Add a gamer mode
I was just in the middle of intence action when my game crashed to desktop because F-Secure IS 2012 wanted to inform me some mundane information about it's status.
When I'm playing games or doing something as intence I would like to put everything else on the background. As I can just close my emails and instant messengers I would also like to suppress notifications from my antivirus too just for the purpose to concentrate on what I'm doing.
I suggest you add some easy way to make F-Secure "disappear" while I'm playing and then come back when I'm not. This applies not only the popups and messages, but all the processor time consuming background tasks it does too if possible.
