IVP (‘INSTANT VIRUS PRODUCTION KIT’) is a virus creation kit. It produces
viral assembler source of different virus types. The characteristics of
the IVP-based viruses are selected by editing a configuration file. There
are several options: infect COM, EXE or both; encrypted or not; INT 24h
hooking or not; COMMAND.COM infection or not; and other.
This generator looks like a minor version of the PS-MPC code
generator, as well as G2 virus constructor.
