Norton 2008 is very light on resources from what I have experienced. My processor stays below 10% usage when idling and almost never tops 20% when surfing the web or listening to music. Right now, as I type this, there are 4 processes running that are tied to Norton in task manager....together they consume ~5 MB of RAM. And yes, I clicked "Show All Processes" and that's what I got. Doesn't seem to heavy on resources to me.
