Download normal version of Minebot Arena
This version may be claimed as a virus (it isn't) but has a functioning minimize, maximize, and close button up in the top right corner while in windowed mode (yes, that is the code virus scanners complain about).
Download anti-anti-virus version of Minebot Arena
This special version is exactly the same but does not have the minimize, maximize, and close buttons up in the corner in Windowed mode. You'll need to change to full screen mode using the options menu or Alt+Return, and close the game by Alt+F4 or the menu option. However it shouldn't get complaints from virus scanners like the normal version might.
