I used the Public Beta of Norton 360. I've described it as Norton
System Works on Steroids <g>

It contains a lot of the stuff that was in NSW like defragging and so
on and frankly I don't think that is really necessary.

I now use Norton Internet Security 2007 under VISTA (and XP Pro) and it
does what I want (well almost; I'm waiting for the ad-blcoking anti-
spam extension that works in XP but is not out for VISTA yet as far as
I know -- I must recheck).

I do not find that it holds back my computing. AVG is a heck of a lot
quicker but I don't like their interface, at least not in the free
version I was using first for VISTA.
