I think that we have to remember that our friendly viruses can often attack
and attach themselves to several different types of Macintosh files, including
System files and applications.  So if someone uses a previously uninfected
application on a Mac that has been infected with a virus, that application
could become infected itself.

Now, suppose the user takes that newly infected application and gives it to a
friend, or uploads it to a BBS.  Now the application carries the virus to
whichever Mac it is used on.  And so it spreads from Mac to Mac.

This is the way many viruses are intended to work.  They infect "innocent"
applications and use them as carriers, to further spread the virus.  Singling
out a certain program as a "Trojan Horse" just because a copy of it was
infected in this manner is completely unfair and can do unreasonable harm to
the reputation of that program.

We have to be careful to make a distinction between programs that have been
innocently infected and those that were infected on purpose by the virus
author in order to distribute the virus.  In the former case, only a few
copies of the application will be infected, and the problem will often be
related to the distribution of that originally infected copy.  In the latter
case, _every_ copy of the application will be infected, universally.

Unfortunately, this distinction is likely a very difficult one to make for the
isolated user.  That's something we can use the nets for.
