Why don't Apple/Google ensure AV/Malware protection is a default app? Why do we depend on Apple/Google protecting us from these big bad apps?

If not Apple/Google controlling it directly, I'd imagine there would be a reasonable market for malware/AV providers on mobiles, if not solutions provided by Apple/Google.

More to the point, why do you act as if malware protection has ever been effective and not just a resource drain?
