norton is an absolute piece of junk, it seems to come pre-installed on virtually every system I end up having to go round to someones house to fix and it is the first thing i remove. I used to have it on my own system some 2 years ago until I started looking carefully at what processes were running and trying to trim my idle ram usage down, then I began to see what a horror of a program it actually is.
As for this whole business with google, norton and the like, I totally a agree with whats been said, its stupid, google are mad because the built in search would use microsoft's online search engine when doing a web search through vista instead of google's, well duh, of course it would, use a microsoft OS search tool what else should you expect.
And as for the norton complaint that really pissed me off learning about that some 6-8 months ago, I knew exactly why norton were complaining because if microsoft had been allowed to do what they wanted, norton would probably lose 50%+ of its business. Instead because of norton vista is not as secure as it could be.
Glad I've got a macbook to fall back on
