Your iPhone isn’t just a phone anymore. It’s your digital identity. That’s exactly what makes it a target for all kinds of attacks. In hybrid workplaces, your personal devices have evolved into a corporate endpoint. With this shift comes the responsibility to secure it. Usually, iOS is built with strong security, but no device is immune to attacks. If your iPhone has begun to slow down, display advertisements unnecessarily, or behave differently, it may have been infected with malware. And knowing how to remove malware from your iPhone is a necessity.
Malware is short for malicious software. It refers to any software designed to harm a device, steal information, or get unauthorized access to personal data. In iPhones, malware is usually introduced from phishing links, jailbreaking or downloads outside of the App Store. The common types of malware in iPhones are,
Malware usually affects the device’s performance and usability. The common indicators are,
Spyware, sometimes called stalkerware, is a special category of malware worth calling out separately.
Unlike adware or trojans, it’s built to stay hidden. It quietly tracks calls, messages, location, and even photos, often installed by someone with prior physical access to your device.
Signs of stalkerware can look subtler than typical malware. Watch for,
Your iPhone showing unusually high background data usage.
The screen briefly lighting up on its own.
Unfamiliar profiles under Settings > General > VPN & Device Management.
Someone seeming to know details about your location or conversations they shouldn’t.
Because stalkerware is designed for surveillance rather than disruption, standard performance issues like lag or overheating may not always appear.
If you suspect stalkerware, prioritize checking configuration profiles and installed apps over waiting for obvious performance symptoms.
In workplace contexts, this is also why unmanaged personal devices connecting to corporate resources pose a bigger risk. A device compromised for surveillance can leak business data just as easily as personal data, reinforcing the need for visibility tools like Hexnode UEM across the fleet.
If you see the above signs, then it is essential to take immediate action. While system-wide antivirus scans are not applicable in iPhones, the remediation relies on manual removal steps like cleaning browser data, uninstalling suspicious apps or configuration profiles, applying software update, or, in extreme cases, performing a factory reset.
A simple restart can terminate any temporary malware in the device.
To restart,
You can also turn off the device by going to Settings > General > Shut Down. This will bring the Slide to Power Off slider.
Malware often comes from infected web data or cache.
To clear Safari data,
Clearing all the cookies and cache is important for removing the trace of malware.
Malware often hides in plain sight by quietly accessing your camera, microphone, or location.
A quick permissions audit can reveal apps that shouldn’t have that level of access.
To review app permissions,
Also check Settings > Safari and make sure Block Pop-ups and Fraudulent Website Warning are both turned on.
These settings stop malicious sites from tricking you into installing malware in the first place.
If an app requests permissions that don’t match its purpose, for example, a calculator app asking for microphone access, treat it as a red flag and remove it immediately.
If your iPhone started to behave oddly after installing an app, then it may be the cause of the attack. Scroll through the apps and find the app which started the issue.
To uninstall it,
Likewise, if the system settings are changed or unknown VPNs are added, then malicious profiles have been configured.
To remove it,
Security updates can fix malware in the device. So, regularly check for patches and keep the device updated.
To update,
Rapid Security Responses allows your iPhone to get urgent security fixes between full iOS updates. These micro-updates protect your device from attacks faster than standard updates.
To enable this,
Stolen Device Protection prevents unauthorized users from changing your security settings or using passwords.
To enable,
If the malware or malicious configuration profile issue persists, a full erase removes everything and restores factory settings.
To perform an erase and restore,
Make sure you restore the backup which was selected is infection free. Select the backup which was done before the malware attack if available.
Malware running in the background usually leaves a footprint in your battery and data statistics, even when it’s otherwise well-hidden.
Make it a habit to check,
Settings > Battery to spot apps consuming unusually high power relative to how often you use them.
Settings > Cellular to see which apps are using large amounts of data in the background.
A sudden spike from an app you barely open is often the clearest early warning sign of infection, sometimes appearing before any pop-ups or slowdowns are noticeable.
Reviewing these two screens weekly takes less than a minute and can catch malicious activity long before it escalates into data theft or ransomware.
Explore how Hexnode helps in iPhone management with deployment, security, and compliance capabilities for enterprises.
Download datasheetFor organizations managing multiple iOS devices, Hexnode UEM offers remote controls to detect, remove, and prevent malware threats at a large scale. Hexnode acts as a central hub allowing IT admins to remotely manage the device and introduce policies to minimize security risks.
With Hexnode we can,
While iPhones benefit from Apple’s strong security architecture, they are not immune to unwanted software or threats. Understanding the signs of attack, taking immediate action to remove it, and establishing preventive measures with the help of tools like Hexnode or individually, can maintain the performance and safety of the device. But constant supervision and responsible usage remain the best defense.

Yes, an infected personal device connected to corporate email, Wi-Fi, or cloud accounts can act as an entry point into business systems. This risk grows in hybrid work setups where personal and corporate data overlap on the same device. Managed containers and network access controls help limit this exposure.
Stalkerware is designed to stay hidden rather than disrupt performance, so it often shows fewer obvious symptoms like lag or crashes. Removal focuses on checking configuration profiles and installed apps rather than waiting for performance issues to appear. In some cases, a full erase is the most reliable way to ensure it’s gone.
Yes, a UEM solution allows IT admins to remotely detect suspicious apps, remove configuration profiles, and push OS updates without needing the device in hand. This is especially useful for distributed or remote workforces. Actions like forced wipes or app removal can be triggered directly from a central console.
Apple’s ecosystem significantly reduces malware risk through sandboxing and App Store review processes, but it does not make devices immune. Threats like phishing links, malicious configuration profiles, and jailbreaking can still bypass these protections. Additional monitoring is recommended for devices handling sensitive or corporate data.
Start by checking recently installed apps and comparing when the symptoms began. If the source remains unclear, review app permissions and background data usage for unusual activity. If the issue persists, performing a full erase and reinstalling only trusted apps is the safest option.
