@Tom6, Tom tom tom, i hate to see you say that. Well i hate to see anybody say that really. Its not just a windows issue, just like windows, every OS has security flaws. I think we forget sometimes that Windows holds the majority of the OS market share by an extremely large margin. Why would anybody write a virus for a smaller audience? Its like trying to go to the most 3rd world part of a country and try to sell them a mercedes at sticker price. It just dosnt make sense your not going to get many if any sales.
Fact of the matter is, there are viruses for every OS out there, (yes including macs) its just not so apparent because there are so few because it is such a smaller target area. Just wait till the one day comes (maybe in our lifetime maybe not) when windows looses the majority of market share, the viruses for other OSes will be higher then windows.
I will say this though, only an opinion to me, and a logical opinion in my mind. Who knows, that day may never come
