Murcia.4651

Description Murcia.4651

It is not a dangerous memory resident partly encrypted parasitic virus. Being executed it searches for .COM files (except COMMAND.COM) in the subdirectory tree, then writes itself to the beginning of the file. The virus searches for the FLOWEROF.MAY file, and terminates the infection routine if that file is found. Next the virus hooks INT 8, 21h, stays memory resident, and when any file is executed, the virus searches for .COM files and infects them in the same way as described above.
Two months after infecting a computer the virus manifests itself in several ways. First, it creates the MURCIA!!.nnn file, where 'nnn' is the internal virus counter, then writes the text string to that file:
MURCIA (SPAIN): THE BEST PLACE IN THE WORLD!
WHERE THE PEOPLE MAKES VIRUSES FOR YOUR COMPUTER!
NOW, IN SPANISH:
¿SABES LO FACIL QUE RESULTARIA BORRARTE TODOS
LOS FICHEROS DEL DISCO? O MEJOR AUN: FORMATEARLO.
QUE PASES UN FELIZ DIA.

Then the virus manifests itself with a video and sound effects. The virus also contains the text strings:
BOYA_PARA_MOV
FLOWEROF.MAY COMMAND.COM MURCIA!!.003
