F-Secure Key CPU usage (Windows 8.1)

Modulator

Hi!

 

Is it essential for F-Secure Key to use CPU all the time? Earlier, it was using 11% on my Thinkpad T430s (Windows 8.1), but since it has dropped to 3% continuous usage on normal power plan (no significant throttling). In all these cases the window has been closed, so it's running on the background (in that little bottom right side section of taskbar, what's its name..). Is this really necessary? Is it somehow constantly monitoring it's contents to prevent tampering or what is it about?

 

Edit: Okay, there was already a topic about this but has not been handled by staff at all..
