The veto message you got probably had nothing to do with the nVIR B
infection.  (However, if you'd tried to run Drawover before disinfecting
it, you probably would have gotten a message about nVIR B.)

Yup.  ADoBe Separator uses ADBS for it's creator signature.  Sadly, the Mac
OS also uses a resource called ADBS for the Apple Desktop BuS.  The latter
is executable code, while the signature resource isn't.  GateKeeper blocks
unprivileged attempts to add executable resources to file, and is obviously
mistaking the totally harmless signature resource for a nasty virus.
Stupid GateKeeper :-)  The solution here is to simply not use applications
that use resource names as their application signatures.  Stupid Adobe :-)

] Why would opening a folder require adding a resource to the desktop
] file?

The Finder keeps track of which icons to display for which files.  To do
that it stores the icons, signature resources, etc. in the DeskTop file.
If the Finder discovers an unknown file in a folder, it will attempt to
add that file's identifying info to the DeskTop.

] And why did Gatekeeper veto it on one disk, but not the other?

I dunno.  The Finder is often mysterious to the semi-initiated (like me).
Perhaps an expert can take the rest of the questions?
