Total Known Viruses - 475

LEGEND:

Size Increase:
     N/A        - Virus does not attach to files.
     None       - Virus does not change file size (attaches to tag end of file)
     Overwrites - Virus overwrites beginning of file, no file size change
     All Others - The length in bytes by which a file will increase when infected.

Damage Fields:
     B - Corrupts or overwrites the boot sector
     D - Corrupts data files
     F - Formats or overwrites all/part of disk
     L - Directly or indirectly corrupts file linkage
     O - Affects system run-time operation
     P - Corrupts program or overlay files

Characteristics:
     x - Yes
     . - No

Disinfectors:
     CLEAN-UP   - CLEAN-UP universal virus disinfector
     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 options 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
               above-named disinfector if available.

               If a virus infects Overlay Files (Item 7) Clean-Up should
               be used with the /A option when removing the virus.
