Do you
really believe that Windows market share is the 'main reason' it's historically been such a security nightmare? Fact is, historically, Windows (and in fact Linux but more so Windows) has had tonnes of security vulnerabilities over the years due to a sloppy approach to security resulting in lots of security bugs (e.g. ActiveX in IE, WTF!?), while BSD has always had a much stronger focus on security and also has an excellent security record (one of the BSDs used to brag on their homepage "five years without a remote exploit in the default install" - not one! And BSD runs a lot of servers and a BSD branch powers all OS X systems). If it were really market share related, then why isn't Linux more vulnerable in a world where Linux has the biggest market share for webservers and the majority of hackers actually use Linux as their platform and most major hacking tools have historically run on Linux? Also, OS X has a bigger market share than Linux, so why are there more exploits for Linux than OS X if it's proportional to market share?
There is this myth (propagated by Microsoft propaganda) that exploits can simply be 'created' for systems and that this happens as a function of market share. It doesn't work this way, exploits cannot be created unless there is a
defect in a system that they can take advantage of (or use social engineering). A system
can have 100% market share and have zero vulnerabilities if it's written very well. In many cases major viruses and spyware spread through known defects for which there was no patch, and there will always be some time inbetween a vulnerability becoming known, and the patch being issued.
Do you apply the Security Updates ???.
Of course, and I have a firewall. I'm not sure what that's got to do with anything, unless you are genuinely making the suggestion that the only reason people are ever vulnerable on Windows is if they don't patch!
Well so can XP ... running Apache, MySQL and PHP on it to host WordPress.
Huh? You
completely missed my point here; I was stating yet another reason why you might legitimately need an antivirus on OS X (in response to the apparent implication that the existence of Norton for OS X must mean that there are Mac viruses): OS X can function as e.g. a mailserver for Windows clients, and thus
even though it itself is immune to all the e-mail viruses coming through it, you still want to
block any incoming e-mail viruses before the Windows machines collect them. (The fact that XP can also function as a server seems about as relevant a response as stating that the sky is blue, as it's already completely obvious why an anti-virus needs to exist for XP.)
