I have Norton Internet Security 2003 and Norton Antivirus 2003 on my Windows XP computer. Despite being woefully out of date, I've been quite happy with it.
A few days ago Norton Internet Security started giving me subscription messages (as in buy one now, use a credit card). I was under the impression that I already had a subscription, but apparently it ran out. In any event, it's five years old now, so it's probably a better bet to just buy the new version of Norton.
However, I have two concerns.
1) I hear Norton is impossible to uninstall, so I don't know if it's possible to uninstall Norton 2003 in order to make room for Norton 2007/8. I can't find any advice anywhere on upgrading Norton, probably because it's so incredibly simple, but there's no such advice for people with no computer skills. (For instance, will the "old Norton" remain on my hard drive, try to scan my computer and try to make me buy a subscription extension?)
2) I heard Norton 2008 isn't any good and I should buy Norton 2007. If Norton 2008 is bad, what is bad about it?
Bonus question: Is it possible to find out what kind of power supply I have without opening up the computer? I just bought a new video card and need a 350 W power supply. However, I don't know what type I have, and might have to buy a new one.
