Adaptive system behavior change on malware trigger

Abstract:

A hardware secured flag mechanism which is activated by trusted Anti-Malware (AM) software. Upon being activated, the information handling system takes action to reduce user exposure even if the AM software is subsequently subverted. In certain embodiments, the flag mechanism is only reset by user intervention at a BIOS or other off-line mechanism. In certain embodiments, the flag mechanism may only be reset via a signed unlock key stored on an external memory device such as a universal serial bus (USB) key.

Abstract(Chinese):

由可信防恶意软件（AM）软件激活的硬件安全标志机制。激活后，即使AM软件随后被颠覆，信息处理系统也采取行动来减少用户曝光。在某些实施例中，标志机制仅通过用户介入在BIOS或其它离线机制来重置。在某些实施例中，标志机构可以仅通过存储在诸如通用串行总线（USB）密钥的外部存储器设备上的签名解锁密钥来重置。
