My IPhone 11 says I have the Trojan virus and my stuff keeps freezing and glitching.

It’s an advertisement.

That particular example looks to be a pop-up advertisement, and can be ignored.

The claims made are false.

Your iPhone is fine.

The advertiser here did what pop-up and calendar advertisers do, they lied. They cannot scan your device. (If a website could do that, they’d just upload all your data. So browsers block websites from accessing your data. Which means the websites can’t run the scans for malware. Because a malware scan is intrusive. iPhone and iPad don’t allow local storage scans, either; apps are blocked from and just can’t poke around in the storage. So the authors of the pop-up advertisement lie.)

The other common path for those is arriving via the calendar app and a calendar subscription, and proof of little more than that vendors of some app store apps can fund and can profit from false advertisements and are apps probably best avoided.

Some website offered a “do you want to get notifications?” prompt, and those are what adds the calendar subscription.

Here is how to remove the subscribed calendar, if you should get one of those:

Here? It’s a web web pop-up advertisement. Web pop-ups ~never advertise anything you want. ~Never. They’re best assumed to be scams. The local advertising-related rule of thumb: never install anything you didn’t go looking for. And never from a pop-up.

Three Thoughts:

A. Report This:

If this is a text message, then report this this. Do so with a screenshot. Find out more here: Using the Photos App to Report Scams: - User Tip

B. Use Malwarebytes Mobile Security:

The free version blocks popups. Read the following post to see how to use this software: Blocked numbers - Apple Community

and...



C. Modify your Credentials:

If you suspect activity issues, and interacted with it an any form, then modify the you credentials:

• Modify: your login credentials (Using Both a New eMail and a New Password for each and all sites)
• Associate: a different method of payment to your account
• Enable: Two-Factor Authentication for Apple ID and for all other accounts that have such an applicable option

Kindly post a screen shot of what you’re seeing.

Usual causes of this are a web popup advert, or a subscribed calendar filled with spam, neither of which are a problem with the iPhone or its software.

And if there’s an add-on VPN client app installed, remove that.

Unless you've jailbroken your phone, you don't have a Trojan Virus.

This is more likely a Phishing Scam intended to get you to buy something you don't need. See this link --> Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support

13 viruses? Why not 14 or more?

Note: No virus can run on an unmodified iPhone.

It's a scam. Ignore it.

Also do not support VPN or any apps that uses scare tactics.
