OK but how they can infect MOS?
Um, execute the infected binary?
I wasn`t speaking of MOS 68k compatibility, but of need for the library.
Well not many other packages allow scanning for amiga viruses on other platforms so I can see use for it.
Surely, you could copy library and run VirusZ on OS4 also.
Assuming the library and VirusZ works under OS4. xvs.library has some extreme measures to verify the integrity of the library itself. It isn't taken that it works under OS4. Maybe it does.
What I know is that xvs.library does work under MorphOS, along with VirusZ.
