How to Prevent Malware on iPhone, iPad or iPod Touch

Introduction

Malware is software that is specifically designed to disrupt, damage, or gain unauthorized access to a computer system. While malware is prolific among Windows machines, it is very difficult to infect an iOS mobile device. This is because everything you do on these devices is done in what is known as a sandbox or a protected area. 
However, you may run into the browsers on your iOS, whether you use Safari or Chrome, having a malicious pop up or browser hijack.
This guide will explain malware and how it relates to and can be prevented on iOS devices.

Are my iOS devices at risk?

Any apps you install on your iPhone run in a sandbox that limits what they can do. Apps can only access data that you give them permission to access.

In short, an iOS device won't do anything you don't want it to do. Most complaints about malware on iOS are about bugged apps or hijacked browsers.

Your iOS device will be one of the most secure devices you can have, as long as you know how to keep it safe.

Jailbreaking

This can put your device at risk.

Why Backup
Time Machine Preferences First and foremost, it is always wise to backup you data and backups should be performed regularly. Even beyond the scope of malware or security, it is always prudent to have frequent backups because hard drives can fail, systems can crash, things can break, "life can happen", so you're always better off safe than sorry.
iCloud
iCloud PreferencesiCloud has been the default way to backup your iOS devices since iOS 5. The first 5GB of files you backup using iCloud are free. Once this has been filled up, you'll have to pay a monthly fee. Photos and videos can fill up your free 5GB fast. If you take a lot of pictures, you may need to consider upgrading your iCloud storage, or backup using iTunes instead. 
iTunes
iTunes. To backup using iTunes, you will need to connect your device to your computer. You'll be using the USB cable that it came with to do this. While this method is free, it is not automatic and will take some time to download all of the data on your device over to your computer. If you want to use iTunes with your computer, you can set it to encrypt your data for extra protection.
