About the Norton AntiVirus scans
and proactively detects unknown security risks on your
computer. SONAR identifies emerging threats based
on the behavior of applications. SONAR identifies
threats quicker than the traditional signature-based
threat detection techniques. SONAR detects and
protects you against malicious code even before virus
definitions are available through LiveUpdate.
SONAR monitors your computer for malicious activities
through heuristic detections.
SONAR automatically blocks and removes
high-certainty threats. Norton AntiVirus notifies you
when high-certainty threats are detected and removed.
SONAR provides you the greatest control when
low-certainty threats are detected. You can also
suppress the SONAR notifications by disabling the
Show SONAR Block Notifications option.
The View Details link in the notification alert lets you
view the summary of the resolved high-certainty
threats. You can also view the details under Resolved
Security Risks category in the Security History
window.
