				O - Affects system run-time operation
				P - Corrupts program or overlay files
				D - Corrupts data files
				F - Formats or erases all/part of disk
				L - Directly or indirectly corrupts file linkage

Size Increase -	The length, in bytes, by which an infected
               	program or overlay file will increase

Characteristics - x - Yes
                  . - No

Disinfectors -	SCAN/D 	 - VIRUSCAN with /D option
             	SCAN/D/A	 - VIRUSCAN with /D and /A options
             	MDISK/P	 - MDISK with "P" option
              	All Others - The name of disinfecting program
           Note:
                  The SCAN /D option will overwrite and then delete the
                  entire infected program.  The program must then be
                  replaced from the original program diskette.  If you wish
                  to try and recover an infected program, then use the
                  named disinfector if available.
