Kufanana nehutachiona hwakavharidzirwa nguva dzose, hutachiona hwepolymorphic hunobata mafaira nekopi yakavharidzirwa yeayo, iyo inogadziriswa ne decryption module. Panyaya yehutachiona hwepolymorphic, zvisinei, iyi decryption module inogadziridzwawo pakurwara kwega kwega. Utachiona hwepolymorphic hwakanyorwa zvakanaka saka hauna zvikamu zvinoramba zvakafanana pakati pehutachiona, zvichiita kuti zviome kwazvo kuonekwa zvakananga uchishandisa "siginecha". Antivirus software inogona kuiona nekuburitsa hutachiona uchishandisa emulator, kana nehuwandu hwehuwandu hwehutachiona hwakavharidzirwa. Kugonesa hutachiona hwepolymorphic, hutachiona hunofanirwa kuve neinjini mutalphic (inodaidzwa kuti "muting engine" kana "mutation engine") mune imwe nzvimbo, iyo inogadziriswa ne decryption module. Zvisinei, mune polymorphic hutachiona, iyi decryption module inogadziridzwawo pakurwara kwega kwega kwega kwega kwega.
