While iPhones have strong built-in security and often don't need traditional antivirus, extra steps like enabling two-factor authentication (2FA), using strong passcodes, keeping iOS updated, and being cautious with links are crucial, with additional security apps or a VPN recommended for high-risk users (e.g., frequent public Wi-Fi, sideloading apps) to protect against phishing and other threats.
No, iPhones generally do not require antivirus apps to be installed because they have strong built-in security features. Apple's highly controlled ecosystem also makes its products less vulnerable to malware.
The only operating system that you absolutely do not need to install antivirus software on is iPhones. You also don't need antivirus software on iPads and iPad Minis, although a bit of extra protection never hurts. However, Windows, macOS, and Androids still need antivirus software.
Use a device passcode or password and Face ID or Touch ID. For better security, you can set a passcode on your device — or login password on your Mac — to help protect your data. Use Face ID or Touch ID if your device supports it. Keep your software up to date.
iPhones don't have antivirus like computers do, but Apple's built-in protections, like sandboxing, App Store review, and system updates, help block most threats.

Macs have built-in antivirus and security software, but they aren't foolproof. Macs need third-party antivirus for total protection. Read our TotalAV review, a top-rated software and our favorite antivirus for Macs.
On an iPhone, dialing *#21# is a USSD code used to check the status of your unconditional call forwarding, revealing if your calls, SMS, or data are being redirected and to which number, without actually changing settings; it's a simple privacy check to see if someone has secretly set your phone to forward everything, though it doesn't detect advanced spyware. Dialing this code brings up a message from your carrier about your call forwarding status, often showing "Disabled" or a specific number if it's active.
iPhones don't have a built-in virus scanner, but if you're on iOS 16 or later, you can use Apple's Safety Check feature to review permissions and connected devices.
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.
While iPhones are known for their security, they're not impregnable. If you've ever wondered if your iPhone can get hacked, the answer is yes, it can.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
While Apple doesn't have a built-in virus scanner, you can use trusted third-party security apps to check for suspicious activity. The good news is that iPhones come with strong security features. Thanks to iOS's sandboxing, apps are kept separate, making it hard for traditional viruses or malware to spread.
Set a stronger passcode.
Once a thief changes that passcode, he can easily access and change other settings on your phone that effectively bar you from your own data. I highly recommend shifting to a longer, 10-character alphanumeric passcode that's entered via the keyboard rather than the traditional number pad.
When checking your iPhone for viruses, first check for unfamiliar apps. If you see an unfamiliar app you don't remember downloading onto your iPhone, delete it immediately, because it could contain a virus. You can check if the app is an officially sanctioned iOS-compatible app by checking Apple's App Store.
iPhones are vulnerable to hacking despite being more secure than Android devices. Hackers can exploit security loopholes in the iOS operating system or third-party apps to gain unauthorized access to your device, steal personal data, or install malware.

Fun Fact: According to CERT-IN advisories, Samsung, Xiaomi and Vivo rank among the most hacked phone brands in India, mirroring their dominant shipment figures.
What's the hardest phone to hack? Android phones are generally considered less secure than iPhones thanks to Apple's focus on encryption. But both are more susceptible to hackers thanks to their popularity. The more people who use a phone, the more high value a target it presents to hackers.
