How to check for and clean viruses on iPhone 16 Pro Max?

Unless you have given your phone to someone else for a few hours and also provided them with your Apple Account and Password, there is no virus on your phone.

No need. Don't worry about it.

Assuming you have done anything against Apple’s standard iPhone processsws, your iPhone cannot receive a virus. You must be diligent in the apps you use, sites you visit, etc.
