Abstract: An improved approach for classifying computer files as malicious (malware) or benign (whiteware) is disclosed. The invention classifies any computer file as malware or whiteware after using Bayes Theorem to evaluate each observable feature of each file with respect to other observable features of the same computer file with reference to statistical information gathered from repositories of known whiteware and malware files.

Abstract: Technologies related to mobile communication devices are disclosed. A mobile communication device is identified, including identifying a unique identifier associated with the mobile communication device. An application is stored in firmware of the mobile communication device. The application is executed at boot-up and periodically when the mobile communication device is operating. Executing the application includes checking with a service to ensure that the mobile communication device is confirmed to be operational, including providing the unique identifier to the service. A confirmation is received that the mobile communication device is confirmed to be operational, and when so, waiting until a next check time for further processing. Upon receiving an indication that the device is confirmed to no longer be operational, a script is executed that locks the device, including creating a password, locking the mobile communication device with the password, and disabling a USB port that is included in the device.
