Not for performance reasons but it's nice to have an "Exit" option for AVs for many reasons I don't wish to go into here. Norton doesn't have it either. I know Kaspersky and NOD32 do. What about others? Avast, Avira, AVG, McAfee?
yup. Norton 2009 doesnt have "Exit" option it, but atleast it has "Game Mode".
GUI stays in taskbar with
red icon

had to turn off "Action Center" warning messages.
thanks for the instructions Frank.
btw, used Task Manager to stop "MsMpSvc" service under "Services" tab & then under "Processes" tab, "msseces.exe" -> "End Task".
(Disabled UAC)

No need to restart the service, just open MSE & it'll promt for "restarting" the service,
