Windows Vista is not so reliable?

Microsoft largely profited from its claims; Windows Vista would be most reliable of Windows, and even less prone to the attacks than Mac OS X.
A new study carried out by a security company (thus not truly independent) serves to blacken this reputation so difficult to acquire. Vista is more sensitive to Malwares than the old Windows 2000 and not much more secure than XP.
The experts in this study consider that the attacks targeting Vista will multiply as it gains market share and will become thus more interesting to attack.
We believe that, no operating system, containing hundreds of thousands of lines of code cannot state that it is unattackable. One wants to arrive at this perfection; however quite simply, it is not possible. One can only hope that the modularity of Mac OS X and its UNIX origins make it less vulnerable and at least easier to patch in the event of the discovery of a dangerous fault.
