- The Michelangelo virus is spread by booting from an infected floppy
- diskette. When the infected floppy is booted from, the virus code is
- loaded and executed by the computer. The virus is now installed in
- memory and will monitor the system for disk accesses. When a disk
- access occurs, the virus checks the disk to see if its infected, and
- if not, infects the disk (network drives, Stacker compressed volumes,
- and other media which are accessed through a device driver are not
- affected). I recall that the first copy of the virus we saw did not
- infect the second disk drive, however, a later version (February or
- March of this year?) infects both floppy drives.
