Metamorphic virus will be the trend in development of computer virus in the future.It is necessary to research the metamorphic technology and metamorphic engine of virus.The metamorphic theory and development of computer virus is generalized,then the basic structure and flow are analyzed,the detailed design of two metamorphic engines is brought forward,and the function and arithmetic of every module is introduced in those engines detailedly.It also makes a discuss on the key technology that must be resolved in the imple-mentation of metamorphic engine,including instruction uncovered technique,instruction dependency parsing technique and generation of random number.At last,it makes a test on virus' ability of opposing detection of anti-virus software after metamorphosing.
