1. A method for identifying malicious software in an executable file, comprising: dividing a portion of the executable file into a plurality of windows, each window of the plurality of windows comprising one or more bytes; applying to the one or more bytes of the plurality of windows a transformation function that provides a numerically comparable value for the each window; displaying graphically the numerically comparable value for the each window as a function of the each window; determining if a given numerical comparable value is a statistical outlier with respect to other numerical comparable values; and if the given numerical comparable value is a statistical outlier, identifying a window comprising the given numerical comparable value as the malicious software, wherein the statistical outlier has a value two standard deviations greater than the mean of the numerical comparable values.
