I will not delete this post.
I am not LW. But even if I was, I would still not delete it.
Why?
Because you don't know what you're talking about.
What happened to your cousin is regretable and I'm genuinely sorry, but, frankly, he should have known what not to download as I said in my other post.
To contract a trojan, your cousin must have downloaded an .exe or .zip file (sometimes .jpg or even .avi) and then tried to open it without scanning it first.
Besides, posting in the Mac sections is entirely useless: to this day, there are virtually no Trojans on this platform (although it has been proven that it is possible to create one)
