Q: Norton security - does my iPad Air need virus protection

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.

The biggest security vulnerability for an iPad is the person using it.

A virus, as defined as a malicious program that propogates itself across the operating system cannot run on an ipad since it has no file manager to corrupt. But if a user clicks on a bad link and enters their info on a bad site or other things like that....then an ipad is no safer than any other device.

An iPad gives its users an advantage, they just have to use it wisely.
