You made an either-or proposition. Either you're secure or you're not. The responder nailed it correctly: the issue is not "secure/insecure". His example showed that it's a measure of utility. How much effort expended by Apple and its users is worth the probable reduction in botnets on that platform and their consequent damage? Because botnets are historically so rare on MacOS (9 or X) the utility equation has always been very much in the don't-worry-about-it category. Not so for (for example Windows).
Will this equation change significantly with the new botnet? I think it's unlikely, but I dunno. Regardless, all-or-nothing seems to be the wrong perspective from which to examine this problem.
I never mentioned Macs are more/less secured. All I am trying to say is w.r.t computer security the sense of being secure & letting your guard down is the most insecure thing. Its just not about Virus,Trojans , Worms etc .. its also about social engineering. I tell my mom don't open random links .. I don't mention if its on email or a webpage or if its on Windows or her Android phone.
