ABSTRACT:
The present invention enables a large number of files to be processed for evidence of malicious content, independently of the file system that maintains the files. The processed files can be obtained from live data or a point-in-time copy (e.g., a snapshot) of the data, based on mapping information that maps the files to the physical storage device. In one embodiment, a method involves accessing mapping information corresponding to a set of data. The mapping information maps at least a portion of a file to a physical storage location. The portion of the file can be read from the physical storage location using the mapping information, without accessing a file system. The portion of the file can then be analyzed for evidence of malicious content.
