Today I went into Harvey Norman to purchase something, and when I was paying they asked for my Airpoints number so I could earn points on my purchase. I took out my iPhone to get the number from my app, as I didn't have the card with me. As soon as the salesperson saw it, he started telling me how several customers had been into their services department lately because their iPhones had been hijacked and all their credit card information stolen from their iTunes accounts, and some people had lost money. He said they couldn't get into their phones and couldn't reset to factory settings to restore from backup, and it cost $300 for HN's technicians to restore access. He also said the virus affected their fingerprint readers. He claimed there was an article in The NZ Herald about it, and I should buy Norton Antivirus for Apple devices right away to protect myself.

Now, I've had a bad experience with Harvey Norman's computer department before, having previously been sold a cover they swore would fit my iPad (it didn't) that they then wouldn't give me a refund for - just store credit. I usually keep abreast of tech news and haven't heard of any such virus in recent weeks. So I told him I'd do my own due diligence and left it at that. Since getting home, I've tried to find the Herald article he mentioned, without success. All I can find is something from July that urges people to update to 10.3.3 to avoid the Broadpwn bug, and this recent article that state iOS devices aren't actually susceptible to viruses (if they're not jailbroken), and antivirus products won't work on them anyway. 

So... Does anyone here run antivirus on their iOS devices or was the salesperson trying to scare me into buying an unnecessary product?
