No surprise here.... Security companies will try to exploit this incident as much as possible, lets not forget that they have a real financial interest in this matter and let us much Mac users as possible know that their OS can be/get infected.
I'm still surprised on how sophisticated this attack was and wonder which cyber criminal would have wasted so much resource into building it...
Truth be told , I wouldn't be surprise if in 10 years , when all the MAC's will come pre-installed with an AV ,we would hear that the first successful virus for MAC was created with some marginal and indirect help from the security companies..
Of course if you have a MAC and suspect an infection.. run this tools and then use an antivirus to secure your system..
