Product manual

Norton 360 also provides different profiles to configure
your scan performance. When you use the Full Scan
profile, Norton 360 follows the Blacklist 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 Standard Trust
or HighTrust profile, Norton 360 follows the Whitelist
technique to scan the files based on their confidence
level. This way, Norton 360 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 360 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
360 lets you view specific categories of files based on
the option that you select in the Norton Insight -
Application Ratings window.
