Abstract
A method of scanning files for malware on a computer system. The method comprises detecting a file to be scanned for malware in the computer system, determining the file being a partial file that comprises only a part of the file content, searching for an original clean file associated with the partial file, wherein the original clean file is a full copy of the partial file, based on finding a candidate original clean file associated with the partial file, calculating a partial hash of the same length as the partial file for the candidate original clean file, and based on determining that partial hashes of the candidate original clean file and the partial file match, signalling a false alarm.
