No — because of “sandboxing” an antivirus app can’t scan your iOS device as apps are unable to interact with other apps in that way. Instead, the best antivirus apps for iOS protect your device and data from external threats like phishing scams and loss or theft.
The scans that antivirus apps perform aren’t looking for viruses but for vulnerabilities and security gaps. For example, the antivirus can detect if your operating system has an available update and prompts you to download it. Your antivirus can also scan your network connection for any security issues and recommend steps you can take to rectify the issue.
