88 Monitoring your system's performance About System Insight technique to scan your computer. It scans all of the files on your computer against the signatures that it obtained during definition updates. When you use the StandardTrust or HighTrust profile, Norton AntiVirus follows the Whitelist technique to scan the files based on their confidence level. This way, Norton AntiVirus significantly reduces the time that is required to scan your computer completely for security threats. The Whitelist technique that Norton Insight uses also helps in heuristic detection of suspicious applications. Normally, the execution behavior of well-known applications appears identical to the execution behavior of unknown applications. Such behavior results in false identification of good applications as suspicious, and therefore, necessitates security applications to maintain a low heuristic detection threshold. However, keeping a low detection threshold does not provide a complete heuristic protection against malicious applications. Norton AntiVirus uses the Whitelist technique that helps maintain a high heuristic detection threshold. It excludes well-known applications from heuristic detection to prevent false detection of well-known applications and to ensure a high detection rate of malicious applications. Viewing the files using Norton Insight Norton Insight provides information about the Files of Interest that are available on your computer. Norton AntiVirus lets you view specific categories of files based on the option that you select in the Norton Insight Application Ratings window.
