Apple Users Not So Safe; there's just not that many users for the crooks to bother!

That's the theme of an article I'm linking here.  All Mac users should read this.  I underline the web browser exposure.  Everyone, regardless of platform, is exposed to exploits that reroute your browser interactions to malicious servers.  The article talks about Safari.  I recommend Safari not be used, but that you use Firefox instead, installing Add-ons that provide security.  In Firefox, Tools.Addons and then Get Addons.
