What to do about a fake virus alert or a redirect on your iPhone

HBKL Labs LLC ยท Updated 2026-11-07

A pop-up or full-screen page that says your iPhone has a virus is a scam, not a real warning. Close the tab, do not call the phone number or tap anything on the page, and do not install what it offers. If you typed a password on it, change that password right away.

What to do right now
1. Close the tabApple says pop-ups that claim your device has a security problem or a virus are typically fraudulent ads, and advises closing the window or tab instead of following their links or calling their number.
2. Do not call the numberThe FTC says real security pop-up warnings never ask you to call a phone number, and that legitimate tech companies will not contact you by phone, email or text to say your computer has a problem.
3. Do not install what it offersApple advises installing software only from the App Store or a developer's official website.
4. If you typed a passwordChange it right away, and change any other account that uses the same password (FTC). For an Apple Account, change the password and make sure two-factor authentication is on (Apple).
5. Clear Safari data if it keeps coming backApple's steps: in Settings open Apps, choose Safari, and clear history and website data, picking a timeframe. You can also remove one site from History.
6. Report itReport the scam to the FTC at ReportFraud.ftc.gov.
What the scam is after

The FTC describes the usual script: a fake warning that seems to come from a well-known company urges you to call a number. The caller then asks for remote access to your device, claims to find malware and offers to remove it for a fee, and asks for payment by gift card, wire or bank transfer, cryptocurrency or a payment app.

Apple says the goal of these pop-ups is to get you to download harmful software or hand over personal information or money.

What a redirect is

A redirect sends you to a page you did not choose, often when you tap something harmless on a site. Fake virus alerts are one common place a redirect ends up. The steps above work the same way: leave the page, do not interact with it, and clear Safari data if it repeats.

Common questions

Can a website really tell me my iPhone has a virus?

Apple says pop-ups that claim your device has a security problem or a virus are typically fraudulent ads. Treat the message as a scam and close the tab.

Should I call the number on the warning?

No. The FTC says real security pop-up warnings never ask you to call a phone number.

What if I already called?

The FTC says scammers ask for remote access and payment. Do not give either. If you shared a password, change it and any account that uses the same one, then report it at ReportFraud.ftc.gov.

One option: a browser that blocks these as the page loads

SwatBrowser (also written Swat Browser) is an iPhone browser built to stop pop-ups, popunders, hijack redirects, fake virus alerts and click-trap overlays while you browse, with no setup. It is one way to see fewer of these pages; the steps above still apply to any page that gets through, in any browser.
