Yes, Iím sure that Apple is more secure than many to most other software systems. But Iím equally certain that the criminals arenít going to give up given the size of the population they can aim at now. No, I donít think it will get as bad as it did with Windows for a time: but it could at the very least get very boring and annoying having to fight off such malware attacks on systems that have traditionally been free of them. And the seriousness of Appleís problem is that theyíre not, as yet at least, used to dealing with this particular problem. Quite apart from anything else there isnít the ecosystem of anti-virus software writers as there is for Windows.
