Recently I get the impression malware is only present on Android (compared to other mobile platforms) as every IT news magazine reports only on Android malware. (I guess it is also involved with the fact that mobil devices become more and more powerful and also mobile malware evolves => kind of populism) However, when I do web search indeed I get the impression that Android is the excellent platform for malware:
What do you think? Are those ratings biased?, Why? On the other hand Android is the most common mobile operating system making it an attractive place for malware. Additionally manufactors do not update their devices with newer versions (as they want to sell newer phones with newer android versions (fragmentation)). And last but not least the android market is some how not as restrictive as the iOS store, right?
And yes of course: classifying what actually is malware is not so clear, so it depends how and who is calculating "malware".
