Games bring up Norton window

Hi,

 

I have come across the following problem:

  • Norton antivirus 2010 runs as usual and is visible as icon in the systray (next to clock).
  • Whenever I start a game, the Norton program window is started and Norton also shows up on the task bar.
  • Since the game is in full screen, there is no interference, but when I close the game, the Norton program window remains, and I need to close it manually (X in the upper right hand corner).
  • While the Norton window is up, nothing is actually started, meaning it doesn't run any kind of system scan, it just opens and stays until I close it again.
  • I am using Windows 7, but have the same issue on my XP SP3 system.

When I start programs other than games, such as Internet explorer, I have no issues, and Norton stays closed in the systray.

 

Any help?
