malicious? "Host process for windows tasks" in notification area icons

[Callender]

I don't have a clue what that is! I've never seen "windows detects "slow performance" and tries to switch aero"

What happens if you click or right click the exclamation mark?

It gives you the option to switch to aero when it appears. I only see one game I have do this, but when it does it shares the same triangular yellow exclamation mark. In the notification bar, I see a similiar triangle with the same entry as before.
