Detection of metamorphic viruses: A survey

Computer viruses are big problem for security. It is essential to differentiate between reproducing programs and its similar forms. Reproducing programs will not necessarily harm the system. Classification aspect of metamorphic viruses is an emerging issue of research. The orientation and expansion of metamorphic viruses is quite critical and general problem of finding metamorphic viruses is NP hard. In this paper emerging methodology are discussed with their efficiency and working pattern.
