The appearance of intrusive advertising, pop-up windows and banners that overlap content is one of the most common problems of users of mobile devices based on Android. This is not only annoying and interferes with reading articles or watching videos, but also significantly reduces page loading speed and also wastes mobile traffic. Often, users are faced with a situation where advertising appears even on those sites where it did not exist before, or pops up on top of the desktop.
The reasons for this behavior can be different: from standard monetization of sites by resource owners to installation of malicious software or changes in system settings by the user himself. In some cases, the culprits are aggressive extensions or browser caches that store ad network data. Understanding the source of the problem is already half the success in the fight for a clean interface.
In this article we will analyze in detail all the available ways to remove a banner in a browser on Android. We'll cover both the built-in features of popular browsers and more advanced methods, including setting up private DNS and using specialized utilities. By following these recommendations, you can restore comfortable browsing on your smartphone or tablet.
Built-in ad blockers in mobile browsers
Modern browsers for mobile platforms are often equipped with their own modules for protecting against unwanted content. This is the easiest and safest way to start fighting banners and does not require installing additional software. However, the functionality of such built-in tools varies from developer to developer, and it is not always enabled by default.
For example, in the browser Opera or Opera Mini the ad blocking function is activated by one switch in the settings. It effectively hides most standard banners, but may miss some forms of native advertising integrated into article text. At the same time, Firefox for Android allows you to install full-fledged extensions, such as uBlock Origin, which turns the mobile browser into a powerful traffic filtering tool.
To activate protection in standard Google Chrome the situation is different. This browser does not have a built-in full-fledged ad blocker, but it does offer Safe Browsing and notification settings. Users often confuse pop-up windows with notifications from websites. To disable them, you need to go to the menu, select the section Settings → Notifications and block sending messages to suspicious resources.
The Samsung Internet browser has a built-in “Content Blocker” mode. For it to work, you need to additionally download a free extension from the Galaxy Store, for example, AdGuard Content Blocker.
It is important to understand that the built-in tools are good for basic protection, but they do not always cope with aggressive mining scripts or complex pop-ups. If the standard settings did not help remove the banner, you will need to move on to deeper methods of interfering with the system.
Configuring private DNS for blocking at the system level
One of the most effective and elegant solutions to the problem is to use the “Private DNS” function, available in Android 9 and newer versions. This method allows you to filter advertising traffic before it even reaches your browser, redirecting requests to advertising servers to nowhere.
The essence of the method is to change the standard DNS provider of your mobile operator to a special server that automatically blocks domains known as advertising sources. This works globally for all applications using standard network requests, not just the browser. To set up, you do not need root access or complex utilities.
To activate this function, follow these steps in the interface of your device:
- 📱 Open the application
Settingson your smartphone. - 🌐 Go to the section
ConnectionsorNetwork and Internet. - 🔒 Find the item
Private DNS(may be in the "Advanced settings" section). - ⚙️ Select the "DNS Provider Hostname" mode and enter the address:
dns.adguard.com. - ✅ Click "Save".
⚠️ Attention: After enabling Private DNS, some sites or applications may no longer work correctly if they use their own encryption protocols or specific domains. If you notice problems with the connection, temporarily return the setting to “Auto” mode.
The advantage of this method is its systematic nature. You don't need to configure each browser separately. Once you have entered the address, the protection begins to operate for other applications at the same time. This also helps save battery power since the device does not need to load heavy advertising scripts. dns.adguard.com, protection begins to operate for Chrome, Yandex Browser, DuckDuckGo and other applications at the same time. This also helps save battery power as the device does not need to load heavy ad scripts.
Removing malicious applications and clearing the cache
Sometimes the source of endless banners is not the site, but a malicious application installed on your device. Such apps are often disguised as useful utilities: “memory cleaners,” “flashlights,” “QR code scanners,” or even games. They may not have an icon in the menu, which makes them difficult to detect, but they actively generate pop-up windows on top of all open applications.
The first step in the fight against such a virus is a thorough audit of the list of installed apps. Go to Settings → Applications and carefully review the list. Look for apps that don't have a name, have a blank icon, or ones that you installed shortly before the problem started. Particular attention should be paid to apps with suspicious permissions, such as “on top of other windows.”
If you find a suspicious object, remove it immediately. In some cases, the Uninstall button may be grayed out because a malicious app has gained device administrator rights. To fix this, go to Settings → Security → Device Administrators and uncheck the suspicious app. Only after this can it be deleted in the standard way.
In addition to removing viruses, it is critically important to clear the browser cache. Ad networks often save data in local storage so they can show you targeted ads even after you change your settings. To clean, go to the settings of a specific browser, find the section Personal data or History and select item Clear cache. Make sure that the checkbox is on the cache, and not on saved passwords, if you do not want to lose them.

Using specialized blocker applications
If the built-in tools and DNS settings do not give the desired result, specialized blocker applications come to the rescue. They work on the principle of a local VPN tunnel: the application creates a virtual network interface on the device and filters all traffic passing through it, cutting off advertising requests.
The most popular and reliable solution in this category is AdGuard. This app offers advanced filtering options, including tracker blocking, phishing protection, and parental controls. It is important to note that due to policy Google Playmany full-fledged blockers are not available in the official app store. They must be downloaded from the official websites of the developers.
Installation of such software requires permission to create a VPN connection. This is standard procedure for such utilities and does not mean that your data is transferred anywhere. Filtering occurs locally on the device. After installation, you will be asked to select levels of protection: for example, ad blocking in the browser, in applications, or tracking protection.
| Application | License type | Root required | Features |
|---|---|---|---|
| AdGuard | Freemium | No | HTTPS filtering, tracker protection |
| Blokada 5 | Open Source | No | Lightweight, open source |
| DNS66 | Free | No | DNS filtering only, minimal battery consumption |
| AdAway | Free | Yes | Editing the hosts file, maximum efficiency |
Using third-party blockers may slightly increase battery consumption, since the filtering process requires processor resources. However, on modern devices with multi-core processors, this effect is almost invisible in everyday use.
Why don't blockers work on YouTube?
Applications like AdGuard block ads in the browser and most applications, but cannot remove ads inside the official YouTube application. This is due to the fact that the video stream and advertising are transmitted from the same Google domains, and it is impossible to separate them at the DNS level. To block ads on YouTube, modified clients or a Premium subscription are required.
Manual blocking through site notification settings
A common case that users mistake for a virus or banner is the legitimate sending of push notifications from websites. You may have accidentally clicked the “Allow” button when visiting a news portal or file hosting service, and now the site sends you notifications directly to the notification shade or shows pop-up windows on top of the browser.
These “banners” are not a virus in the classical sense, and antiviruses do not find them. The solution to the problem lies in managing browser permissions. You need to manually revoke permission to display notifications for specific domains.
The algorithm for Google Chrome looks like this:
- Open the browser and click on the three dots in the upper right corner.
- Go to
Settings → Site settings → Notifications. - In the "Allowed" list you will see the addresses of sites that can send you messages.
- Click on the address of the suspicious site and select Block or Delete.
A similar procedure is carried out in other browsers, such as Yandex or Firefox. In Firefox the path will be: Settings → Notifications. Regularly checking this list helps keep notifications clean and prevents annoying messages from dubious resources.
⚠️ Attention: If you see a notification but can't find the site in the allowed list, it may have come from an installed application and not from the browser. In this case, check the notification settings in the section
ApplicationsAndroid system.
Reset browser settings to factory settings
When none of the above methods help get rid of banners, and the behavior of the browser becomes unpredictable, it is advisable to completely reset its settings. This operation will return the browser to the state it was in immediately after installation, removing all extensions, configuration changes and accumulated data.
A factory reset is a drastic but effective measure. It is guaranteed to remove any hidden scripts or changes made by malicious extensions that may have embedded themselves deep into the user profile structure. Before performing this procedure, make sure you remember your master passwords or that they are synced with your account.
To perform a reset, go to Chrome go to Settings → Privacy and security → Clear history. Here, select the "All time" time range and check all the boxes, including cookies and site data, as well as site settings. In some versions of Android, a button is also available Reset settings at the very bottom of the browser settings menu.
Full reset of the browser removes all your personalizations, including themes, pinned tabs, and saved site exceptions. Use this method only if other methods have not worked.
After the reset, it is recommended to immediately set up a pop-up blocker in the security section to prevent re-infection. You should also refrain from installing dubious extensions in the first days after cleaning.
FAQ: Frequently asked questions
Why do ads appear even after installing the blocker?
This can happen for several reasons. Firstly, some sites use methods to bypass blockers (anti-adblock), detecting the presence of filtering and requiring it to be disabled. Secondly, if advertising is embedded directly into the content of an article (native advertising), it is technically difficult to separate it from the text. Third, check if your VPN blocker has turned off in the background due to the system saving power.
Is it safe to use Private DNS with the address dns.adguard.com?
Yes, it is safe. Servers AdGuard DNS are public and widely used by millions of users around the world. They do not log your personal data and do not transfer information to third parties. Their only task is to respond to DNS queries, blocking domains from advertising and tracker blacklists.
Can a virus penetrate a phone simply by opening a website?
On modern versions of Android (from 6.0 and higher), the security architecture (“sandbox”) greatly limits the capabilities of websites. Just by opening a page, it is difficult to infect your device with a serious virus. However, the site may force you to download an APK file under the guise of a Flash Player or codec update. If you install this file manually, infection will occur. Never download or install files offered by the site in the form of a pop-up window.
How to remove a banner that covers the entire screen and does not close?
If a banner blocks the interface and prevents you from pressing the “Back” button, try minimizing the browser with the “Home” button or a swipe gesture. Then go to Settings → Applications, find your browser and force stop it (Stop). After that, open the browser again - the frozen script should be reset. If this does not help, uninstall the application and install it again.
Does blocking ads affect the support of the sites I read?
Yes, many sites rely on advertising revenue. Complete blocking of advertising deprives authors of income. If you value the content of a particular resource, consider whitelisting it (exclusions) in your blocker settings or taking out a paid subscription if such an option is offered.
