How to Stop Pop-Ups on iPhone (Scams, Redirects, Spam Fixes)

To stop most pop-ups on iPhone, open Settings → Apps → Safari and turn on Block Pop-ups. That stops sites from opening new windows on their own. But "pop-up" covers a lot more than new windows: fake virus warnings, pages that keep redirecting, calendar spam and website notifications all feel like pop-ups, and each one has a different fix.

Find the kind you're seeing below. Every fix here is free and built into iPhone.

Turn on Safari's pop-up blocker

1. Open Settings, tap Apps, then tap Safari. On iOS 17 and earlier, go to Settings → Safari.
2. Turn on Block Pop-ups.
3. Turn on Fraudulent Website Warning too. Safari then warns you before opening sites known for phishing.

Block Pop-ups only stops new windows and tabs that a site tries to open without you tapping anything. It doesn't stop ads, banners or boxes drawn inside the page, which is why many people turn it on and still see "pop-ups". Keep iOS updated as well, since updates often include Safari security fixes.

"Your iPhone has a virus" pop-ups are scams

Safari never scans your phone for viruses, and Apple doesn't warn you about viruses through a web page. Alerts that say your iPhone is infected, that you've won a prize, or that you must call "Apple Support" are ads made to look like system warnings. Don't tap the alert, don't call the number, and don't install anything it suggests.

Be careful with the close button too. Apple notes that some pop-ups have fake close buttons that are really part of the ad. Instead, tap the address bar and type a new address, or open the tab view and close the tab with its own X.

Seeing the alert once, and closing it this way, does not mean your iPhone is infected.

Pop-ups that won't go away

Some scam pages reopen every time you launch Safari, or cover the screen so you can't reach the tab button. This sequence clears them:

1. Turn on Airplane Mode (and turn off Wi-Fi if it stays on), so the page can't reload.
2. Open Safari, tap the tabs button and close every tab.
3. Swipe up from the bottom of the screen and swipe Safari away to close it completely.
4. Go to Settings → Apps → Safari, tap Clear History and Website Data, choose All History, and confirm.
5. Turn Airplane Mode off and open Safari again.

Clearing website data signs you out of most sites, but it removes whatever the scam page saved. If pop-ups still appear afterward, check Settings → General → VPN & Device Management. If you see a profile you don't recognize and didn't install for work or school, tap it and remove it.

Pages that redirect you to other sites

If tapping anywhere on a page sends you to a different site, or the page jumps away while you read, that's an ad script on the page. The pop-up blocker usually can't stop this, because the redirect happens in the same tab rather than a new window.

An ad blocker is the real fix here, because it stops the ad script from loading at all. You can add a content blocker to Safari from the App Store and turn it on in Settings → Apps → Safari → Extensions, or use a browser with blocking built in. See how to block ads on iPhone for the options side by side.

Spam events in your Calendar

Fake "virus" or "prize" reminders that pop up from the Calendar app usually come from a calendar you subscribed to by tapping a link on a scam site. Deleting single events won't help, because new ones keep arriving. Remove the whole calendar instead:

1. Open the Calendar app and tap the Calendars button.
2. Tap the info button next to the calendar you don't recognize.
3. Tap Unsubscribe or Delete Calendar, then confirm.

If the spam came as an invitation from someone you don't know, open the event and tap Report Junk. Apple's guide to removing calendars and events has the details.

Notifications from websites

On iPhone, a website can only send notifications after you add it to your Home Screen as a web app and tap Allow. If one is spamming you, press and hold its Home Screen icon and remove it, or open Settings → Notifications, find the site's name in the list, and turn off Allow Notifications.

If notifications look like they come from an app you installed instead, that app's own settings in Settings → Notifications control them.

Banners, cookie boxes and sticky videos

Newsletter sign-ups, cookie banners, "open in app" bars and videos that follow you down the page are part of the page itself, so the pop-up blocker ignores them. In Safari on iOS 18 and later, tap the page menu in the address bar, choose Hide Distracting Items, tap the thing you want gone, then tap Done. Apple notes it doesn't permanently hide ads or other items that change often, so those can come back.

Kipzy, a free iPhone browser, handles these in three layers:

• The blocker: ads, trackers and pop-ups are blocked before they load, using EasyList and EasyPrivacy. That also stops most redirect ads. Settings has separate switches for Block popups and Blocked new tabs, and the Privacy Report shows what was blocked on each site.
• Hide this: tap any element on a page and choose Hide this. Kipzy remembers it for that site, and you can undo it.
• Clean this page: a Kipzy AI action that finds leftover pop-ups, sticky videos and banners. You see each one and choose what to remove.

Kipzy only blocks inside Kipzy. It won't stop calendar spam or notifications from other apps, so the fixes above still apply. More on the blocker on the ad blocker page.

How to allow pop-ups on iPhone

Some sites need a pop-up to work: bank and payment pages, school portals, and "Sign in with" buttons often open a new window. If a button does nothing, the blocker is probably stopping it.

1. Go to Settings → Apps → Safari and turn off Block Pop-ups.
2. Go back to Safari and try the button again.
3. When you're done, turn Block Pop-ups back on.

Safari on iPhone doesn't let you allow pop-ups for just one site, so it's all or nothing. In Kipzy, tap the shield in the address bar to turn blocking off for only that site. You can turn it back on later in Settings → Sites with blocking off.

Quick answers

Can an iPhone get a virus from a pop-up?

Just seeing a pop-up won't infect your iPhone. The risk is what it asks you to do: call a number, enter your Apple Account password or card details, install a profile, or subscribe to a calendar. If you did any of those, change your password and remove the profile or calendar as shown above.

Why do I still get pop-ups with Block Pop-ups on?

Most of what people call pop-ups today are drawn inside the page or are redirects, not new windows. Those need an ad blocker or Hide Distracting Items.

Does Chrome or another browser on iPhone block pop-ups?

Most iPhone browsers have their own pop-up setting in their own settings menu, separate from Safari's. Turning it on in Safari doesn't change other browsers.
