Many of you think c is useless for viruswriter. Many poeple wich start vxing handle better c language than assembly one. But the true reason where C is locked for virus is the dependency of the compiler, wich block some special manipulation. But the use of a C compiler is not totally senseless. If the optimization is not perfect, it can build a code very proach and similar to the assembly one, if you follow some rules. Of course, you will loose a few size, but you will gain by stability, portability, and finally by coding much fastly your nice littles routines, that you may customize once in assembly.
