It's bad enough that such software is totally useless, but it also keeps upgrading and harassing you to restart, as if it is reminding you that the app totally exists on your computer and it's useful (look, it's doing totally important stuff in the background, restart now or later?).

      I reboot my Mac about 3-4 times a year

I reboot my Linux once every 2 days (when the battery runs out, I shutdown as I've had surprises with hibernation, even on OS X). But my desktop is loaded in 20 secs or so.
