  • Patent number: 10437997
    Abstract: Techniques are provided for the detection of malicious software (malware) on a general purpose computing device. A challenge in detecting malicious software is that files are typically scanned for the presence of malicious intent only once (and subsequent rescanning is typically performed in a simplistic manner). Existing methods in the art do not address how to most effectively rescan collections of files in a way that tries to optimize performance and efficacy. These methods may also be useful if additional information is now available regarding a file that might be useful to an end-user or an administrator, even though the file's core disposition might not have changed. More specifically, we describe methods, components, and systems that perform data analytics to intelligently rescan file collections for the purpose of retroactively identifying malware and retroactively identifying clean files.

  • Patent number: 9639697
    Abstract: A system retroactively detects malicious software on an end user system without performing expensive cross-referencing directly on the endpoint device. A client provides a server with information about files that are on it together with what it knows about these files. The server tracks this information and cross-references it against new intelligence it gathers on clean or malicious files. If a discrepancy in found (i.e., a file that had been called malicious, but that is actually benign or vice versa), the server informs the client, which in turn takes an appropriate action based on this information.

    Abstract: The present invention relates to the security of general purpose computing devices, such as laptop or desktop PCs, and more specifically to the detection of malicious software (malware) on a general purpose computing device.

Existing methods in the art do not address how to most effectively rescan collections of files in a way that tries to optimize performance and efficacy. Accordingly we present novel methods, components, and systems for intelligently rescanning file collections and thereby enabling retroactive detection of malicious software and also retroactive identification of clean software. These methods may also be useful if additional information is now available regarding a file that might be useful to an end-user or an administrator, even though the file's core disposition might not have changed.

  • Patent number: 9218461
    Abstract: Novel methods, components, and systems that enhance traditional techniques for detecting malicious software are presented. More specifically, we describe methods, components, and systems that leverage important contextual information from a client system (such as recent history of events on that system) to detect malicious software that might have otherwise gone ignored. The disclosed invention provides a significant improvement with regard to detection capabilities compared to previous approaches.

  • Patent number: 9100425
    Abstract: Novel methods, components, and systems for automatically detecting malicious software are presented. More specifically, methods, components, and systems for the automated deployment of generic signatures to detect malicious software. Even more specifically, computer implemented methods for determining whether a software application is likely malicious including computing at a client component a generic fingerprint for a software application, transmitting the generic fingerprint data to a server component, receiving at the client component information from the server component relating to the generic fingerprint of the software application, and following a prescribed set of actions based on the information received from the server.

  • Publication number: 20140188986
    Abstract: The present invention relates to the security of general purpose computing devices, such as laptop or desktop PCs, and more specifically to the detection of malicious software (malware) on a general purpose computing device. A challenge in maintaining a plurality of computing systems is that it may be required to have visibility into the extensive collection of computing related resources located across those systems as well as information about resources together with their behaviors and evolutions within those systems. Examples of such resources include files, file names, registry keys, entries in network communications logs, etc. Accordingly, we present novel methods, components, and systems for keeping track of information about these resources and presenting this information to an ultimate end user.
