Perhaps that's the case, but if it is, then it seems clear that Apple's sandbox is far better than Android's as well. Also, approving apps does cull out a range of malware, because it is human- and computer-analyzed before entry. As I said previously, this has its downsides, but it does make it harder to get malware into the iOS App Store. Not impossible, but harder.
