Per fare ci\u00f2 il virus polimorfo cifra il proprio codice utilizzando a ogni infezione una chiave diversa. Questo software \u00e8 dotato di una routine, anch’essa cifrata, che ha il compito di decifrare la parte del codice relativa al virus vero e proprio e di creare routine diverse dalle precedenti spesso introducendo istruzioni fatte per sviare gli antivirus, e trasformando i blocchi di codice al fine di non essere riconosciuti pur mantenendo le stesse funzionalit\u00e0.<\/p>\n","protected":false},"excerpt":{"rendered":"
