[comp.virus] Is this a Macintosh Virus?

DQB@ORNLSTC.BITNET (07/19/89)

Has anyone ever encountered a virus that changes the normal "watch"
cursor to a cockroach?  This happened several times within ResEdit,
but disappeared after ResEdit was exited and could not be repeated.

The disk has been inspected with Disinfectant and SAM.  No viruses
were found.  I also checked for unknown INIT resources in the system
folder.  The same system was recently infected by nVIR.  Disinfectant
was used to eradicate it.

Any words of wisdom?
