Any Macintosh virus that spreads when an infected program is executed
can be spread over AppleTalk networks, IF you are using file sharing
or file server software such as AppleShare or TOPS.  If you execute a
program on a remote computer that happens to be infected, the System
software on your local computer can be infected.  From there, you will
infect any other program you use.

nVIR is particularly effective at spreading from program to program in
this way, so be sure that any shared software, or anything on a shared
file server volume, is clean.

As evidence: my hard drive was heavily infected with nVIR when someone
else on my network (I'm running TOPS) asked to try out the software on
my drive.  He executed a couple dozen programs... shortly after having
played an nVIR-infected game on his own computer.  The disk containing
the nVIR virus was never physically even NEAR my computer.
