COMPUTER SYSTEM AND METHOD WITH ANTI-MALWARE

PROBLEM TO BE SOLVED: To protect a computer platform from malware. SOLUTION: An IB agent 108 that operates from an OS kernel 106 protects a platform 100 by interaction with an OOB agent 110. The IB agent 108 operates under a distrusted OS environment. On the other hand, in cooperation with a manageability engine 140, the OOB agent 110 runs beneath the OS, e.g., in virtualized, trusted memory space that is not part of the OS memory space. A secure OOB channel includes a network interface 144 in the management engine 140 and a virtual redirect block 142. The network interface 144 provides the network interface for the service 122 to communicate with the platform, even when an OS is not active. The management engine 140 can communicate with the service 122, when a malware may have compromised the integrity of the IB channel. COPYRIGHT: (C)2011,JPO&INPIT
