Definition Edit

A self-recognition procedure is

a technique whereby a virus determines whether or not an executable is already infected. The procedure usually involves searching for a particular value at a known position in the executable. Self-recognition is required if the virus is to avoid multiple infections of a single executable. Multiple infections cause excessive growth in size of infected executables and corresponding excessive storage space, contributing to the detection of the virus.[1]
