreen is suggesting about the installer which it seems to be suggesting because of its compacting method or, a problem other programmers who use autoit have had problems with false positives is because autoit compresses EXEs using UPX compression which apparently some virus makers use to make the virus files smaller and it could be comparing this with infected files using similar compression, these are the only things I can think of that is causing it to be suggesting it is infected. This is annoying, I was just trying to make a program to aid the often difficult task of updating your game.
