Monitor file integrity using MultiHasher

This guide describes the use of MultiHasher, an integrity monitoring tool for Microsoft Windows that may be used to monitor data files for evidence of accidental or deliberate change. Unexpected file change may be a symptom of an underlying problem – that the storage media is beginning to fail, or that the system has been compromised and updates made by a non-authorised user. For this reason it is important to monitor the integrity of valuable files on a regular basis.
