Advertising on a smartphone is not just an annoyance, but also a serious threat to data security. Pop-up windows, banners in system menus and intrusive notifications can turn using a modern gadget into a real nightmare. Often, users are faced with a situation where advertisements appear even on the desktop, covering application icons. The reasons can be different: from built-in advertising in the firmware to accidentally installed malware.
Fortunately, there are many effective ways to deal with unwanted content that do not require obtaining root access or flashing the device. In this article we will look at both standard system tools Androidand advanced methods for configuring network protocols. You will learn to find hidden sources of spam and block them at the level of the entire operating system.
You need to understand that there is no universal “Turn off all advertising” button, since the mechanisms for its delivery vary. However, the comprehensive approach described below will clean up the interface and speed up the work of your smartphone. We will start with the simplest steps and gradually move on to more in-depth settings.
Finding and removing the culprit of pop-up windows
Most often, the source of aggressive advertising is free applications installed by the user. These could be flashlights, QR code scanners, simple games, or memory “optimizers.” Such apps are often disguised as system utilities or do not have an icon in the menu, which makes them difficult to detect.
To find the pest, carefully study the list of installed apps. Go to Settings → Applications → All applications. Look for apps without a name or with a transparent icon. Also pay attention to the installation date - if the ad appeared recently, sorting by installation time will help you quickly figure out the culprit.
If you cannot find the application in the list, try the next method. When a pop-up window appears on your screen, do not close it immediately. Press the “Recent Apps” button (square or swipe up from bottom and hold). In the list of open windows you will see the name of the application that launched the ad. Remember its name and delete it through the settings.
⚠️ Attention: If the application is not deleted in the standard way and the “Delete” button is inactive, it may have received device administrator rights. In this case, go to Settings → Security → Device administrators and uncheck the suspicious app before deleting.
Before deleting an unknown application, take a screenshot of its page in settings. This will help you find information about the virus on the Internet if standard removal does not work.
Disabling personalized advertising in the system
The Company Google and smartphone manufacturers (such as Xiaomi, Samsung, Huawei) use an identifier system to display targeted advertising. While this does not remove ads completely, it does reset your advertising profile and limit the collection of data about your interests.
For devices with clear Android the path looks like this: go to Settings → Google → Advertising. Here you need to click on the “Delete advertising identifier” or “Reset advertising identifier” option. It is also recommended to activate the “Disable ad personalization” switch.
Smartphone owners Xiaomi (shell MIUI) need to perform additional steps, since the system has a built-in advertising service MSA. Go to Settings → Passwords and security → Access to personal data. Find it in the list msa and deny it access. After this, the system will ask for confirmation several times - you need to wait 10 seconds and click “Revoke”.

Ad blocking via Private DNS
One of the most effective and safe methods, which does not require installation of third-party apps, is to use the “Private DNS” function, available starting from version Android 9. This method blocks advertising at the network request level, preventing advertising banners from loading in browsers and many applications.
The essence of the method is to redirect all DNS requests through a server that automatically filters out domains of advertising networks. You don't need to configure anything manually, just enter the address of a special server. This does not affect Internet speed, but can slightly speed up page loading due to the absence of unnecessary content.
To activate, go to Settings → Connection and sharing → Private DNS (the path may vary slightly depending on the model). Select the “DNS Provider Hostname” mode and enter the following line:
dns.adguard.comAfter entering the address, save the settings. If there is an Internet connection, the system will accept the settings instantly. Now try to open a site that was previously full of banners - you will notice a significant difference.
The Private DNS method blocks ads in the browser and most applications, but may not work in official applications of large services (YouTube, social networks), since they use encrypted connections.
ℹ️ Information: The network settings interface may change with Android security updates. If you do not find the “Private DNS” item in the main settings, use the search in the settings by entering the query “DNS”.
Setting up the browser for surfing without banners
Even if you have set up a system block, the browser requires special attention. Standard browsers often have built-in data-saving features that may allow advertising content to pass through. The best solution is to use specialized browsers or configure extensions.
It is recommended to use browsers with built-in protection, such as Brave, DuckDuckGo or Firefox with an installed add-on uBlock Origin. Chrome also has basic protection: go to Settings → Privacy and Security → Safe Browsing and make sure that protection is enabled.
To completely clear pop-ups in any browser, you can prevent sites from showing notifications. Go to Settings → Applications → Your browser → Notifications and disable them completely. This will prevent spam from appearing in the “curtain” of notifications from visited sites.
| Browser | Built-in protection | Support extensions | Recommendation |
|---|---|---|---|
| Google Chrome | Basic | No (on mobile) | Requires configuration |
| Mozilla Firefox | Enhanced | Yes (uBlock Origin) | High |
| Brave | Maximum | No (own engine) | Optimal choice |
| Samsung Internet | Medium | Yes (via addons) | Good for Samsung |
Cleaning from hidden malware
If the previous methods did not help and advertisements continue to appear with alarming regularity, it is possible that a full-fledged virus trojan has settled on the device. Such apps can download other applications in the background or mine cryptocurrency using the resources of your phone.
For diagnostics, use the built-in service Google Play Protection. Open the store Play Market, click on the profile icon and select “Play Protection”. Click the "Check" button. The service will scan all installed applications for known threats.
In more complex cases, it is recommended to boot the device into Safe Mode. In this mode, only system applications are launched. If the ads disappear in safe mode, then a third-party application is to blame. To enter this mode, you usually need to hold down the power button, and then hold the “Power off” item on the screen for a long time until the corresponding request appears.
How to enter safe mode on different models?
On most smartphones: hold down the power button -> in the menu on the screen, long tap on “Turn off” -> confirm entering safe mode. On Samsung: turn off the phone, turn it on, and when the logo appears, hold down the volume down button until it boots completely.
While in Safe Mode, remove all recently installed applications, especially those that are suspicious. After rebooting to normal mode, the problem should disappear.
Prevention and hygiene of smartphone use
Preventing the appearance of advertising is easier than fighting it. The main cause of infection is carelessness when installing apps. Never download applications from third-party sources, forums or telegram channels if you are not 100% sure of their security.
When installing applications from the official store, carefully read the permissions that the app requests. If a simple flashlight asks for access to contacts, SMS and location, this is a clear sign of malware. Cancel the installation and find an alternative.
☑️ Rules of digital hygiene
You should also be careful when following links in messengers from unknown numbers. Phishing sites often use social engineering techniques to trick a user into downloading a “necessary codec” or “update” that is actually a virus. Is it safe to use ad blocking apps (AdBlock)?
Is it safe to use ad blocking apps (AdBlock)?
Using apps like AdGuard or Blokada safe if you download them from the official developer sites. They work as a local VPN filter without sending your data to third-party servers. However, they may consume additional battery power.
Will a factory reset help remove ads?
Yes, a Hard Reset will remove all applications and settings, returning the phone to its original state. This is guaranteed to remove any viruses, but before that, be sure to back up important photos and contacts.
Why do advertisements appear in games even if I have not installed suspicious apps?
Advertising inside free games is a legal way for developers to monetize. You can remove it only by purchasing a premium version of the game or turning off the Internet during the game, if the gameplay allows it.
Can advertising appear due to widgets on the desktop?
Yes, some news or weather widgets from unreliable developers can broadcast advertising banners. Try removing all widgets from the desktop and observing the behavior of the system.
