Stony Brook University users with the managed version of Symantec Endpoint Protection are automatically set up to have their computers scanned weekly. Users with the un-managed version need to manually scan for threats. To run an anti-virus scan, double-click the gold shield or Symantec logo in the system tray. This will open the Status dialog box. On the left side, click on Scan for Threats. There is an option to run one of two scans, either an Active Scan which checks the most-commonly infected areas, or a Full Scan which checks the entire computer. The full scan takes much longer, so more time is needed if you are going to do this. It is best to run an active scan first and if anything turns up, then run a full scan.
