Interesting although I can't help but feel ios gets so much more attention than wp it is at more risk..
Agreed; WP is inherently very secure, but it can also thank its low market share for not being a target.
I'm surprised that Android did as well as it did, even though it came in last. This article reported that Android has 60% of malware infections, which is significantly lower than its market share. I've seen other reports of 97%, which I find to be a bit more believable.
I can believe the 60% malware infections, not everything in the google play store is a malware driven menace; probably not including sideloading apps perhaps.
