If you’re an Apple iPhone owner, there’s a good chance that one of the reasons you love your smartphone is that Apple devices tend to have fewer vulnerabilities to viruses.

Because of their shared operating system with other Apple devices, iOS devices enjoy the same security measures, which keep them protected from malware and viruses in the same way that Apple computers are. This is great, right? But it’s also important to remember that nothing digital or internet-related is ever foolproof. While it’s rare, even iOS can be affected by malicious software.

The good news is that protecting your iPhone from viruses and hackers isn’t hard. In this article, you will learn the signs that your iPhone could be infected with a virus, the ever-evolving cyber threat landscape, and the steps you can take to keep your device protected.

Can iPhones get viruses?

Apple’s iOS for iPhones is built on a foundation of hardware security capabilities built into silicon. Another pillar of Apple security is the secure boot, which protects the system from malware attacks while booting, then builds a chain of trust through software updates, and protection of the entire system such as CPU, memory, disk, software programs, and stored data. Each step is engineered to ensure that the next is functioning properly before proceeding.

Apple devices are designed to work exclusively with other Apple-approved devices – from iOS to iPadOS, macOS, tvOS, watchOS, and visionOS, etc., with encryption technology that makes your iPhone security almost impervious to malicious apps.

Additionally, features like the Secure Enclave protect your most sensitive data, such as Face ID, Touch ID, and passcode information, in a separate, fortified processor. Apple promptly issues OS patches to fix vulnerabilities as soon as they are found.

Sandboxing apps before the download

Enforcing strict code-signing for all apps in the App Store is one way Apple ensures that every app is verified and approved before you download it.

When you do download an app from the App Store, iOS activates a technique called sandboxing, which isolates each app to prevent it from accessing data from other apps or the core operating system.

What then do security apps on the App Store do? They provide crucial protection in other ways, such as offering a virtual private network (VPN) to encrypt your connection, blocking phishing websites, and monitoring for identity theft.

While Apple’s iOS system is quite formidable, it’s still possible for it to be infected with a virus. This usually happens with jailbreaking, the process where the device owners unlock a closed device to gain full access to its operating system and administrator account. When you jailbreak an iPhone, you open the iOS to a wide range of apps, features, and themes, none of which are approved by Apple. In the same vein, you won’t benefit from the virus protection of the closed system, exposing your iPhone to adware, scams, and other internet security issues. Further, threats such as phishing scams, unsecure Wi-Fi networks, and malicious configuration profiles can bypass these protections.

Evolving threat landscape

To increase their chances of invading your iPhone, cybercriminals have developed modern ways to trick you into compromising your own mobile security. In recent times, we have seen a surge in mobile-first phishing attacks, with reports indicating that over 80% of phishing sites target mobile devices. These aren’t just emails; they come through smishing, social media, and QR codes. Advanced threats like zero-day exploits and commercial spyware like Pegasus can infect devices without any user interaction at all.

Another growing risk is the use of malicious configuration profiles, which can be installed via a deceptive link to reroute your internet traffic or spy on your activity. This evolving landscape underscores iOS’s need for more protection, not only against viruses, but to provide a layered defense.

The need for layered security on iPhone devices

For users who stick to the App Store and maintain good security habits, these built-in protections are quite powerful. However, the threat landscape has evolved. Today’s biggest risks are often sophisticated user-focused threats that trick you into revealing passwords, malicious configuration profiles that spy on your data, and even rare but potent zero-click exploits.

While Apple’s defenses are strong, they can’t stop you from clicking a malicious link or connecting to a compromised Wi-Fi network. This is where security suites add critical layers of protection, offering a secure virtual private network, identity monitoring, and safe browsing to guard against the modern threats that target you, not just your device.

Consider an iPhone antivirus app

While a healthy, up-to-date iPhone is secure by design, certain behaviors significantly increase your risk profile, making a security app a smart decision. If you have a jailbroken phone or have sideloaded enterprise profiles with apps outside the App Store, you’ve bypassed Apple’s core protections. You should also strongly consider one if you frequently use public Wi-Fi at airports, cafes, or hotels, as these networks are often unencrypted and ripe for snooping.

Additionally, if your iPhone stores sensitive work data or is used by kids or teenagers who may be less cautious online, an extra layer of defense is crucial. In these scenarios, a comprehensive security app adds protections where native tools can’t, such as encrypting your connection, blocking phishing websites, and monitoring your identity if your personal information is found in a data breach.

Potential threats to your iPhone

Here are a few potential threats that a jailbroken iPhone might face:

  • Phishing: Phishing happens when a cybercriminal sends a fraudulent message aimed at directing you to a fake website that convinces you to log-in and reveal personal or financial information. Unfortunately, malicious websites don’t come with a warning. If your iPhone is successfully phished, private data on the iCloud and your device can be compromised.
  • Ransomware: Unsecured Wi-Fi networks can expose connected devices to ransomware, a type of malware that threatens to permanently block your access to your device unless you pay money. Some ransomware will even threaten to publicly publish your private information if you don’t pay a ransom.
  • Malware: Malware is any software program intended to gain unauthorized access to a computer system or device. Malware can disrupt or disable a device, network, or specific user. It can also actively leak private information and create privacy concerns.

5 signs your iPhone has a virus

If you used the Wi-Fi at a coffee shop last week, don’t jump and download the first best antivirus for Apple that you see. First, determine if your iPhone indeed is infected with a virus. Here are a few telltale signs:

  • Overheating: Being out in the extreme sun or having an old battery can be culprits for overheating. But if you repeatedly see that red thermometer on your screen, your iPhone is warning you that it’s infected with malicious software.
  • Unexplained data usage: If you don’t have an unlimited phone plan, you probably keep a pretty close eye on data usage. But if you see significant jumps in usage that don’t match your activity, this is a sign your iPhone may have a virus.
  • Pop-ups: Sometimes, there’s no escaping those pesky pop-up ads when you’re online. But being bombarded with pop-ups could indicate that your Apple device is harboring a virus.
  • Suspicious apps: Make a habit of scrolling through your list of apps from time to time. If you see anything that you don’t remember downloading yourself or that didn’t come with your iPhone, this could be a red flag.
  • Quick battery drainage: If your iPhone is older or has many big apps, your battery will typically drain faster. But it could also mean that an unwanted and unseen program is running in the background.

Step-by-step: Check and remove a virus from your iPhone

  1. Review recently installed apps: Look through your apps for anything you don’t recognize. Malicious apps can sometimes be installed without your direct knowledge, especially on jailbroken devices.
  2. Check battery usage and data analytics: Go to Settings > Battery to see if any unknown app is consuming an unusual amount of power. Similarly, check your cellular data usage for unexpected spikes.
  3. Inspect configuration profiles: Navigate to Settings > General > VPN & Device Management. Look for any profiles you did not install yourself, as these can be used to control your device.
  4. Check analytics & improvements data: Frequent app crashes or unusual entries could indicate a problem. You can review analytics data under Settings > Privacy & Security > Analytics & Improvements.
  5. Update iOS: Make sure your device is running the latest version of iOS to benefit from the most recent security fixes.
  6. Monitor web history & pop-ups: Frequent pop-ups or strange redirects in Safari can be a sign of adware or other malware.
  7. Restore if jailbroken: If your phone is jailbroken and you suspect a virus, the most effective solution is to restore it to factory settings. For continuous peace of mind, use a reputable mobile security tool for ongoing threat detection and monitoring.

Removing a virus on iPhone

If checking did not turn up any virus on your iPhone, then there’s nothing to worry about. If, however, you determine for sure that a virus is lurking in your device, here are steps you can follow to remove it:

  1. Restart your iPhone: A simple reboot can sometimes resolve issues caused by minor software glitches or malware.
  2. Delete suspicious apps & profiles: If you notice an app you don’t remember installing, delete it immediately. Also, check for any unknown configuration profiles under Settings > General > VPN & Device Management and remove them.
  3. Clear Safari history and data: Go to Settings > Safari, and tap Clear History and Website Data. This can remove malicious code stored in your browser’s cache.
  4. Update to the latest iOS version: Apple regularly releases security patches. Ensure your device is up-to-date by going to Settings > General > Software Update.
  5. Restore from a previous backup: If the problem persists, you can restore your iPhone from an iCloud or computer backup made before the issues started. As a last resort, perform a factory reset, but be aware this will erase all data.
  6. Enable ongoing protection: Install a reputable security app to detect and block threats like phishing links and unsecure networks in the future. If you are still unable to resolve the issue, it may be time to contact Apple Support for professional assistance.

Proactively protect your iPhone

The first and best way to protect your iPhone from cybersecurity concerns is to avoid jailbreaking it in the first place. While the device might limit the apps and themes you can install, its built-in security features really can’t be beaten.

Here are other ways you can keep your iPhone safe from malware and viruses:

  • Keep software updated. Each new version of Apple iOS has patches for security holes discovered by Apple’s internal hackers. Be sure to keep your iPhone software updated to enjoy its latest security features. You can even set up automatic software updates to make things easier.
  • Set up USB restricted mode. Protect your data from juice jacking, where someone steals your data through your phone’s USB port while it’s plugged into a public charger. Head to Settings > Face ID and Passcode. Enter your passcode and toggle USB Accessories.
  • Use a password manager. A password manager can lend additional layers of security to Apple’s already highly encrypted operating system. Some services help you create strong passwords and use biometric security features like fingerprint recognition.
  • Enable Touch ID. This may seem like an old-school feature compared to facial recognition. But enabling Touch ID can reduce the risk of unauthorized access to your iPhone since it requires your physical presence to open it.
  • Use a VPN. If you use public Wi-Fi a lot, you risk exposing your personal information. A virtual private network uses encryption to keep your online data protected no matter where you are.
  • Consider antivirus software. Antivirus software can handle many potential vulnerabilities by looking out for online threats like hackers, offering real-time threat protection across multiple devices and can help keep your iPhone free of data breaches.

Choose the best antivirus: Key features to consider

The best security app for an iPhone goes beyond traditional virus scanning and provides holistic protection against modern threats. As you evaluate your options, use this checklist to ensure you’re getting comprehensive security:

  • Scope of protection: Look for an all-in-one solution that offers key features such as a secure VPN for public Wi-Fi, identity monitoring for data breaches, and safe browsing capabilities to block phishing links, malicious websites, and scam pages.
  • Privacy policy transparency: A trustworthy provider will be upfront about the data it collects and how it’s used. Read the privacy policy to ensure your data is being protected, not sold.
  • App store ratings and reviews: Check recent user feedback in the App Store. Consistent high ratings and positive reviews are a good indicator of a reliable and effective app.
  • Performance impact: A quality security app should run efficiently in the background without noticeably draining your battery or slowing down your device.
  • Support and pricing: Look for a plan that offers good value, including coverage for multiple devices and access to customer support if you need help.
  • Cross-device Coverage: A single subscription should protect not only your iPhone but also your Mac, PC, and Android devices, providing consistent security across your entire digital life.

Built to meet every one of these criteria, our solution delivers a powerful and trusted security solution that protects your identity, privacy, and devices in a single, easy-to-use application.

Same protection, different device

Like your iPhone, Apple’s iPad tablets run on a similar closed-system architecture called iPadOS, which benefits from the same robust security measures. However, iPads are not entirely immune to threats, especially if you connect to unsecured public Wi-Fi, install unvetted third-party apps, or fail to update the operating system.

Since your digital life often spans multiple devices, using a comprehensive solution provides consistent security across both your iPhone and iPad. A single security subscription can cover multiple devices without extra cost. While the core security features remain the same, you might notice a more expansive layout that takes advantage of the iPad’s larger screen, such as a split-view dashboard. Setting it up on your tablet is simple:

  1. Download the McAfee Security app from the App Store onto your iPad.
  2. Sign into the app with the same account you use on your iPhone.
  3. Follow the on-screen prompts to enable key features like Web Protection and the Secure VPN.
  4. Confirm your device is protected from the main dashboard.

Meanwhile, macOS includes powerful built-in security layers like Gatekeeper, which blocks unverified apps, and XProtect, which scans for known malware. However, the expanding threat landscape deems these insufficient on their own. Hackers are continuously developing malware that rely on social engineering to trick you into bypassing Apple’s protections, then steal your passwords, financial data, and personal files.

For comprehensive security, having a multi-device solution provides consistent, powerful protection for both your Mac and iPhone, guarding your entire digital ecosystem against the latest threats.

Maximum performance, minimum impact

In the past, some antivirus programs were known for being resource-heavy, slowing down a device’s performance. However, modern security solutions are now designed to be lightweight and efficient.

For instance, sandboxing capabilities only focus on targeted, low-impact functions, rather than performing system-wide scans that tax the CPU. A VPN only uses resources when it’s active, and safe browsing features check URLs against a cloud-based list with minimal overhead.

Free vs. premium antivirus apps

When considering security for your iPhone, it’s important to weigh the differences between free and paid solutions. Free antivirus apps can provide a basic level of protection, often including features like a Wi-Fi scanner. However, they may come with trade-offs such as intrusive advertising, limited functionality, and questionable data collection practices.

Premium suites, on the other hand, offer a much deeper level of protection, offering more advanced features such as unlimited secure VPN, comprehensive identity theft coverage, restoration support, and robust customer support. Paid plans also typically include multi-device licenses, allowing you to secure your iPhone, iPad, and Mac under a single, cost-effective subscription, delivering far greater value.

Security tips for daily iPhone use

  • Enable automatic updates: Go to Settings > General > Software Update and turn on ‘Automatic Updates’ to ensure you always have Apple’s latest security patches.
  • Use a strong passcode and Face ID/Touch ID: A complex alphanumeric passcode is harder to crack. Always enable biometric security for a fast and secure way to unlock your device.
  • Review app permissions: Regularly check which apps have access to your camera, microphone, location, and contacts. Go to Settings > Privacy & Security to revoke any permissions that an app doesn’t need.
  • Avoid sideloading apps: Only download apps from the official Apple App Store. Installing apps from other sources or jailbreaking your phone bypasses critical security checks.
  • Audit configuration profiles: Navigate to Settings > General > VPN & Device Management. If you see any profiles you don’t recognize, delete them immediately as they can be used maliciously.
  • Turn on Find My: This essential feature helps you locate, lock, or remotely erase your iPhone if it is lost or stolen, protecting your data from falling into the wrong hands.
  • Back up your data: Regularly back up your iPhone to iCloud or a computer. If your device is ever compromised, you can restore your personal data to a new or clean device.
  • Use McAfee secure VPN on public Wi-Fi: Public networks are hotspots for snoops. A VPN encrypts your connection, making your online activity and personal data invisible to others.
  • Monitor your identity: Use Identity Monitoring to get alerts if your email address or other personal information is exposed in a data breach, helping you act fast to secure your accounts.
