It's a common misconception that Apple devices are impenetrable to viruses. While it's true that Apple has historically put more emphasis on security than other manufacturers, the operating system is not without its attackers.
Think of it like this: if you are going to create a virus, you'll probably aim for the machines with the least security. That way, your virus is more likely to succeed. So, for years, virus writers tended to steer clear of Apple, which had fewer devices and tougher defences than the likes of Microsoft and Android. But with over one billion iOS devices now out there, if the virus writers can break through, there's a huge pool of devices to steal information and money from.
Viruses (whether for Mac, iOS, PC or Android) all have one aim: to make money out of you. Some do this by stealing your login credentials, so they can take money from your financial accounts or retail accounts which are linked to them (like Amazon and PayPal). Others will use your smartphone to text or call premium rate services which you won't discover until you get a huge bill (and guess who owns that premium rate phone line?). Some will lock your device and hold its content to ransom. There are many techniques the hackers use, but with comprehensive security software in place, you don't need to worry.
So viruses which target Macs, iPhones, iPads and iPods do exist. They are just as dangerous as viruses targeting Apple's rivals, there are just fewer of them by comparison.
There are some simple steps Apple users can take to avoid becoming a target:
1. Update the operating system software as soon as you're asked
People often don't do this because they don't notice a difference after the update. And that's usually because it was to fix a flaw in the software which could be used to get access to your device. If you don't install the update, it's still an open door to hackers.
2. Use security software
Security software is needed for Macs. This not only stops malware and phishing attacks, but also provides content control. iPhones are certainly more secure than Android devices, but features such as browsing protection are useful additional tools you can benefit from. The good news is that TalkTalk has Macs and iPhones covered with the SuperSafe powered by F-Secure. Eight-device protection is £2 per month (and it's worth £99 a year). Log in to My Account, select the package you want and you will receive an email from F-Secure to install it on your device for full protection.
3. Think twice about jailbreaking your iPhone
Jailbreaking may give you access to more apps and themes, but it also opens your device up to attack. The XSSER iPhone virus discovered last year would take SMS messages, stored photos and contacts. But it only worked on jailbroken devices.
