Maybe I should have put malware in quotes. I was generally referring more to the privacy invading, battery sucking, ad displaying, etc behaviors of the vast majority of applications. Which per wikipedia (and traditional usage of the term) makes them malware.

Apple/etc seem to be suck in the mindset of the various antivirus products before the advent of adaware/etc. So the products aren't strictly virus/trojans/worms/etc but they definitely fit the definition of malware and the end results are potentially just as bad. I would actually prefer any number of virus's over the some of the shenanigans the facebook app has been accused of.
