    About a month ago I noticed that my fan didn't stop spinning on my 07 Macbook for a long time, even when no applications were open. A restart always seemed to stop the issue, but after a while, and some CPU usage, the fan would just start back up again, non-stop.

    I started paying more and more attention to the Activity Monitor and noticed that even while I was doing nothing (every user application closed), User CPU % would be around 50%. I have no printer, so no open print jobs would be running. I reset my SMC controls periodically, but I just can't understand what would be forcing my computer to work so hard while I'm literally doing nothing. Even as I write this post, I can see that if I sort by CPU usage, only Activity Monitor and Safari are active, but in the stats section, it's constantly 40%-50% used.

    Does anybody know what is going on?

    Well activity monitor should tell you what is using that 50% CPU.

    That's the thing - if i sort by CPU - it only adds up to 7%-10% at the most, but the stats section (with the green/red bar-graphs) always reads much higher.

    Okay - here are a couple of screenshots - who can explain what is draining my CPU usage?

    Try changing the view from "My Processes" to "All Processes." See if that gives you a different list.

    The process isn't showing, do what Thiol said, and the offending process should/will be in there.

    That did it - it was iavd - my iAntivirus program. I guess I should update to the paying version (or just get another program).

    Alternatively you can remove it and just be on your way, as there aren't any viruses for OS X in the wild.
