Malicious software, also called malware, refers to any program or code engineered to harm or exploit computer systems, networks and devices. It affects your phone’s functionality, especially if you jailbreak your device—that is, opening your iOS to additional features, apps, and themes.
The risks associated with a malware infection can range from poor device performance to stolen data. Cybercriminals typically use it to extract data—from financial data and healthcare records to emails and passwords—that they can leverage over victims for financial gain.
Thanks to their closed ecosystem, built-in security features, and strict policies on third-party apps, Apple devices tend to be generally resilient against malware infections. It’s important to note, however, that they’re not completely without vulnerabilities.
Read on to learn how you can detect malware on your iPhone and how to remove these infections so you can get back to enjoying your digital activities.
While traditional self-replicating viruses are rare on iPhones, malware is a genuine threat for Apple devices. Malware typically enters through links in deceptive texts or emails or through downloaded, unvetted apps rather than system-wide infection. These are some types of malware that could infect your iPhone:
To keep you safe against malware and other threats, Apple engineers the iPhone with multiple security layers, including:
Together, these features create a highly secure environment for iPhones. However, this robust shield does not eliminate all risks, as threats can still bypass these defenses through phishing scams or by tricking a user into installing a malicious configuration profile.
If your iPhone is exhibiting these odd activities listed below, a manual scan is your first point of order. These quick actions are free to do as they are already integrated into your device.
The disadvantage of doing a manual scan is that it requires effort. In addition, it does not detect sophisticated malware, and only identifies symptoms rather than root causes.
If your iPhone persistently exhibits any of the red flags above despite your quick actions, you may have to investigate using a third-party security app to find the threats that manual checks don’t catch.
Compared with manual or built-in scans, third-party solutions like McAfee Mobile Security offer automated, comprehensive malware scans by detecting a wider range of threats before they enter your digital space. While available at a premium, third-party security suites offer great value as they include full-scale protection that includes a safe browsing feature to protect your digital life and a virtual private network (VPN) for a more secure internet connection.
If the scan confirms the presence of malware on your iPhone, don’t worry. There’s still time to protect yourself and your data. Below is an action plan you can follow to remove malware from your device.
In many cases, hackers exploit outdated versions of iOS to launch malware attacks. If you don’t have the latest version of your operating system, it’s a good idea to update your iOS immediately to close this potential vulnerability. To do this, go to Settings > General > Software Update and follow the instructions to update your iPhone.
It might sound simple, but restarting your device can fix certain issues. The system will restart on its own when updating the iOS. If you already have the latest version, restart your iPhone now.
If updating the iOS and restarting your device didn’t fix the issue, try clearing your phone’s browsing history and data. If you’re using Safari, go to Settings > Clear History and Website Data > Clear History and Data. Keep in mind that the process is similar for Google Chrome and most other popular web browsers.
Malicious software, such as spyware and ransomware, often end up on phones by masquerading as legitimate apps. To err on the side of caution, delete any apps that you don’t remember downloading or installing.
The option to restore to a previous backup is one of the most valuable features found on the iPhone and iPad. This allows you to restore your device to an iCloud backup version that was made before the malware infection. Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings > Restore from iCloud Backup.
A factory reset should be your last resort when other removal methods have failed, as it is a complete data wipe. That means it will erase all content and settings, including any malicious apps, profiles, or files, returning the software to its original, out-of-the-box state. That’s why it’s crucial to back up your essential data such as photos and contacts first. Also, remember to restore to an iCloud backup version *before* the malware infection to avoid reintroducing the infection. For the highest level of security, set the iPhone up as new and manually redownload trusted apps from the App Store. When you are ready to reset, go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings > Set Up as New iPhone.
Spyware is designed to be sneaky, but it leaves subtle traces. Pay attention to your iPhone’s behavior, such as the camera or microphone unexpectedly activating as indicated by a green or orange dot in the status bar, sudden battery drain, or your device overheating for no reason. Another major red flag is a spike in data usage when you aren’t actively using your phone.
For a deeper look, do this 5-minute check to see which apps have accessed your data, camera, and microphone. Look for any activity that seems suspicious or that you don’t recall authorizing.
If you suspect your iPhone has been compromised, it’s important to act quickly. Here’s a step-by-step process to remove it, restore your privacy, and prevent future threats.
A common tactic used by scammers is the fake virus pop-up. These alarming messages appear while you are browsing, often using logos from Apple or other trusted companies, and claim your iPhone is infected. Their goal is to create panic, urging you to click a link, download a fake app, or call a fraudulent support number. Never interact with these pop-ups. Here’s a quick response plan when dealing with fake virus pop-up ads:
Never enter personal information, passwords, or payment details on a page that appears from a pop-up ad.
The best way to protect your iOS device is to avoid malware in the first place. Follow these security measures to safeguard your device:
Can my iPhone get a virus from opening an email?
Simply opening an email is very unlikely to infect your iPhone. However, clicking a malicious link or downloading an attachment from a phishing email can lead you to a harmful website or trick you into compromising your information. It’s the action you take, not opening the email itself, that creates the risk.
How do I know if a virus warning is real or fake?
Any pop-up in your browser that claims your iPhone has a virus is fake. Apple does not send notifications like this. These are scare tactics designed to trick you into clicking a link or calling a fake support number. The safest response is to close the browser tab and clear your browsing data.
Does my iPhone really need antivirus software?
It’s a misconception that iPhones are immune to all viruses. While Apple’s built-in security provides a strong defense, it doesn’t offer complete protection. Cybercriminals are increasingly using phishing, smishing, AI voice cloning, deepfake videos and other social engineering methods to target iPhone users. A comprehensive security app provides layered protection beyond the iOS integrated security. Think of it as adding a professional security guard to already-strong walls.
What is the best way to check my iPhone for a virus or malware for free?
You can perform manual checks for free by looking for suspicious apps, checking for unusual battery drain and data usage, and reviewing your App Privacy Report. While helpful for spotting obvious issues, these manual checks aren’t foolproof. A dedicated security app offers a more reliable and thorough analysis.
Can an iPhone get malware without jailbreaking it?
Yes. While jailbreaking significantly increases the risk, malware can still infect a non-jailbroken iPhone. This typically happens through sophisticated phishing attacks, installing malicious configuration profiles from untrusted sources, or, in very rare cases, by exploiting an unknown vulnerability in iOS, known as a “zero-day” attack.
Is an iPhone malware scan truly necessary?
Given the value of the personal data on our phones, a regular malware scan provides significant peace of mind. A reputable security app can identify vulnerabilities you might miss, such as outdated software or risky system settings, helping you maintain a strong security posture.
Keeping your iPhone secure from malware is an achievable goal that puts you in control of your digital safety. By combining smart habits with powerful security tools, you can confidently protect your personal information from emerging threats.
