|
|
|
|||
|
|
Date of Origin: January, 1990.
|
|||
|
|
|
|||
|
|
Place of Origin: Taiwan, R.O.C.
|
|||
|
|
|
|||
|
|
Host Machine: PC compatibles.
|
|||
|
|
|
|||
|
|
Host Files: Not memory resident. Infects COM files, including
|
|||
|
|
COMMAND.COM.
|
|||
|
|
|
|||
|
|
Increase in Size of Infected Files: 708 or 743 bytes.
|
|||
|
|
|
|||
|
|
Nature of Damage: corrupts COM files.
|
|||
|
|
|
|||
|
|
Detected by: Scanv56+, F-Prot.
|
|||
|
|
|
|||
|
|
Removed by: CleanUp, Scan/D, or delete infected files.
|
|||
|
|
|
|||
|
|
Whenever this virus is activated, it attempts to infect up to three
|
|||
|
|
COM files. The search for uninfected COM files begins in the root
|
|||
|
|
directory of C:. Once an uninfected COM file is located, the virus
|
|||
|
|
infects the file by copying the viral code to the first 743 bytes of the
|
|||
|
|
file, relocating the original first 743 bytes of the file to the end of
|
|||
|
|
the COM file.
|
|||
|
|
|
|||
|
|
If the COM file selected for infection is less than 743 bytes, the
|
|||
|
|
resulting infected COM file will always be 1,486 bytes in length. This
|
|||
|
|
"bug" results from a failure to check for the original file length.
|
|||
|
|
|
|||
|
|
The virus is destructive. On the 8th day of any month, when an
|
|||
|
|
infected program is run, the virus will perform an absolute disk write
|
|||
|
|
for 160 sectors starting at logical sector 0 on the C: and D: drives,
|
|||
|
|
overwriting the FATs and root directories.
