Embodiment Construction

[0021] In some embodiments of the invention, the act of performing a system scan may be modified from a static set of actions performed during the scan to a set of diagnostic scans, which may be based on an evaluation of stored state information about the system to be scanned Turn this diagnostic scan on or off at runtime.

[0022] figure 1 is a functional block diagram of an illustrative example of a diagnostic system 100 embodying certain aspects of the present invention. The illustrated components of diagnostic system 100 may, for example, represent software modules residing in the memory of one or more computers. As shown, in some embodiments, an agent 102 running on a computer system (not shown) may be invoked to check the health of the system. In the illustrative example shown, agent 102 includes scan context evaluator module 104 , diagnostic scan module 106 , and scan result evaluator module 108 .

[0023] Diagnostic scan module 106 may, for example, be capable of pe...

Abstract

In some embodiments, a local agent on a target system may evaluate current and / or historical system state information from a store (either local or remote) and dynamically adjust the level of diagnosis performed during the scan based on the evaluated state information. Individual diagnostic scans may, for example, be enabled and disabled based on the context in the store, and each scan may update the context for further evaluation. By employing such an approach, systems with a low risk profile and lacking symptoms of a problem may be scanned quickly while systems that show signs of a problem or have a high risk profile may receive a more thorough evaluation.

Description

technical field [0001] The present invention relates to computer system scanning, and more particularly to system state-based diagnostic scanning. Background technique [0002] Software designed to scan a computer system to determine if it is in good shape requires a compromise between performance and thoroughness. In general, the more thorough the scan, the longer it takes to execute and the greater the impact on the system. Routine system scans are usually expected to be quick and unobtrusive. But complex problems in detecting systems, such as infections caused by low-level rootkit malware programs, may require deeper system inspections that negatively impact system performance. [0003] Current solutions typically only offer two levels of regularly scheduled system checks: a "quick scan" that has minimal impact on the system but is not thorough, and a "full scan" that is thorough but has a significant impact. [0004] A need exists for a solution that is more efficient...
