How to Stop Browser Pop-Up Ads and Redirects

This guide walks you through removing pop-up ads and unwanted redirects from your browser. These issues are almost always caused by a combination of a few common factors: malicious browser notifications, unwanted extensions, or a hijacked browser shortcut. The steps below will help you identify and eliminate each cause, restoring a clean and quiet browsing experience. You will need access to your browser’s settings menu and, in some cases, the ability to uninstall programs from your computer.

What You’ll Need

Your computer or mobile device
Administrator access to your operating system (to uninstall programs if needed)
A few minutes of uninterrupted time

Step-by-Step

These steps are ordered from the most common cause to the least common. Complete them in order and check if the problem is solved after each major section.

Close the pop-up without clicking. If a pop-up or redirect appears, do not click anywhere inside it. Click the “X” in the corner of the tab or press Ctrl+W (Windows) or Cmd+W (Mac) to close that specific tab. If the page keeps opening new tabs, close the entire browser window.
Check for unwanted browser notifications. Pop-up ads that appear in the corner of your screen (not inside the browser window) are usually notifications from websites. To stop them:
- Chrome, Edge, Brave: Click the three-dot menu (top right) > Settings > Privacy and security > Site settings > Notifications. Look for any website you don’t recognize or that seems suspicious. Click the three dots next to it and select Block or Remove.
- Firefox: Click the three-line menu > Settings > Privacy & Security > scroll to Permissions > Notifications > Settings. Remove or block any unknown sites.
- Safari (Mac): Go to Safari > Settings > Websites > Notifications. For any site you don’t want, select Deny and uncheck “Allow websites to ask for permission to send notifications.”
Disable or remove suspicious browser extensions. Extensions are the second most common cause. To review them:
- Chrome, Edge, Brave: Type chrome://extensions (or edge://extensions, brave://extensions) in the address bar and press Enter. Look through the list. Disable any extension you don’t remember installing, or any that seems unrelated to its stated purpose. If pop-ups stop, delete that extension entirely.
- Firefox: Type about:addons in the address bar. Go to Extensions and disable or remove anything unfamiliar.
- Safari: Open Safari > Settings > Extensions. Uncheck or uninstall anything you don’t recognize.
Reset your browser’s homepage and search engine. A hijacker may have changed these settings. In your browser’s settings, look for On startup and Search engine. Set the homepage to a site you trust (e.g., google.com) and choose a standard search engine (Google, Bing, DuckDuckGo). If the setting reverts after you change it, a program on your computer is forcing it.
Check for unwanted programs on your computer. Some adware installs itself as a regular program. On Windows, go to Settings > Apps > Installed apps. Sort by date installed and look for anything you don’t recognize, especially if it was installed around the time the pop-ups started. Uninstall those programs. On Mac, go to Applications in Finder and drag any suspicious apps to the Trash, then empty the Trash.
Check your browser shortcut for a hijacked target. Right-click your browser’s desktop shortcut and select Properties (Windows) or Get Info (Mac). Look at the “Target” or “URL” field. If it contains a website address after the browser’s .exe path, delete that extra text. For example, the target should end with chrome.exe, not chrome.exe http://bad-site.com.
Clear your browser cache and cookies. This removes any stored scripts that might be causing redirects. In your browser settings, find Privacy and security > Clear browsing data. Select “All time” and check “Cookies and other site data” and “Cached images and files.” Click Clear data.
Run a malware scan. Use the built-in Windows Security (Windows) or a reputable third-party scanner. On Windows, go to Settings > Privacy & security > Windows Security > Virus & threat protection > Scan options > Full scan. On Mac, run a scan with a trusted antivirus tool if you have one installed.
As a last resort, reset your browser completely. This removes all extensions, settings, and temporary data. It will log you out of websites but it is the most thorough fix.
- Chrome: Settings > Reset settings > Restore settings to their original defaults.
- Edge: Settings > Reset settings > Restore settings to their default values.
- Firefox: Help menu > More troubleshooting information > Refresh Firefox.
- Safari: There is no one-click reset. You must clear history, remove extensions, and reset the homepage manually.

Common Mistakes

Clicking “Allow” on notification prompts. Many sites ask “Allow notifications?” as soon as you visit. Always choose “Block” unless it’s a site you trust and genuinely want notifications from (like email or calendar).
Only closing the pop-up window. Closing the pop-up does not remove the cause. You must find the source (extension, notification, or program) and remove it.
Installing “free” software from unfamiliar sites. Many adware programs come bundled with other downloads. Always choose “Custom” installation and uncheck any extra offers.
Ignoring the browser shortcut. A hijacked shortcut can redirect you every time you open the browser, even if all other settings are correct.
Running only a quick malware scan. Quick scans often miss adware. A full system scan takes longer but is far more effective.

Tips

Use a pop-up blocker. Most browsers have a built-in blocker. In Chrome, go to Settings > Privacy and security > Site settings > Pop-ups and redirects and ensure it’s set to “Don’t allow sites to send pop-ups or use redirects.”
Keep your browser updated. Updates often include security fixes that block known adware techniques.
Be selective about extensions. Only install extensions from official stores (Chrome Web Store, Firefox Add-ons) and read reviews before installing.
Use a content blocker for extra protection. Extensions like uBlock Origin (available for Chrome, Firefox, and Edge) can block many ads and malicious scripts before they load.
Check your phone too. If you see pop-ups on your phone, repeat the same steps: check notifications, review extensions (in Chrome for Android, go to Settings > Extensions), and clear browsing data.

Troubleshooting

Pop-ups return after following all steps. This usually means a program is reinstalling the adware. Reboot your computer in Safe Mode (Windows: hold Shift while clicking Restart; Mac: hold the power button until “Loading startup options” appears), then run a full malware scan again. If the problem persists, consider using a dedicated adware removal tool from a reputable security vendor.

You can’t open your browser settings. If the browser immediately redirects before you can click anything, try opening the browser in “Incognito” or “Private” mode (Ctrl+Shift+N on Windows, Cmd+Shift+N on Mac). Extensions are usually disabled in this mode, allowing you to reach the settings. Alternatively, uninstall the browser completely and reinstall a fresh copy.

The settings revert after you change them. This is a sign of a hijacker program running in the background. Go to your task manager (Ctrl+Shift+Esc on Windows, Activity Monitor on Mac) and look for unfamiliar processes. Search the process name online to see if it’s known adware, then end it and uninstall the associated program.

Pop-ups only appear on one specific website. This is likely not adware but the website’s own aggressive advertising. Use a content blocker for that site, or avoid visiting it. You can also block the site’s notifications and pop-ups individually in your browser settings.

You see “Your computer is infected” warnings. These are fake. Do not call any phone number or click any button on the page. Close the tab and run a real malware scan. These warnings are designed to scare you into paying for fake support or installing more malware.

Frequently Asked Questions

Why am I suddenly getting pop-ups when I never had them before?

Most often, you accidentally clicked “Allow” on a notification prompt, or you installed a free program that came bundled with adware. It can also happen after visiting a compromised website that exploits a browser vulnerability, which is why keeping your browser updated is important.

Are pop-up ads dangerous?

Most are just annoying, but some can be dangerous. They might trick you into downloading malware, entering your password on a fake login page, or calling a fake tech support number. It’s best to never interact with them and remove the source.

Will resetting my browser delete my saved passwords?

In Chrome and Edge, a reset will clear your cookies, extensions, and temporary data, but it will not delete your saved passwords or bookmarks if you are signed in and have sync enabled. In Firefox, refreshing will keep your bookmarks and passwords. To be safe, export your passwords or bookmarks before resetting.

Can a pop-up blocker stop all pop-ups?

No. A pop-up blocker stops most traditional pop-up windows, but it cannot stop redirects or notification-style ads. Those require the steps above, like disabling notifications and removing malicious extensions.

Is adware the same as a virus?

Not exactly. Adware is a type of unwanted software that displays ads, while a virus is designed to damage or take control of your system. However, adware can sometimes install other malware, so it should be removed promptly.

Do these steps work on mobile browsers?

Yes, the same principles apply. On an iPhone, go to Settings > Safari and block pop-ups and check for unknown profiles. On Android, check Chrome’s site settings for notifications and review installed apps for anything suspicious. The steps are slightly different but the logic is the same.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
