Apple's operating system (iOS) provides iPhones and other Apple devices with security features that make it extremely difficult for malware to infiltrate. However, if the phone has been tampered with, it may be worth taking additional security measures to protect your devices, such as installing anti-virus software. iPhones are natively secure and it's very difficult to get viruses, malware, ransomware, etc. Anyway, you can't get any anti-virus protection for iPhones because apps don't have permission to monitor processes and downloads on the iPhone.
I've never seen a virus or anything like that on an iPhone, the security built into iOS is really good and it would be very difficult to get any type of virus. As with iPhones, viruses are not a major threat to iPads. However, no device or operating system is completely secure by default. As with any other device, there are other security threats besides viruses on the iPad.
Phishing, altered advertising, insecure Wi-Fi networks, and data breaches also pose a threat to the security of iPad users. The good news is that most of us will never run any risk of getting viruses on our iPhones. They're mostly safe, and if you're careful, you don't have to worry. You don't need an antivirus for your iPhone or iPad.
In fact, any anti-virus application you see advertised for iPhones isn't even anti-virus software. They're just security programs that can't really protect you from malware. While they are generally safe if Apple's operating parameters are respected, one of the main ways in which iPhones have become more vulnerable to viruses is through the practice of “jailbreaking” or buying a jailbroken iPhone. It's quite surprising that the iPhone doesn't need any antivirus, but you still have to do your part to protect yourself and your iPhone.
That's why there isn't a single example we've seen of an iPhone security application that prevents malware from infecting an iPhone. And while research suggests that iPhones are less vulnerable to cyberattacks than Android phones in general (in part because Apple's ecosystem is largely closed to its developers), that doesn't mean your iPhone is 100% safe from the infiltration of a cybersecurity threat. Fortunately for Apple fans, iPhone viruses are extremely rare, but not unknown; in recent years, some iPhone users have been able to recall the effects of Pegasus (a form of spyware that spreads through text messages) or AdThief (a form of adware that published unwanted advertisements from a pirated network). The iPhone also has other security features, so no one will be able to access it physically or digitally.
iPhones have the built-in Find My iPhone feature that works through iCloud and allows you to remotely locate, lock or erase a lost or stolen iPhone.
