I got a message that my IPhone is detected with 2 viruses

There are no viruses that can affect an iPhone, those types of messages come from website ads and are always scams.

Ignore them. There is no virus on your iPhone.

Ignore the message. It is a spam.

The other people posting on here are right. That has got to be spam and a scam. Don't worry about it and do not answer back if it asks you to do something. Take care
