Abstract
A method of detecting rogue software includes the step of creating a first database containing pre-calculated fingerprints for each file relating to typical operating systems and application software, wherein the pre-calculated fingerprints are calculated using one or more cryptographic formulae. The one or more cryptographic formulae are then used to calculate fingerprints of files on a computer system which is to be scanned for rogue software. The fingerprints calculated for the files on the computer system are compared with the fingerprints which are contained in the first database of pre-calculated fingerprints. Files on the computer system which may contain rogue software are identified by identifying files the calculated fingerprints of which do not correspond to the pre-calculated fingerprints which are stored in the first database.
