This requires extensive computer science skills.  <\/p>\n<p>One of the most famous metamorphic viruses is Zmist (also known as Z0mbie.Mistfall)  Written by the Russian virus writer known as Z0mbie, Zmist was the first of its type to use a technology called \u201ccode integration.\u201d  In layman\u2019s terms, Zmist decompiles files to their smallest elements and then moves code blocks out of the way to insert itself. It then regenerates the file with Zmist hidden within it. Other famous metamorphic files include Win32\/Simile &#8212; also known as Etap and MetaPHOR. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>A metamorphic virus is a class of viruses that call to mind the movie \u2018Terminator.\u2019 One of the most infectious and complicated viruses, metamorphic viruses are capable of changing themselves by translating, editing and rewriting their own code.
