In today’s hyper-connected world, smartphones hold more personal information than ever before—banking apps, photos, work files, health records, and more. So it’s only natural to worry: Can iPhones get viruses? And if so, how do you check for viruses on your iPhone?
While iPhones are widely considered secure, they’re not invincible. If your device is behaving oddly, running slower than usual, or showing pop-ups you didn’t expect, you might suspect it’s infected. Fortunately, Apple’s iOS has strong built-in protections that prevent traditional viruses, but there are still threats you should watch out for—like malicious websites, sketchy profiles, or rogue apps.
In this article, we’ll explain what “viruses” on iPhones really mean, how to check if your iPhone has one, signs to look out for, and what to do to fix or prevent it. No jargon—just clear, practical advice.
Can iPhones Really Get Viruses?
Technically, iPhones don’t get viruses the same way PCs or Android devices do. That’s because Apple uses a security model called sandboxing and has strict rules for App Store apps. Every app runs in its own space and can’t access data from other apps or the system directly.
However, while the risk of actual viruses is extremely low on iPhones, there are other types of malware and security threats, such as:
- Phishing attacks (fake websites, scam texts)
- Malicious profiles or configuration files
- Infected apps from unofficial sources
- Tracking links or hidden spyware
- Adware/pop-up attacks via Safari or third-party apps
So yes, your iPhone can misbehave or be compromised, even if the word “virus” isn’t technically accurate.
Common Signs Your iPhone May Be Infected or Compromised
It’s important to recognize the warning signs of a potential infection or security issue. These include:
🔴 Unusual Pop-ups or Ads
If Safari or apps are suddenly flooded with intrusive ads or pop-ups, especially ones telling you to “Download this app to fix your phone,” it could be a sign of adware or a redirect script.
🔴 Battery Draining Faster Than Usual
Malicious background processes or rogue apps can drain battery abnormally.
🔴 Overheating
While it’s normal for your iPhone to heat up during intensive tasks, unexplained heating could suggest unauthorized background activity.
🔴 Data Usage Spikes
Spyware or adware can use your mobile data to transmit information without your knowledge.
🔴 Unknown Apps Installed
If you see apps you don’t remember downloading, be cautious—especially if your device is jailbroken.
🔴 Redirection to Unfamiliar Websites
Being taken to strange websites when opening links or Safari is often a sign of a script-based redirect.
🔴 Unusual Behavior
Apps crashing, screen freezing, or unexpected restarts can also signal a problem—though not always malware.
How to Check for Viruses on iPhone – Step-by-Step
If your iPhone is showing signs of strange behavior, follow these steps to inspect and secure your device.
✅ 1. Check Battery Usage per App
Go to:
Settings > Battery
You’ll see a breakdown of battery usage by app. If you spot an unfamiliar app or high usage from Safari, it could be a sign of something suspicious running in the background.
✅ 2. Review Recently Installed Apps
Go to:
Settings > General > iPhone Storage
This shows all apps on your device. Look for anything you don’t recognize. Tap on any suspicious app to delete it.
✅ 3. Inspect Safari Settings and Clear Data
If you’re getting unwanted pop-ups or being redirected while browsing:
Settings > Safari
Then do the following:
- Tap Clear History and Website Data
- Turn on Block Pop-ups
- Enable Fraudulent Website Warning
This will remove cookies, malicious scripts, and redirect caches.
✅ 4. Check Configuration Profiles
Malicious configuration profiles can change your iPhone’s settings without your knowledge. These are sometimes installed through phishing emails or fake “setup” websites.
Go to:
Settings > General > VPN & Device Management
If you see a profile you don’t recognize, tap on it and choose Remove Profile.
✅ 5. Scan for Software Updates
Apple often fixes security issues through iOS updates.
Settings > General > Software Update
Make sure you’re running the latest version. Updating can patch vulnerabilities and remove bugs that may be exploited.
✅ 6. Restart Your iPhone
Sometimes, simply restarting your device can disrupt unwanted background processes or stop a Safari hijack.
- For iPhones with Face ID: Press and hold the Side button + Volume Up until the slider appears.
- For older models: Hold the Power button.
- Slide to power off, wait 30 seconds, then turn it back on.
✅ 7. Reset Network Settings (If Safari Keeps Misbehaving)
Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings
This removes all saved Wi-Fi and VPN configurations that may have been altered. Be sure to have your Wi-Fi passwords saved somewhere first.
How to Remove Malware or Suspicious Content From iPhone
If you’ve checked all of the above and still suspect your iPhone isn’t acting right, try these additional methods to clean your device.
🔄 Option 1: Delete Suspicious Apps
Go to the Home Screen, long-press the app, and tap Remove App.
Be extra cautious with apps that:
- Ask for unnecessary permissions
- Serve ads outside the app
- Redirect you to strange websites
- Install without your consent (possible on jailbroken devices)
🔁 Option 2: Reset All Settings
This will reset system settings without deleting your personal data.
Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings
This can resolve deep-level misconfigurations affecting performance or security.
🧹 Option 3: Erase All Content and Settings (Factory Reset)
If the issue persists, and you’re comfortable with starting fresh, a factory reset removes everything—including malware.
- Back up your data using iCloud or iTunes
- Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings
- Follow prompts to complete the reset
- Set up as new (avoid restoring from a backup if the issue came from it)
How to Avoid Viruses and Malware on iPhone
Prevention is better than cure. Here are smart habits to keep your iPhone safe from viruses and other threats:
🔒 1. Only Download Apps from the App Store
Avoid third-party app stores or sideloading apps through web links—these are major sources of malware.
🌐 2. Don’t Click on Suspicious Links
Never tap on pop-ups, spam emails, or unknown message links that promise free prizes or system warnings.
📧 3. Watch Out for Phishing Attempts
Double-check email addresses and avoid entering login info unless you’re sure the site is legitimate.
📱 4. Enable Two-Factor Authentication
Use 2FA for your Apple ID and other apps. This adds a second layer of security even if your device is compromised.
🔍 5. Turn On “Find My iPhone” and Location Alerts
This helps you track or remotely wipe your device in case it’s lost or stolen.
⚙️ 6. Keep iOS Updated
Security patches are released regularly. Set your phone to auto-update for peace of mind.

❓ Q: Can my iPhone get a virus from visiting a website?
Technically no, but you can be affected by malicious scripts or phishing attempts. Always avoid shady websites and clear Safari data regularly.
❓ Q: Do I need antivirus software on my iPhone?
No. Apple’s system is designed to be secure without third-party antivirus apps. Most “antivirus” apps on iOS don’t offer true virus scanning.
❓ Q: Does jailbreaking increase my risk?
Absolutely. Jailbreaking removes iOS’s security restrictions, making your phone vulnerable to malware and spyware.
