A tamper resistant servicing Agent for providing various services (e.g., data delete, firewall protection, data encryption, location tracking, message notification, and updating software) comprises multiple functional modules, including a loader module (CLM) that loads and gains control during POST, independent of the OS, an Adaptive Installer Module (AIM), and a Communications Driver Agent (CDA). Once control is handed to the CLM, it loads the AIM, which in turn locates, validates, decompresses and adapts the CDA for the detected OS environment. The CDA exists in two forms, a mini CDA that determines whether a full or current CDA is located somewhere on the device, and if not, to load the full-function CDA from a network; and a full-function CDA that is responsible for all communications between the device and the monitoring server. The servicing functions can be controlled by a remote server.
