Like with most obscure independent titles on this site you're likely to find that virus scanners will provide a warning simply because the game is not a known executable to most antivirus suites.
I know it's a little frustrating to deal with it every time you launch things, but it's probably better to know your virus protection is paranoid rather than dangerously relaxed.
Please feel free to scan and submit the game through whichever antivirus software suite you use to get it approved as safe; the only system access this game uses is one for a disk write, which is hardcoded to read and write from the text file lintdata.ini in the same folder as the game itself (or create the file if it does not exist), simply for saving and loading your game.
