Concerning the spread of viruses from diskettes which contain no
DOS executable files, e.g., *.EXE, *.COM, *.SYS, and *.BAT
files, I understand that the only ways that a virus can spread from
this diskette is if

(1) a boot track, or partition table virus, is present, and the
computer is booted from this diskette,

(2) executable virus code is contained under the guise of a data
or text file, and is renamed to a *.EXE, *.COM, or other such
executable file and subsequently executed,

(3) executable virus code is hidden in a WordPerfect, 123, or other
macro.

Am I correct in my understanding?

Thanks in advance for any assistance.
