This is one of these things that I've got both opinions - I can't progress my views without contradicting myself.
I feel that OSX is a hell of a lot safer than Windows - but that is partly because of marketshare.
I need help on this one from people who know it all - I begin thinking, "it can't be that hard to create a program that say, deletes the contents of the application folder".
Is it this easy? Or would there be a whole load of permission problems required and OSX would just not allow it?
How about writing something like that for Windows - deleting everything in Program Files, would Windows not allow it (aside from the fact that it might not be able to delete open programs) or would it let the program do the damage?
Finding the holes in something like that can make it so easy to create a virus - make it an addon pack for say iTunes and someone will download it, run it and boom say goodbye to your applications.
Possible?
