Q: Do I need any type of protection like an antivirus on my mini ipad?

No As of now there is no known virus that affects the iOS operating system

You can still fall victim to phishing if you are unwise where you enter your info

You don't need antivirus or security software as long as you don't Jailbreak your iPad.

Currently there's no known virus affecting iPad.

You don't need anti-virus software and, in any event, there isn't any available anyway.
