The best solution would be the one used by Linux: Separate Data and Software.

On Linux there is a specific flag that has to be set and is not set per default to make a file executable.

So if you run something, you know that you are running it as a program and not opening it as data.

Windows on the other hand marks everything as executable which begins with MZ and whichs filename ends in .exe or .com
