Symantec Anti-Virus provides "real-time" anti-virus protection—any time a file is accessed SAV scans it for viruses before opening it. If you think your computer might have viruses that existed prior to the installation of SAV, or that you may have acquired a file containing a virus, running a system scan is a good idea. To do so…

1. Open SAV by double-clicking the SAV shield in the system tray.
2. In the left pane of the window, click the “Custom Scan” icon.

   

3. When Custom Scan appears in the right pane of the window, click the checkbox next to “Local Disk (C:)”, then click the “Scan” button.

   

4. The amount of time the scan takes will vary based on the size of your hard drive and the speed of your processor—it is not uncommon for it take over an hour.
   If viruses are identified they will be reported in a notification window that can be closed or left open. When the system scan has completed, close all SAV windows and you’re done.
