As usual there's a lot of hot air around - and most of it seems to be from the pc crowd. I'm not an american so I'm not sure what the kool-aid reference is to but I have used macs for a long time and don't seem to get these problems that people scream and shout about every year or so. I am only running snow leopard as I find lion to be a pain in the a*** and I don't have software update turned on so I do not have the latest of whatever apple are offering in the way of security updates (I have a very slow broadband as I live on the edge of the world so I cannot be bothered downloading a constant stream of anything let alone security updates).
But please do tell us all how you let this trojan in, I'm sure that would do others a load of good.
