Which would you purchase, and why? Personally, I'm leaning towards towards internet security now that I have no firewall currently now that my router was replaced by a crappy Netgear gateway/cablemodem bastard child. However, I really need system tools like a Defragmenter. Does Utilities have a disk cleaning software? I know alot of people are bashing Norton, but its just easier to put on my mothers computer. -EDIT- I mean SystemWorks, not Utilities.
