My point exactly BigSky. Most home users in my opinion would be better served with a Mac. They really are more user friendly and harder to screw up.
Each situation is different. For example. Outlook Express is "defaulted" not to load images, scripts, and music within e-mails, unlike "yesteryear" when OE users experienced "content rich" e-mails in all their exploitative glory.
Windows Update provides yet another hurdle to overcome. When you first go there, you get a browser redirect error page that simply states that "Your browser security settings are set too high", and guides the user on how to allow ActiveX content from Microsoft only, to be allowed to install and execute.
My point is, one has to be savvy enough to understand all of that.
Symantec, is merely plugging their product, because they are in the business of making money.
