What is the best anti-virus for iPhone?

None. Unless you've jailbroken your iOS device, getting any type of malware is just short of impossible.

Yes, there is AV software in the App Store for iPhones and iPads, but they are, literally, 100% useless. They cannot in any way touch the OS, or even other apps. The only thing they can scan for malware is themselves.

None. Apple's sandboxing stops malware from affecting the OS, and also stops a scanner from checking anything other than its own documents.
