IMO, Mac and Linux are good since most viruses are made for Windows. However, if Windows is as good as PC Mag says it is, why does Micro$oft need to release patch after patch to fix problems that should have been beta tested and repaired? I use Linux and it works fine without patches. I had one attack and that is all. WinXP had attacks on it left and right. IMO, Windows will always be attacked even if it's not the most popuar OS because of it's bad security and bad PR Micro$oft has in general.
