Nokia astounded everyone by making a huge announcement that they will adopt Windows Phone as the primary operating system foe its future smartphones. I think this is a remarkable announcement coming from the world’s largest mobile phone manufacturer.
While the vast majority of PC malware is written for Windows, Windows Phone 7 is an entirely different ballgame.
However the security model of Windows Phone 7 is quite different from Windows XP/Vista/7/et cetera, and includes features such as Application Certification, Isolated Storage, and Application Isolation. For example, third party applications cannot run in the background because of security concerns. Windows Phone 7 and XBOX are the only Microsoft platforms where applications must be pre-approved by Microsoft before users can run them. As a result, we don’t expect any major mobile malware outbreaks just because of Nokia’s partnership.
