Norton Automatic Scans updates virus definitions and scans your computer regularly for a range of threats. If you disable Automatic Scans, have been offline, or suspect that you have a virus, you can manually run the following:
Quick Scan to analyze areas of your computer that are most vulnerable to threats.
Full Scan to analyze your entire system including less vulnerable applications, files, and running processes than those checked during a Quick Scan.
File Scan to analyze individual files or folders if you suspect that they are at risk.

Using the Scan Summary window, you can view the summary of the scan that your Norton product last performed. Your Norton product automatically takes appropriate action on any infected file that it detects during the scan. You can view the details of the virus scans in the Security History window.
If your Norton product cannot repair an infected file, the file is quarantined. This way, your Norton product prevents the infection from spreading and infecting other files in your Mac. You can find the quarantined item under the Quarantine category in the Security History window.
You can use the Done option to close the Scan Results window. For potentially unwanted applications, Delete button is enabled. You can use the Delete button to remove the application.
