Symantec recommends that your computer remains
connected to Internet to get the real-time protection
against threats and proactively detects unknown
security risks on your computer.
SONAR monitors your computer for malicious activities
through heuristic detections.
SONAR automatically blocks and removes
high-certainty threats. Norton Internet Security
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.
Turning off or turning on SONAR Protection
SONAR protects you against malicious code even before
virus definitions are available through LiveUpdate. By
default, SONAR Protection is turned on to proactively
detect unknown security risks on your computer.
When you turn off SONAR Protection, you are
prompted with a protection alert. This protection alert
lets you specify the amount of time for which you want
SONAR Protection to be turned off.
w
When Auto-Protect is turned off, SONAR Protection is
also disabled. In this case, your computer is not
protected against emerging threats.
To turn off or turn on SONAR Protection
