The best antivirus apps for the iPhone

Funny thing about iOS antivirus apps — there really are no such explicitly labeled apps on the Apple App Store, and for good reason: iPhones, iPads, and iPod Touch devices that haven’t been jailbroken are not in any danger of getting infected with in-the-wild mobile viruses. With Apple in control of what gets installed on your iPhone via its App Store, you can rest assured that no app there can access the OS-level data required to infect your phone or kill viruses. Apple’s iOS doesn’t allow security apps to perform traditional virus scans.

While your iPhone is generally protected from run-of-the-mill viruses, there’s no such thing as 100% secure, especially in an era when cybercriminals are working overtime to create ingenious gateways into your system. Viruses are only one type of internet security threat. Network hackers, fake websites, spyware, adware, phone theft, and so much more, are still security threats to watch out for. So, apps that focus on eliminating security threats are a great idea. There are many such security apps, and we identify some high-profile user favorites.

Do I need antivirus software for my iPhone?

Unless you jailbreak your iPhone, you do not need specific antivirus software to protect it from malware. That’s because the iOS platform sandboxes apps inside a user partition that prohibits access to your iPhone’s operating system. This prevents apps from changing other apps, files, or processes. Viruses can’t infect iOS devices because they are powerless to act on an iOS device.

While there have been reports of iPhone security and privacy issues, such as a backdoor flaw in its Wi-Fi chip or an errant iCloud account, third-party antivirus apps will not help you out of that kind of jam. The best solution for avoiding malware is to install all iOS updates, which almost always include security fixes.

Antivirus apps for iOS are actually advanced internet security tools, which include a wide range of safety features to protect against threats like phishing links, insecure public Wi-Fi networks, data-stealing apps, browser trackers, and device theft.

Does Apple recommend antivirus software for the iPhone?

No, not specifically. Apple has built iOS and iPadOS as self-contained secure systems. With its method of sandboxing, iOS doesn’t let antivirus apps work because that software needs to hook into the operating system, which iOS doesn’t allow. Sandboxing separates each app from all other apps and from the system.

What should I look for when choosing an antivirus for my iPhone?

The best iPhone antivirus apps will identify a broad range of security risks, alert you to them, let you secure the contents of your device, find a lost or stolen device and lock it down, are easy to use, and are reasonably priced.

Will iPhone antivirus software work on the iPad?

Most security software designed for the iPhone will also work on the iPad and the iPod touch because they are all based on the current iOS. That said, you should check with each product to make sure that the app offers the protection you seek. There may be certain features that only work on iPhones.

Apple iPhone 14 Pro Andy Boxall/Digital Trends

I had a ton of hope when I splurged the equivalent of $1,700 on the iPhone 14 Pro last year, buying into the camera hype of the new 48-megapixel sensor, the snazzy Dynamic Island, and a faster chip. I was sorely disappointed, especially when I looked at the competition and noticed I was missing out on meaningful perks like a folded lens telephoto camera for a higher lossless zoom range. I was not alone in sharing the disappointment.
