This virus was first reported in October, 1989 by Uval Tal in Israel.
|
|
It infects the first COM file in the current directory, and will
|
|
re-infect it again and again. It infects no other files, and causes no
|
|
other damage.
|
|
|
|
It has been called the "stupid" virus because it is so ineffectual
|
|
compared to other viruses. For instance:
|
|
|
|
* It always installs in memory in the same location, at address
|
|
9800:100H
|
|
|
|
* Any program which attempts to use this memory location destroys the
|
|
memory-resident copy of the virus.
|
|
|
|
* It can only infect systems with 640K of memory.
|
|
|
|
* It can not reach across directories.
|
|
|
|
* It cannot determine if the file it is infecting has previously been
|
|
infected.
|
|
|
|
* It does no apparent damage to anything but the first COM file in a
|
|
directory.
