Unique Known Viruses - 323

Known Variants of Viruses - 625

Total Known Viruses - 948

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

NOTES

SCAN /D OPTION

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.

OVERLAY-INFECTING VIRUSES AND THE /A OPTION

If a virus infects Overlay Files (Item 7) Clean-Up should

be used with the /A option when removing the virus.

CRASH VIRUS

The 'Crash' virus (in all implementations we have encountered)

crashes when run. It is included since it is possible that

under other architectures than those tested, it might flourish.

GENERIC BOOT SECTOR [GENB] AND MBR [GENP] VIRUSES

The Generic Boot Sector and Master Boot Record (or partition table)

ID code is a routine used to detect unknown viruses--it is not the

name of a specific virus. If you have found such a virus on your

system, please forward a copy to McAfee Associates for analysis by

our technical staff prior to removal with the CLEAN-UP program.
