Well, by an unhappy coincidence, we tend to use the terms more or less
the other way around, around here.  We call the thing that a virus
checks for the "self-identification", and we call the things that our
scanner scans for "signatures".  (The self-identification, by the way,
isn't always a string of bytes; it can be a bit-pattern in the
timestamp, or just about anything else!)  Note sure what to suggest to
solve the problem; perhaps people can just stop to spell out what they
mean when there's danger of ambiguity?
