ABSTRACT:
Files stored on a hard disk drive are scanned for a predefined pattern, such as a virus definition. For each one of a plurality of files, predetermined select portion(s) (e.g., likely sites of infection) are stored in a common file. After storing the predetermined select portions, the portions are tested without accessing the file to determine whether content of the predetermined select portion corresponds to the predefined pattern.
