Norton 360 running background scan even when CPU is 100% busy

I have Norton 360 and the background tasks that are supposed to be done while idle are now happening even when I'm not. I've even gotten the popup while I was typing a message in an IM. I have a Sony Vaio laptop with Windows 7 and an Intel Core i7. I was reading another topic where people were complaining about the popups which are annoying on their own. But to now be getting them when I'm clearly at my computer and it's active is a little ridiculous.
