Abstract: The claimed subject matter is directed to the use of an application reputation service to assist users with minimizing their computerized machines' exposure to infection from malware. The claimed subject matter provides an application reputation service that contains the reputations for elements that are known to be non-malicious as well as those known to be malicious. One embodiment is implemented as a method to determine the reputation of an element (e.g., an application). When a user attempts to install or execute a new application, the Application Reputation Service is queried by the user's machine with a set of identities for the element. The reputation of the application is determined by referencing a knowledge base of known reputations and returns an indication (e.g., an overall rating, or a flag) of how safe that application would be to install and run on the user's computer.

Abstract: Systems and methods are provided for improved filtering and correcting of glyphs on a GPU. The computational intensity required for filtering and/or rendering can be reduced by pre-calculating some or all of the calculations needed for converting coverage data into corrected pixel values. Additional efficiencies may be realized in some embodiments by transferring data from a CPU to a GPU in an improved format. The improvements can be realized in a variety of graphics formats.

Abstract: A method for managing changes to policies in an enterprise includes receiving a systems policy change request to change a systems policy that implements a published enterprise policy, determining whether the requested systems policy change complies with the published enterprise policy, and updating the systems policy according to the requested systems policy change if the requested systems policy change complies with the published enterprise policy. A system for managing policies in an enterprise includes a policy management module configured for receiving published policies and generating corresponding systems policies having data for implementing the published policies, and a policy library storing the published policies and the systems policies.

Abstract: The present invention provides a method and computer-readable medium for searching for programming objects on a computer system. Under one aspect of the invention, optional search attributes are used to order a list of references to found programming objects. Under a second aspect of the invention, object attributes that are stored outside of a static attribute storage area are inspected during the search for programming objects.

Abstract: The present invention provides the ability to compare and enforce policies between trusted entities within a rights management system. For example, policies between the two entities may be received by either entity. They may then be compared to determine the compatibility of the two policies. If compatible, or maybe even without the comparison, other embodiments provide for message server use license, which allows access to the protected portion of a message, thereby permitting an entity to enforce its message policies.

Abstract: A method and system for transparently combining remote and local storage to provide an extended file system such as a virtual local drive for a computer system client/user, e.g., a user of a pocket sized personal computer or a cable set-top box. A client device may load file system object data, storing the directories and files remotely, and retrieving the files only when required. Via its local storage, the extended file system handles unreliable connections and delays. When a connection to an extended file system server is present, the extended file system provides automatic downloading of information that is not locally cached, and automatically uploading of information that has been modified on the client. Extended file system attributes are employed to determine the actual location of file system data, and a lightweight protocol is defined to download or upload remote data by low-level components that make the remote source transparent from the perspective of the application.
