A polymorphic virus is a virus that changes its virus signature (i.e., its binary pattern) every time it replicates and infects a new file in order to keep from being detected by an antivirus program. Data types and functions are included in polymorphism, and functional programming languages widely use this type of computing technique. Polymorphic viruses are complex file infectors that can create modified versions of itself to avoid detection yet retain the same basic routines after every infection. Rather than use an explicit decryptor in each mutation, Crypto virus (Win32) decrypts its body by brute-force key search !
