Seriously, now, thanks for all the replies.
I figured out it was Ad-Aware that was updating on its own.
I wish these programs were smart enough to ask you if you wanted to update now, before they bog everything down.
Yep, I have heard that Norton sucks, but this isn't my computer, so I have to live with it...for now.
Trust me, I made my recommendations pretty clear to go with something else besides Norton...like AVG instead.
