Abstract

A computer network comprises a server computer and a plurality of local computer. Each local computer is provided with an engine program which monitors all file and peripherals and detects changes in the files or configuration. The results f the monitoring are used to create compressed information relating to the files and peripherals which is communicated to the server computer which stores previous s information relating to the files and peripherals of the local computers. The server computer compares the received information with the stored information in order to detect the presence of altered and unwanted files or changes in configuration. In this way both known and unknown viruses can be detected as can un-authorised use of the local computers.
