SONAR Protection

Symantec Online Network for Advanced Response (SONAR) identifies emerging threats based on the behavior of files. It detects malicious code before virus definitions are available through LiveUpdate and protects you from advanced threats.

You must be connected to the Internet to get real-time SONAR protection.

You can modify SONAR settings, including Network Drive Protection and Advanced Mode options.

How do I turn on Network Drive Protection?

Symantec recommends that you keep Network Drive Protection turned on to keep your network drives secure.

Turn on Network Drive Protection

  • In the Automatic Protection tab, under SONAR Protection, in the Network Drive Protection row, move the switch to On.

How do I configure SONAR Advanced Mode?

SONAR categorizes threats as high-certainty or low-certainty based on their behaviors. By default, SONAR blocks high-certainty threats. You can choose to block all low-certainty threats or receive notifications that let you allow or block detected threats. If you allow a threat, SONAR does not notify you if it detects the same threat again.

Configure SONAR Advanced Mode

  • In the Automatic Protection tab, under SONAR Protection, in the SONAR Advanced Mode row:

    • To block high-certainty threats and allow low-certainty threats, move the switch to Off.

    • To block high-certainty threats and receive notifications for low-certainty threats, move the switch to Automatic.

      This is the recommended setting.

    • To block high-certainty threats, and receive notifications for low-certainty threats with few suspicious characteristics, move the switch to Aggressive.

      This setting is highly sensitive and might cause legitimate files to be identified as threats. It is recommended for advanced users only.

How do I configure Remove Risks Automatically?

By default, SONAR blocks only high-certainty threats. You can change the settings to have SONAR block all threats or ask you to block or allow low-certainty threats when it detects them.

Configure Remove Risks Automatically

  • In the Automatic Protection tab, under SONAR Advanced Mode, in the Remove Risks Automatically row:

    • To block all threats, move the switch to Always.

    • To block only high-certainty threats, move the switch to High-Certainty Only.

      This is the recommended setting.

    • To ask for your decision when a risk is detected, move the button to Ask Me.

How do I configure Remove Risks if I Am Away?

By default, SONAR only blocks high-certainty threats when you are not using your computer. You can change the settings to have SONAR remove all threats or ask you to block or allow low-certainty threats when it detects them.

Configure Remove Risks if I Am Away:

  • In the Automatic Protection tab, under SONAR Advanced Mode, in the Remove Risks if I Am Away row:

    • To block all threats, move the switch to Always.

    • To block only high-certainty threats, move the switch to High-Certainty Only.

      This is the recommended setting.

    • To ignore threats when you are away, move the switch to Ignore.

How do I configure Show SONAR Block Notifications?

Use the Show SONAR Block Notifications option to turn on or turn off notifications when SONAR blocks a threat. For example, you can suppress notifications when you watch a movie or play a video game in full screen mode.

Configure Show SONAR Block Notifications:

  • In the Automatic Protection tab, under SONAR Advanced Mode, in the Show SONAR Block Notifications row:

    • Move the switch to Show All to notify you every time SONAR blocks a threat.

    • Move the switch to Log Only, to suppress notifications but allow you to see details of blocked threats in the Security History window.

      To access the Security History window, in the Norton main window, double-click Security and then click History.
