How can I tell if Norton Antivirus 2009 is running properly?

Recently, I had recovered from a video card driver induced system crash and noticed that during odd reboots I fail to see the Nortion Antivirus icon in the system tray.  How can I tell if NAV 2009 is running properly?  Is there a list of system processes I should look for?  Is there a tool I can run to check?  Any help is appreciated.
