A tamper resistant software Agent for enabling, supporting and/or providing various services (e.g., tracking assets; data delete 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. In another aspect, the servicing functions that the Agent performs can be controlled by a remote server, by combining generic sub-function calls available in the Agent. This programmable capability of the Agent allow its functionality to be extended based on server-driven commands.
