How to remove pop-up windows on Android when the phone is running

The appearance of unsolicited advertising banners that overlap the desktop or appear while using applications is one of the most annoying problems of users Android. It's not just visual noise; Often such windows indicate the presence of malware or incorrect browser settings, which can lead to leakage of personal data or a significant decrease in device performance.

In most cases, the culprits are free applications with aggressive monetization or sites that have received permission to send notifications. To restore the comfort of using a smartphone, it is necessary to conduct a comprehensive diagnosis of the system, identify the source of the irritant and apply appropriate measures to block or remove it.

This guide covers all aspects of solving the problem: from manually sending suspicious notifications to using specialized utilities. We will look at how to distinguish a software failure from a virus attack, and what steps to take if standard methods do not help.

Diagnostics of the source of pop-up advertising

First of all, you need to understand the nature of the windows. If ads only appear when you open the browser, the problem most likely lies in the cache or extensions. However, if banners pop up on the home screen or on top of other applications, this is a sure sign of a malicious process running in the background.

The easiest way to identify the culprit is to use the Recent Apps feature. Immediately after the ad appears, press the square bracket button (or swipe up from the bottom and hold your finger, depending on the model Samsung or Xiaomi). In the list of active processes, you will see an icon of the application that launched the advertising module.

Often such apps are disguised as system utilities: “Memory Cleaner”, “Flashlight”, “Virus Scanner” or even “Wallpaper”. They may not have a name or icon, appearing as a transparent square. Deleting such applications must be done immediately through the settings.

⚠️ Attention: If the application is not deleted through the standard menu or the “Delete” button is inactive (gray), then the malicious app has acquired administrator rights devices. You must first revoke these rights in the security section.

Blocking advertising notifications in the Chrome browser

A significant portion of pop-up windows originates from websites, which you accidentally allowed to send notifications. The Google Chrome browser, being the default on most devices, often becomes the gateway for such spam if settings are not configured correctly.

To block this channel, you need to go to your browser settings. Find the "Privacy and Security" or "Site Settings" section. Here you will see a list of resources that are allowed to show notifications. Study it carefully and remove all suspicious domains, especially those whose names you do not recognize.

It is also recommended to enable built-in pop-up protection. In the same site settings menu, find the “Pop-ups and redirects” item and make sure that the switch is in the “Blocked” position. This will prevent the automatic opening of new tabs with advertising.

For deeper cleaning, you can use the reset browser settings function. This will return all settings to factory defaults, but will not delete your bookmarks or browsing history. However, all site permissions will be revoked, which is guaranteed to stop the flow of spam.

Search and remove malicious applications

If blocking notifications in the browser did not help, it means that an application is installed on the device that generates ads systemically. Such apps are often downloaded along with useful software from unofficial sources or disguised as updates.

Go to Settings → Applications → All applications. Scroll through the list carefully. Look for apps you didn't install or ones that are missing an icon. Often viruses are hidden at the end of the list or have names similar to system processes, for example, “System Update” or “Wi-Fi Service”, but with typos.

If you cannot find a suspicious application in the general list, check the “Special access” section. In particular, pay attention to the “On top of other applications” item. apps that have the right to draw windows on top of the system interface are displayed here. Disable this permission for all applications except instant messengers and system utilities that you trust.

In the case where the application refuses to uninstall normally, you may need to boot into Safe Mode. This disables all third-party apps, allowing you to locate and remove the culprit without interference.

Reset settings to factory settings

When manual removal does not bring results and advertising continues to bother you, the most radical but effective method is to completely reset the device. This procedure deletes all data, applications and settings, returning the phone to the “as from” state. store."

Before starting the procedure, it is critical to create a backup copy of all important data: contacts, photos and documents. You can use Google Drive or transfer the files to your computer. After the reset, it will be quite easy to restore the information from the cloud.

To perform the reset, go to Settings → System → Reset settings. (reset to factory settings)". The system will ask for confirmation and entering a PIN code or pattern. The process may take from 5 to 15 minutes depending on the amount of memory.

Reset type	What is being deleted	Risk of data loss	Recommended use
Reset application settings	Permissions, notifications, background restrictions	None (data is saved)	When interface glitches
Reset network settings	Wi-Fi passwords, Bluetooth settings, mobile network	No	If there are problems with the Internet
Full factory reset	ALL data, applications, accounts, files	High (without backup)	In case of virus infection

⚠️ Attention: Make sure that the device is charged at least 50% before starting the reset. Interrupting the process due to low battery may damage the system partition and make it impossible to turn on the phone.

What to do if the phone does not turn on after a reset?

If after resetting the device is stuck on the logo, try entering Recovery mode (usually the power button + volume up) and select “Wipe cache partition”. This will clear temporary files without deleting personal data.

Using ad blockers and DNS

To prevent advertising from appearing in the future, you can use system blockers. One of the most effective and safest methods is to set up a private DNS. This method does not require installing additional applications and works at the network level.

In the Android settings (section “Connections” or “Network and Internet”), find the “Private DNS” option. Select the “ISP Host Name” mode and enter. address dns.adguard.com. This will redirect all DNS requests through AdGuard servers, which automatically cut off advertising domains.

An alternative is to install specialized applications such as Blokada or AdGuardThey create a local VPN tunnel on the device and. filter traffic. However, it is worth remembering that such apps can slightly increase battery consumption.

For users who often install applications from third-party sources, it is recommended to enable the scanner Google Play Protect. This built-in system regularly checks installed applications for malicious code and blocks potentially dangerous downloads.

Prevention and safe operation

After successfully cleaning the device, it is important to follow the rules of digital hygiene so that the problem does not return. Avoid installing applications from unknown sources. Even if you need a specific mod or game, try to find them on trusted forums or official websites of developers.

Be careful when installing any software. Read the permission screens carefully during installation. Often the checkboxes for installing additional “affiliate” software are already checked by default. Remove them before clicking Next.

Update your operating system and browser regularly Android constantly close vulnerabilities through which viruses penetrate the system. An outdated version of the OS is an open door for attackers.

⚠️ Attention: The settings interface may differ depending on the version of Android and the manufacturer's shell (MIUI, One UI, ColorOS). If you cannot find the specified menu item, use the search in the settings (magnifying glass icon at the top of the screen).

Frequently asked questions (FAQ)

Why ads even appear after uninstalling the application?

The application probably left behind service files or created a duplicate shortcut. It is also possible that the permission to show notifications remains active in the system settings for another related process. It is recommended to check the list of notifications in the settings and clear the browser cache.

Is it possible to remove system advertising in Xiaomi or Samsung shells?

Yes, in most modern shells you can disable personalized advertising. For MIUI, this is done through the settings “Passwords and security” → “Access to personal data”, where you need to disable the item msa. In Samsung, advertising is disabled in the privacy settings.

Is it safe to use anti-virus applications?

Use only proven solutions from well-known vendors such as Kaspersky, ESET or Dr.Web. Many free “cleaners” from the Play Market are themselves a source of advertising and can slow down the device instead of cleaning it.

What should you do if a pop-up window blocks the entire screen and does not close?

Try pressing the Home button or the app overview button to minimize the window. If this doesn't help, hold down the Power button and select Restart. In critical cases, removing the battery (if it is removable) or holding the power button for a long time to force shutdown will help.

Does ad blocking affect the operation of legal sites?

In rare cases, aggressive blockers can break the layout of sites or prevent video playback. If you encounter such a problem, add the problematic site to the white list (exceptions) in the settings of your blocker or DNS service.
