I am running Microsoft Security Essentials (MSE) 2.0 on Windows XP SP3. It gives me an amazing feeling and I am really happy with its performance. However the only problem that I have noticed with MSE is that most of the time, twice in a week, my system tray icon gets vanished. I have checked the settings just to make sure it is not set to hide when it is running. But I am not hiding the icon and MSE is still working. Then why there is no tray icon. How can I add the MSE icon to the system tray? Any ideas? Is there anyone else who got this problem?
