     Virus101 is the descendent of Virus-90, also written by Patrick
Toulme as an "educational tool". The virus employs an encryption scheme
to avoid detection. It infects COMMAND.COM and all other executable file
types (COM, EXE, overlay). Once it has infected all the files on a
diskette, it will infect the diskette's boot sector. The current version
only infects floppy disks.
