问题
I have been building a very small game in the Windows API, and in the main message loop I use GetAsyncKeyState() to test if a user is pressing the arrow buttons. I use this instead of WM_KEYDOWN because with WM_KEYDOWN there is an initial pause after the first press, and I don't want to modify a user's settings. My antivirus program flags the game as a keylogger program, is there an alternative way about this?

How is the anti-virus program supposed to guess that you are not using GetAsyncKeyState() to spy on the keyboard and log keys? You tell it of course, make an exclusion. If you're worried that your future customers are not so easily convinced then go back to using WM_KEYDOWN/UP. Use an array of 256 bools to keep track of the key state. Set it to true on DOWN, regardless of how many you get, false on UP. Also check if the scanner is happy when you stop calling the API function when your app loses focus. Pay attention to WM_ACTIVATEAPP.
