Pretty much as in the title really.
(1) I've noticed from time to time Norton Security just stops responding. The systray icon still has the green tick but right-clicking it doesn't bring up the menu and double-clicking the desktop item does nothing so I have to reboot my laptop to get it working again.
(2) Also I've noticed that although it downloads/applies the virus definition updates itself it doesn't do so with Norton Security program updates and so I have to periodically run Live Update myself to try and get those.
Would appreciate any advice.
