The "RBF34 TROJAN" - what it is, how to deal with it.
There are two modules included which are: 
"FixFD"  scans the structure of an entire drive & tests/repairs all 48 file
descriptor segments of each file, not just the 48th).
"FixTROJAN" deals with the root of the problem - the RBF module itself.
It was designed to diagnose & disable the "RBF TROJAN" in both OS9Boot
files & standalone RBF modules (it doesn't touch the copy in memory,
though).
