History: The virus was first detected in Vienna in December, 1987. In
|
|||
|
|
April, 1988, this virus surfaced in Moscow at a children's summer
|
|||
|
|
computer camp run by UNESCO. Someone who didn't know of its prior
|
|||
|
|
existence in Austria gave it the name DOS-62, presumably because its
|
|||
|
|
method of indicating an already infected file is to set the seconds field
|
|||
|
|
of the time entry of the file to 62.<Note: Contributed by Y. Radai.>
|
|||
|
|
|
|||
|
|
Description of Operation: This virus is a memory resident virus. It
|
|||
|
|
infects COM files (including COMMAND.COM) as they are loaded and
|
|||
|
|
executed. The infected files increase in size by approximately 648
|
|||
|
|
bytes. Some infected programs will not run.
|
|||
|
|
|
|||
|
|
The first three bytes of the program are stored in the virus, and
|
|||
|
|
replaced by a branch to the beginning of the virus. The virus looks for,
|
|||
|
|
and infects, one COM file - either in the current directory or in one of
|
|||
|
|
the directories on the PATH.
|
|||
|
|
|
|||
|
|
One in eight files infected does not get a copy of the virus.
|
|||
|
|
Instead the first five bytes of the program are replaced by a far jump to
|
|||
|
|
the BIOS initialization routine. That is, in one out of eight attempted
|
|||
|
|
infections, the system will perform a warm reboot when the infected
|
|||
|
|
program is run.
|
|||
|
|
|
|||
|
|
Removal: To remove the virus, follow the instructions provided for the
|
|||
|
|
Jerusalem virus or run M-VIENNA.
