Under one possible interpretation of that, it's a result of Rice's theorem. A program is malicious if it performs some malicious action, which makes it a semantic property. Some programs are malicious and some aren't, which makes it a non-trivial property. Thus, by Rice's theorem, it's undecidable in the general case whether a program is malicious.

I'm not a mathematician, but I might guess that Godel's incompleteness theorems might also apply.
