The most important part of CRISPR (Cas9) is its ability to colocalize with specific, arbitrary DNA sequences. It has a second function, which exists is many many other proteins and is not special at all - to cut double-stranded DNA. And in fact, that it cuts, is not actually desirable most of the time. Some of the most interesting uses of Cas9 actually try to get rid of its ability to cut the DNA (while retaining its ability to home in on specific DNA sequences).

I'm all for metaphors, but don't be afraid to shift them around when you think of a better one. (and 'malware' is not a better one...)
