This virus was discovered by Jean Luz, an NCSA member in Lisbon,
|
||
Portugal, in November, 1989. It infects COM files and increases the size
|
||
of infected programs by 648 bytes. It destroys 1 out of 8 infected
|
||
programs by overwriting "@AIDS" on top of the first five bytes of the
|
||
infected program.
|
||
|
||
The virus is very similar to Vienna, except that almost every word in
|
||
the virus has been shifted 1-2 bytes in order to avoid virus
|
||
identification/detection programs which could identify the Vienna
|
||
virus.
