Abstract: Aspects of the invention relate to a method, apparatus, and computer readable medium for determining software trustworthiness. In some examples, a software package identified as including at least one file of unknown trustworthiness is installed on a clean machine. A report package including a catalog of files that have been installed or modified on the clean machine by the software package is generated. Identification attributes for each of the files in the catalog is determined. Each of the files in the catalog is processed to assign a level of trustworthiness thereto. The report package is provided as output.

Abstract: A logical container may be created to facilitate the quick and efficient migration of one or more virtual machines from a source server to a destination server. The logical container may contain all of the files and state information related to the one or more virtual machines. The one or more virtual machines may be migrated by dismounting the logical container from a source server and mounting the logical container to a destination server. A management service may be include to facilitate batch migration of multiple virtual machines from a source server to a destination server.

Abstract: An install control module allows installation of a software application onto a computer in presence of malicious code that is attempting to prevent installation. A metamorphic installation program is generated randomly to be substantially unique using metamorphic stealthing techniques. The program can be installed and is executed on the computer. Identifying information in the metamorphic installation program is substantially disguised from the malicious code so the program is substantially unrecognizable. The software application is installed onto the computer, and the metamorphic program protects the installation to allow the software application to be installed without substantial interference from the malicious code. In another embodiment, installation occurs by booting a preinstall environment on the computer without running a primary operating system. The software application is installed offline without the primary operating system running and before malicious code present on the computer is executed.
