You cannot really post programs (which are binary files) as a text, as text uses only a subset of possible combinations of a byte and some other combinations do not represent any printable characters (and some combinations can actually result in more characters than bytes and vice versa), while binary files use all possible combinations of bytes, so showing them as a text would corrupt these bytes and the ones that would be shown as characters would be more or less gibberish, as DOS programs are basically machine code - numbers that are read directly by the processor, not text.

Basically the companies that make antiviruses decided to use this piece of text as a test to check if the anti-virus monitors the system appropriately and picks it up. It has no way of actually harming the computer, so it's safe to use for anyone, compared to having to use an actual virus and it's also relatively simple to use.
