ABSTRACT:
Scanning of a file for malware is performed by prefetching data needed for the scan. The sequence of data to be prefetched is determined based on a previous malware scan of the file. Logical prefetching functionality is used to monitor a sequence of data accesses during the previous malware scan. The sequence is saved and is then later usable to prefetch data in anticipation of a next malware scan of the file.
