The 3 Best Antivirus for iPhone & iPad (2023 Update)

By Tibor Moes / Updated: September 2023

Apple iOS is a digital fortress. The App Store has a strict review process for new apps. And on iPhones and iPads, each app is isolated in a personal sandbox, keeping it separate from your sensitive data. But that’s not the whole story.

  • The digital realm is full of potential pitfalls. For instance, phishing scams lurk in emails, texts, and websites. And even the iOS system isn’t immune to undiscovered zero-day vulnerabilities.
  • Public Wi-Fi networks can be incredibly unsafe. Anyone who shops, socializes, and banks on their phone should have a VPN. It will encrypt your internet connection and keep your data safe on public Wi-Fi.
  • Finally, your sensitive information might have already been hacked in a data breach. These happen all the time. A dark web monitor will scan the dark side of the internet for any misuse of your personal data.

Investing in an antivirus app isn’t just about getting a piece of software. It’s about safeguarding your peace of mind. Embark on your digital journey with the confidence that you’re protected every step of the way.

Norton Mobile Security for iOS Review

Norton Mobile Security for iOS is the best antivirus for iPhone and iPad.

  • The Unlimited VPN will keep your personal information private online.
  • The Anti-Tracker will stop ads from following you across the web.
  • The Web Protection will protect you from dangerous websites.
  • The Identity Protection will monitor the Dark Web for your data.
  • The Device Protection will keep you informed on security updates.

In short: Norton will significantly improve your online security and safeguard your privacy and identity. It’s the best security app for iOS of 2023.


A VPN (Virtual Private Network) hides your iPhone’s IP address and encrypts your internet connection. This has several advantages:

  • You’ll be anonymous online. A VPN will hide everything you do online from governments, Internet Service Providers, Facebook, hackers, and more. You can search, surf, socialize, and shop in anonymity.
  • You are safe on public Wi-Fi. Typically, public Wi-Fi networks are unsafe. However, because a VPN encrypts your internet connection, other users on the network (including hackers) can’t see what you do online.
  • You can avoid censorship. In some countries, specific websites are blocked (for instance, WhatsApp calls in Dubai or YouTube in China). You can avoid these restrictions and use those services by using a VPN.

The best thing about Norton’s Secure VPN is its unlimited data. VPNs offered by other brands usually have a data limit between 200 and 500 MB / day, which means that you can’t leave the VPN on. Instead, you’ll have to use it tactfully and, most importantly, not forget to turn it on.

With Norton, you can turn the VPN on once and forget about it. From that moment forward, you will be anonymous online. Forever.

Ad Tracker

The ad tracker is part of Norton’s VPN. When the VPN is activated, the Ad Tracker will block cookies that attempt to track your activity online.

Web Protection

Norton’s advanced Web Protection will detect and block dangerous sites before you visit them. It works with any iOS browser and can be activated with or without the VPN. Of course, we recommend turning on both simultaneously to maximize your protection from online threats.


Did you know that there is a hidden part of the internet that search engines can’t find? It’s called the Dark Web, and cybercriminals use it to buy and sell personal data, like credit card information. Norton can search the Dark Web to see whether criminals are trading your personal data.

It can monitor your:

  • Email addresses
  • Home addresses
  • Phone numbers
  • Credit cards
  • Bank accounts
  • Insurance information
  • Driver’s license
  • Mother maiden name
  • And even your Gamer tag

Device Security

Norton will check whether you have updated your iPhone or iPad to the latest iOS version. As newer versions are frequently security updates, they are critical. Interestingly, we often learn about a new update for iOS from Norton and not from our iPhone itself. So it’s a helpful feature.

Wi-Fi Security

Norton will check whether your Wi-Fi connection is password protected and encrypted. If you have the Auto-Connect feature of your VPN activated, it will automatically start the VPN if you connect to a compromised network.

SMS Security

Norton can filter dangerous text messages containing phishing links to malicious sites that attempt to steal your personal information.

Secure Calendar

Norton will identify iOS Calendar invites that contain dangerous links.

Is Norton Mobile Security for iOS the best antivirus for iPhone?

Yes, we believe it is. Unfortunately, most antivirus apps for iOS devices offer minimal benefit to Apple’s highly secure mobile operating system.

Norton is different. By combining an Unlimited VPN with Web Protection, Anti-Tracking, Identity Theft Protection, and a range of bonus features like Device Security, it is a truly valuable addition to the native security of iOS.

And compared to its rivals, McAfee and Kaspersky, Norton has no weak spots. Norton is far cheaper than Kaspersky, and Norton does not limit your VPN data when you turn of auto-renew (like McAfee does).

So it’s an easy conclusion: Norton is the best antivirus for iPhone.

You can try Norton risk-free, thanks to its 60-day return policy.

What is antivirus software?

Antivirus software is a set of programs designed to safeguard your computer or mobile device against various forms of malicious software, often referred to as ‘malware.’ These can include viruses, worms, ransomware, spyware, adware, and Trojan horses, among others.

The primary role of antivirus software is to detect, neutralize, and remove these threats before they can harm your device or compromise your data. This software helps maintain the integrity of your system, protect your personal information, and ensure smooth, secure online interactions.

For more, read our blog post on what antivirus software is.

How does antivirus software work?

Antivirus software operates using complex algorithms and multiple detection techniques to identify and eradicate potential threats. It continuously monitors your computer for suspicious activities and scans files or directories for any signs of malware. Here are three of the primary methods that antivirus software uses to protect your system:

Signature-based detection

Signature-based detection is one of the earliest and most common methods used by antivirus software. It works by comparing potential malware against a database of known malware ‘signatures’. Each piece of malware carries unique identifiers or signatures. The antivirus scans your files and matches them against its signature database to identify any threats.

This method is highly effective at detecting known threats but can struggle with new, unknown malware.

Heuristic analysis

To overcome the limitations of signature-based detection, antivirus programs use heuristic analysis.

This method is designed to detect previously unknown threats or new variants of existing malware. Heuristic analysis does this by examining the attributes and behaviors of files and code to identify potentially malicious activity. For example, if a program is trying to write data to an executable file, the heuristic scanner may flag this as suspicious behavior.

Behavior-based detection

Behavior-based detection, also known as behavioral analysis, observes the behavior of software applications in real-time. It flags unusual or suspicious activity, such as unexpected system modifications, attempts to access sensitive information, or the alteration of system settings.

This method is particularly effective against zero-day threats – new, previously unseen malware that doesn’t yet have a known signature. When behavior-based detection spots unusual behavior, it can stop the suspicious program in its tracks, protecting your system from potential harm.

Does iOS need antivirus software?

Yes, while iOS devices are widely regarded for their robust built-in security measures, it’s essential to understand that they are not completely impervious to threats.

Apple’s stringent app review process and its policy of ‘sandboxing’ (isolating apps within their own operating environment) significantly reduce the risk of malware. However, this doesn’t eliminate the potential for cyber threats entirely. For instance, if an iOS user clicks on a malicious link in an email or a text message, they could still fall victim to phishing attacks, identity theft, or data breaches.

Moreover, the increasing sophistication of cyber threats means that hackers are continually seeking ways to exploit vulnerabilities, even in secure environments like iOS. Zero-day vulnerabilities, which are previously unknown software bugs that hackers can exploit before they are patched, represent a constant threat.

Besides, security apps offer features beyond just malware protection. They include VPNs for secure browsing on public Wi-Fi networks, safe browsing tools to protect against phishing attacks, identity theft protection, and even features for device performance optimization.

In summary, while iOS devices have strong built-in protections, the addition of a quality security app offers an extra layer of protection and peace of mind. It can help to fend off the evolving array of online threats and protect your personal information from being compromised.

For more, read our blog post on whether iOS needs antivirus.

What are the built-in security features of iOS?

The security of iOS, Apple’s mobile operating system, is notable for its robust, multi-layered approach. This security is often a key selling point for Apple devices. Let’s delve into these features, breaking them down to their core components while ensuring our explanation remains accessible.

Hardware-based Security

  • Secure Enclave: A dedicated coprocessor in Apple devices, the Secure Enclave, plays a pivotal role in data protection. It’s responsible for processing fingerprint data from the Touch ID, facial data from Face ID, and securely managing cryptographic keys. Because it’s isolated from the main processor and the rest of the device, it offers an added layer of security.
  • Device Integrity Checks: On boot-up, Apple devices perform a series of integrity checks, ensuring that no unauthorized modifications have been made to the software.

Software-based Security

  • iOS Sandboxing: Every app runs in a restricted environment, or ‘sandbox’. This means apps can’t access the data of other apps or tamper with the system itself. If an app becomes compromised, the damage is confined to its sandbox, preventing widespread harm.
  • Code Signing: Only apps signed by Apple can run on iOS devices. This ensures the authenticity of apps, protecting users from malicious software.

Data Protection

  • Encryption: iOS employs end-to-end encryption for data both at rest and in transit. Meaning, whether you’re storing photos on your device or sending an iMessage, your data remains private.
  • Touch ID and Face ID: Biometric authentication methods provide users with a secure, convenient way to unlock devices, make payments, or authenticate app accesses. By using biological traits, they offer a level of security hard to replicate.
  • Password and Passcode Locks: Users can set alphanumeric passwords or numeric passcodes, further securing their device from unauthorized access.

App Store Vigilance

  • App Review Process: Before appearing on the App Store, each app undergoes a rigorous review process to ensure it meets Apple’s standards for quality and security.
  • Malware Scanning: Regular scans help keep the App Store free from malicious software. If any app raises concerns, Apple can remove it swiftly to protect users.

Privacy Measures

  • Minimal Data Collection: Apple is known for its privacy-first approach. They collect only the necessary data, often keeping it on the device rather than their servers.
  • Randomized Device Identifiers: Instead of using static identifiers, which can be used for prolonged tracking, iOS often uses randomized identifiers for processes like Wi-Fi. This reduces the ability to persistently track a device.

Regular Updates

  • Frequent iOS Updates: Apple consistently releases software updates, patching any identified security vulnerabilities. Users are encouraged to keep their devices updated for optimal security.

Find My iPhone

  • This feature allows users to locate lost devices, remotely lock them, display a message, or erase their data. It’s a crucial tool for safeguarding personal information in case of device theft or loss.

In conclusion, Apple’s iOS is fortified with an array of security features, both hardware and software-based. From the underlying architecture to the visible user features, each element is designed to ensure data integrity, user privacy, and a seamless, secure user experience. With a holistic approach to security, iOS remains a top choice for many concerned about digital safety.

How do we test antivirus software?

What cyber threats can antivirus not protect you from?

While antivirus software is a strong line of defense against many security threats, it’s not an all-inclusive solution. There are certain cyber threats that require a more comprehensive approach, often involving user awareness and vigilance. Here’s a look at some of these threats:


Phishing attacks involve attempts to steal sensitive data like usernames, passwords, and credit card details by disguising as trustworthy entities in electronic communications. While some antivirus software include phishing protection, no tool can catch every single phishing attempt, as it largely depends on user awareness and education.

Online Scams

Online scams come in many forms, from fraud emails promising large sums of money to fake websites posing as genuine ones. While an antivirus may block known fraudulent sites or flag certain emails, it can’t protect you entirely from falling prey to cleverly disguised scams. Awareness and skepticism when dealing with suspicious emails or websites are the best defenses.

Social Engineering

Social engineering is the use of deception to manipulate individuals into revealing confidential information. This can take place via email, phone calls, or even in-person interactions. As it involves human judgment, antivirus software cannot completely safeguard against it. Regular education and training about social engineering tactics are crucial.

Zero-Day Exploits

A zero-day exploit is a cyber attack that occurs on the same day a weakness is discovered in software. As it happens before the vendor has a chance to create a patch, even the best antivirus software can’t defend against it. Frequent software updates and using software from reliable vendors can help minimize the risk of such exploits.
