iPhones are widely considered to be quite secure against malware and viruses, thanks to Apple’s closed iOS operating system and App Store review process. However, iPhones are not completely immune to malware. Here are some quick answers about iPhone security against viruses:
Are iPhones prone to viruses?
No, iPhones are not prone to traditional computer viruses that infect Windows PCs. The iOS operating system is designed to be very secure against malware installation and spread. Apps can only be installed through the official App Store, which screens apps for malware.
Can you get a virus on an iPhone?
It’s extremely rare, but not impossible. A few isolated malware strains like Pegasus have infected a small number of iPhones, mainly targeting high-profile individuals. But there are no widespread iPhone virus outbreaks like on other platforms.
Do iPhones need antivirus software?
No. There are no known virus threats in the wild that require an antivirus app on iPhone. Apple’s built-in security makes antivirus software unnecessary for most users.
Why are iPhones safer from viruses?
There are several key reasons why iPhones are much more secure than other devices:
- Closed operating system – Apple controls all iOS updates and apps.
- App Store screening – All apps are reviewed for malware before release.
- Sandboxing – Apps are isolated from each other and can’t access system files.
- Encryption – iOS uses advanced encryption for data security.
- Timely updates – Apple is quick to deploy any security patches.
Can you remove a virus from an iPhone?
If an iPhone did somehow get infected, you can remove any malware by:
- Deleting suspicious apps.
- Running antivirus software.
- Backing up data and performing a factory reset.
- Updating to the latest iOS version.
How can I be safe from iPhone viruses?
Here are some tips to improve your iPhone security against any potential malware threats:
- Only install apps from the official App Store.

- Watch out for suspicious links and attachments.
- Use strong passcodes and Touch ID/Face ID.
- Install iOS updates right away.
- Use built-in protections like Find My iPhone.
Can you get a virus from Safari on iPhone?
It’s unlikely, but possible in theory. Visiting a compromised website in Safari could potentially lead to a drive-by download of malware onto an iPhone. But the chances of this happening are extremely low due to iOS security protections.
Should I use antivirus software on iPhone?
Antivirus apps will not provide significant protection beyond what is already built into iOS. Security experts agree that antivirus software is unnecessary on iPhones for most users. The only exceptions are high-risk users like journalists and activists.
Do iPhones have built-in virus protection?
Yes. While there is no specific anti-virus software, iOS has extremely robust built-in protections including:
- App Store review process
- Sandboxing of apps
- Encryption
- System integrity protection
- Malware scanning and blocking
- Rapid security updates
These protections make it extremely difficult for viruses to infect an iPhone.
Conclusion
In summary, while it’s theoretically possible for an iPhone to become infected, it is highly unlikely. Apple has designed iOS with strong security measures to block malware installation and spread. iPhones do not require separate antivirus apps. With basic precautions like avoiding suspicious links and apps, users can feel confident that iPhones are very well protected against viruses and malware.
Frequently Asked Questions
Can I get a virus from visiting a website on my iPhone?
It’s extremely unlikely. iOS security makes it very difficult for malicious websites to infect your iPhone without you explicitly installing software. As long as you don’t download files or apps from dubious websites, your risk of infection from a website alone is negligible.
Should I use a VPN on my iPhone for virus protection?
Using a VPN provides some privacy and security benefits, but is unnecessary solely for blocking viruses. iOS already encrypts your web traffic and blocks malware installation. A VPN gives no significant advantage against viruses beyond what’s already built into your iPhone.
Can iPhone viruses steal my personal data?
Extremely unlikely, thanks to iPhone encryption and sandboxing. Any malware would only have access to data within its own app “sandbox”, not your personal data from other apps or system files. Remote data theft is very difficult due to iPhone encryption.
Will resetting my iPhone get rid of a virus?
Yes, resetting your iPhone to factory default settings will wipe out any malware present. This is a last resort if you somehow get infected. Make sure to backup your iPhone data first, then erase all content and settings.
Can I get a virus from chargers or cables?
No. iOS security prevents malicious chargers or cables from installing any malware. At worst, dubious accessories could damage the battery or hardware, but cannot infect your device with viruses.
Preventing Virus Infections on iPhone
Here are some key tips to keep your iPhone malware-free:
Install apps only from the App Store
The official iOS App Store offers the best protection against malware. Apple thoroughly vets all apps before approving them for sale. Downloading apps from anywhere else bypasses this security review, risking malware infection.
Think before granting app permissions
When installing new apps, be cautious when granting access to data like contacts, photos and location. Only allow permissions genuinely needed for app features. Overly broad access raises your risk if the app is compromised in future.
Keep your iPhone up to date
Make sure to promptly install major iOS updates and security patches. These often include fixes for vulnerabilities that could be exploited by malware if left unpatched.
Don’t jailbreak your iPhone
Jailbreaking removes many of Apple’s built-in protections, allowing unscreened app installs. This hugely increases the risk of malware. Avoid jailbreaking unless you fully understand and accept the security trade-offs.
Be cautious of public Wi-Fi hotspots
Free public Wi-Fi carries inherent security risks of man-in-the-middle attacks to steal passwords or inject malware. Use VPN if connecting through public hotspots and avoid accessing sensitive data.
Watch what you click in emails and messages
Phishing scams try and trick you into installing malware by socially engineering you to click infected links. Be wary of unknown links even if seemingly from contacts.
Dealing with Malware on iPhone
If your iPhone does get infected, here are the steps to remove malware:
Delete any suspicious apps
Check through your apps for anything dubious that could be the source of infection. Delete anything unfamiliar or unnecessary. This may remove the malware.
Run reputable antivirus software
Try scanning your device with a reputable AV app like Malwarebytes to identify and quarantine infections. This can often detect and remove malware.
Back up data and reset iPhone
If other methods fail, erase your iPhone and restore from a clean backup. This wipes any malware and gives you a fresh start. Don’t restore corrupted data which could reinfect your device.
Update to latest iOS version
Installing the newest iOS firmware can patch vulnerabilities used to infect your device. Do this after resetting your iPhone to address the root cause.
Symptoms of iPhone Malware Infection
Here are some signs you may have malware on your iPhone:
| Slow performance | Malware strains system resources, slowing normal use. |
| Diminished battery life | Constant background activity by malware drains your battery faster. |
| Data usage spikes | Some malware communicates out to command servers, using mobile data. |
| Unknown apps | Scan for any apps you don’t remember installing yourself. |
| Pop-up ads | Adware pushes intrusive pop-up ads outside of browsers. |
| Heating up | Resource-intensive malware can cause iPhone to run hotter. |
However, these symptoms can also be caused by non-malicious issues like buggy apps. Diagnostic scans using antivirus software are needed to confirm malware infections.
Security Risks of Jailbroken iPhones
Jailbreaking bypasses many of Apple’s security protections, increasing malware risk:
- No app screening – Software from any source can be installed.
- Unrestricted filesystem access – Malware can meddle with system files.
- No sandbox for apps – Malware can access data from other apps.
- Disabled Apple protections – Key defenses are removed.
- Riskier app permissions – Apps can demand excessive access rights.
- Susceptible to phishing – More convincing phishing lures can be installed.
These factors make malware attacks much easier to succeed. Users should avoid jailbreaking unless they are technical experts able to manage the increased risks.
Examples of iOS Malware
Here are some real-world examples of iOS malware:
Pegasus
This notorious spyware from NSO Group was used to target journalists and activists. It exploited an iOS zero-day vulnerability to install itself without user interaction.
