Whoops, sorry I missed this while scanning for info on "Mac Defender". I preface this with the advice that it is from a site with a vested interest in Apple product but that aside the points made in the article are well made. As I noted in the previous post, the point made in this article as well, is that "its the con, not the technology that is the issue of concern to computer users.
The article also provides balance and perspective regarding what mac users need to actually be concerned about as well as the relative status of Microsoft Windows 7 and Mac OSX operating system.
Some of the reader feedback is also of interest suggesting that the issue is less with the Tech side of computers but rather with the changing demographics of computer users as this quote by 'charlituna' on the site above suggests:
"An 80 year old Granny isn't likely to think twice about putting in her credit card for an antivirus program anymore than she would think twice about how Christian that nice sounding young man that sent her the email about his inheritance is. It isn't that the alarm systems are faulty or the burglars have figured out how to break them. No they just trick folks into not turning them on. And then clean them out".
