Question

why is a polymorphic virus difficult to detect?

Answer 1

These viruses are more difficult to detect by scanning because each copy of the virus looks different than the other copies. Basically, polymorphic code mutates while keeping the original algorithm intact. Code encryption is a common method of achieving polymorphism
