; Virus Name : Paradise
|
|
; Virus Author : Billy Belcebu/iKX
|
|
; Origin : Spain
|
|
; Platform : Win32
|
|
; Target : PE files
|
|
; Compiling : TASM 5.0 and TLINK 5.0 should be used
|
|
; tasm32 /ml /m3 paradise,,;
|
|
; tlink32 /Tpe /aa /c /v paradise,paradise,,import32.lib,
|
|
; Notes : Not very innovative, just made for practice some things, as
|
|
; CRC32 GetAPI engine, and such like. The name comes from one
|
|
; of the best songs i've ever heard, and probably my favouri-
|
|
; te song of Stratovarius. Its lyrics are, sadly, an actual
|
|
; reality: we are killing the nature slowly and without any
|
|
; kind of mercy, thinking that we can make any use of every-
|
|
; thing around without any responsability...
|
|
; Greetings : It is very clear... to all the Stratovaius fans (specially
|
|
; to Int13h and Owl) and all the ecologist activists.
|
|
; Fucks : To everything related to the bullfights, the greatest act
|
|
; of the human barbarism with the animals, the spanish's
|
|
; national shame; and to all the acts that go againist the
|
|
; rights of the animals and/or the vegetables, as well as
|
|
; with the persons (goddamn fascisms!).
|
|
;
|
|
; Rojo, sangre
|
|
; un color muy nacional
|
|
; morbo, suerte
|
|
; sol y arena pide Dios
|
|
; arte, muerte
|
|
; sirve de alimento
|
|
; pase, valiente,
|
|
; y vuelta al ruedo!!!
|
|
; Cuando el acero me traspasa el corazon
|
|
; y se le llama fiesta
|
|
; y otra vuelta de tuerca
|
|
; cuando el sadismo se convierte en tradicion
|
|
; y la faena en gesta
|
|
; y nadie se molesta
