If ads keep popping up on your phone, you're not alone. Fortunately, there is a way to stop them before they bug you even more or become a malware or identity fraud threat. These interruptions start with a simple "tap pop-ups" or "push notifications allowed", then escalate into full-screen redirects every time you open Chrome, Safari, or an app.
Our research found hundreds of Play Store apps involved in an ad fraud campaign, accumulated over 60 million downloads, and silently spammed users with full‑screen ads and phishing attempts.
What's changed? Attackers are now using AI to write more convincing SMS scams and mimic banks, couriers, family members, and more. They go way beyond the broken-English spam texts of the past.
Hence, this guide is here to show you exactly how to:
Pop-ups and redirects can be signs of adware, malicious app behavior, or embedded tracking scripts that have latched onto your browser or system permissions. These unwanted ads can appear even when you're not actively using your device and are designed to push shady products, collect your data, or redirect you to get phished.
In many cases, the source is a specific app you've recently installed. Or perhaps, it's the active apps running aggressive ad SDKs in the background.
Some pop-ups hijack your address bar or browser “home screen” settings to reroute your home page or force open tabs with scam alerts (like fake virus warnings or prize claims). You may not even see an app icon, just random dialogs or loops of individual pop-ups.
In our experience, if you’re constantly seeing full-screen ads, browser tabs opening on their own, or fake warnings that your phone has a virus, it's time to open your Android settings or iPhone controls and run a phone scan with a virus scanner.
Scam texts in 2025 are starting to not look like scams, which makes them dangerous. They mimic delivery services, banks, or people in your contacts, and get through your phone’s default spam filters.
It all comes down to you and your security hygiene. So, here’s how to spot the signs:
Screen pop-ups keep interrupting your phone can be a cause of aggressive ad SDKs inside apps that seem harmless. Think flashlight tools, wallpaper apps, budget games, or “cleaner” utilities.
Here’s how to track down the culprit step by step.
For Android users:
Safe Mode disables all third-party apps. That makes it easier to test whether the pop-ups are system-related or coming from an app you installed.
Go to Android Settings > Apps > See all apps > Sort by Most recent
This helps you spot anything installed shortly before the problem started. If you see apps with no name, blank icons, or ones you don’t remember downloading, uninstall them immediately.
Head to Settings > Apps > Special app access > Display over other apps
Look for apps (especially ones you didn’t install on purpose) that have permission to draw overlays. Open Android Settings, tap "permission" and revoke access for any app that shouldn’t have this power, like camera filters, file managers, or battery savers.
Apps that abuse notification permissions can sneak in pop-ups even if they’re legit-looking, so it's best to disable notifications. Follow these steps:
Common pop-up ads can come from malicious web scripts. On your Samsung device, force‑stop the Chrome app (or your default browser) via Settings, then clear Storage > Clear Cache and Clear Data. This removes any website settings, cookies, or redirects causing malicious pop‑ups.
Additionally, clear browsing data from Chrome > Settings > Privacy and security. Reset browser settings to default if you're redirected often
When a full-screen ad appears, swipe up to show your recent apps (or tap the Recents button). Long-press the app preview and tap App info to identify the exact app behind it.
Bitdefender detects known adware libraries, fake utility apps, and stealthy malware SDKs, including those that slip past Google Play Store checks. It also alerts you to apps with excessive permissions or hidden behavior. Use it after cleanup to confirm your device is safe and ad-free.
When ads persist despite these steps and disturb you with persistent malware, a full reset may be needed. Back up important data and settings on your Android device, then perform Settings > System > Reset > Factory data reset from the drop-down menu.
For iPhone users:
Go to Settings > Apps > Safari > Clear History and Website Data
Many pop-ups on iOS are caused by malicious web scripts or redirects embedded in cookies and browser data.
Follow these steps on your iOS device:
If you see any unknown or suspicious profiles installed, remove them. These can control Safari behavior, network settings, app permissions, or ad privacy settings.
Go to Settings > Calendar > Accounts
If you see a calendar you didn’t subscribe to (like one with spammy events), delete it. Scammers use this tactic to overrule ad blockers by pushing alerts through iCal.
Bitdefender detects phishing links in Safari, scam iMessages, and malicious configuration profiles. These issues can fly under the radar of Apple’s default protections, so the security app is especially helpful for flagging fake virus warnings or login scams coming from ads, calendar invites, or rogue redirects.
If you've gotten rid of the offending app or annoying pop-up, wait up – the job isn’t done yet. Now it’s time to make sure you remove pop-up ads for good, so they don't come back again. Here’s how to block pop-up ads properly.
For Android:
1. Avoid apps with excessive permissions
Don’t install apps that ask for access to your location, contacts, camera, or notification control unless it’s clearly necessary.
2. Block personalized ads and tracking IDs
Go to Settings > Google > Ads > Delete advertising ID. This removes behavioral profiling that often results in spammy or aggressive ad targeting.
3. Regularly review app permissions
Check under Settings > Privacy > Permission Manager. Revoke microphone, SMS, and “draw over apps” access from anything that shouldn’t need it.
4. Enable Play Protect and verify app sources
Check if you have Play Protect on (Settings > Security > Google Play Protect). Only install apps from Google Play or verified developers to avoid having malware installed.
For iPhone:
1. Turn off the personalized ad experience
Go to Settings > Privacy & Security > Apple Advertising > Turn off Personalized Ads. This reduces the behavioral profiling that ad networks use to serve more clickable ads from app developers.
2. Disable automatic calendar invites
Go to Settings > Calendar > Accounts > Fetch New Data and set suspicious accounts to “Manual” or remove them entirely.
3. Remove rogue configuration profiles
Check Settings > General > VPN & Device Management. Delete anything you didn’t install yourself. These profiles are sometimes used to manipulate ad behavior or install spam filters outside of App Store control.
Take these universal steps:
Maybe you tapped a fake delivery update or hit “Close” on a pop-up that secretly triggered a redirect. Well, it’s not game over, as long as you act fast.
If you’re stuck in a redirect loop or fake alert:
Malicious ads leave behind tracking cookies or exploit session tokens. Clean them out.
If you accidentally gave permission (like location, storage, or camera access), undo it.
Android – Settings > Privacy > Permission manager. Review Camera, Microphone, Storage, select App Notifications, and revoke access from unfamiliar apps, likely to be the ad-serving apps.
iOS – Settings > Privacy & Security > tap each category (e.g., Microphone, Camera) and disable for apps you don’t recognize or trust. They could be the problematic apps that send pop-ups.
If the fake site looked like a bank or login page and you typed anything, assume it’s compromised.
If you reused that password anywhere else, change it there too.

If anything feels off, reset the device to factory settings after backing up important data.
Built-in protections like Google Play Protect and Apple’s App Store review process are better than nothing. However, both miss key layers, like:
That's why Bitdefender developed a one-stop shop solution for both iOS and Android, which will help you take your phone's security and browsing experience to a whole new level. Here's why:
Neither Google nor Apple scans for malicious behavior after an app is installed. Bitdefender does.
It continuously monitors what apps actually do on your device, beyond what they claimed in the store. That means it can flag suspicious behavior from apps that passed review but later loaded hidden adware SDKs, started draining data, or requested dangerous permissions.
For example, if you've downloaded a QR scanner or wallpaper app, Bitdefender’s behavior-based engine can spot if it suddenly starts pushing full-screen ads or abusing “draw over apps”.
Play Protect doesn’t scan links in SMS, WhatsApp, Instagram DMs, or email apps. On both Android and iPhone, Bitdefender watches for dangerous URLs no matter where they show up (Safari, Chrome, or inside other apps) and stops them from loading in the first place.
Bitdefender gives you a VPN with system-wide encryption, even on Android, even in third-party apps. You can protect your device traffic (up to 200MB/day included) on public Wi-Fi, banking apps, or when you’re using mobile hotspots with no additional setup.
You’re in an airport, using the lounge Wi-Fi to check invoices in your banking app. Bitdefender encrypts all traffic. And if you think that 200MB/day will not suffice, you can always upgrade to the Premium VPN for unlimited traffic.
Bitdefender’s Account Privacy feature continuously checks if your email, passwords, or accounts show up in data breaches. That's a step Play Protect doesn’t offer at all, and iOS only partially supports via iCloud Keychain.
So, if your Uber account email appears in a new breach, Bitdefender flags it instantly. This way, you can change your credentials before that password is reused in phishing attempts or sold on the dark web.
If you’ve followed the steps above and ads keep returning, it’s time to scan your entire device.
