The spontaneous appearance of advertising banners on top of the desktop or while using applications is one of the most common problems among smartphone users Huawei and Honor. This is not just an annoyance: intrusive windows that pop up on their own often indicate the presence of malware or incorrect configuration of installed apps. Owners of devices with a shell EMUI or new HarmonyOS face this regularly, especially after downloading content from unverified sources.
The nature of such pop-ups can vary from harmless but annoying push notifications from legitimate applications to full-fledged advertising viruses masquerading as system ones processes. To effectively solve the problem, it is necessary to diagnose the system, identify the culprit and apply blocking methods. In this article, we will analyze a step-by-step algorithm of actions that will help clear your screen of digital debris and restore the comfort of using your gadget.
Diagnostics of the source of pop-up windows
The first step in the fight against unwanted advertising is to accurately identify the application that generates it. Often, users mistakenly believe that the browser itself or the system is at fault, when the problem is caused by a recently installed flashlight, QR code scanner, or memory “optimizer.” In the latest versions Android devices Huawei have a built-in activity tracking mechanism.
When an advertising banner (suddenly appears) on the screen, do not rush to close it. Instead, press the Menu button (the square or three bars at the bottom of the screen) or swipe up from the bottom to open the list of running applications. In this list you will see a window card with advertising. Look at the icon and name of the application at the top of this card - this is the source of the problem.
If the advertisement appears as a notification in the curtain, press and hold the notification with your finger for a couple of seconds. The system will redirect you to the notification settings of a specific application. Its name will be indicated there. This is the fastest way to identify the culprit without installing third-party software. Sometimes the name may be hidden or replaced with empty space, which is a sure sign of a malicious app.
⚠️ Attention: If, when you try to open information about an application from the running tasks menu, the settings do not open or the phone freezes, you are probably dealing with an aggressive adware virus that blocks access to system functions.
Remember the icon virus application. Often, malware changes its name to a system name, for example, “System Update” or “Wi-Fi Service,” but their icon may differ from the standard Huawei system icons.
Removing malicious applications and hidden viruses
Once you have identified a suspicious application, it must be removed immediately. The standard procedure looks like this: go to Settings → Applications → Applications. Find the detected culprit in the list. If this is a regular application, the button Delete will be active immediately. However, some viruses have device administrator rights, which prevents them from being removed in the usual way.
If the delete button is inactive (gray), you need to revoke administrator rights. Follow the path Settings → Security → Device administrators. In this menu, find the suspicious application and uncheck it. Only then return to the applications menu and uninstall. Without this step, the system will block removal, considering the app critical.
Invisible applications are especially difficult. They do not have an icon in the menu or a name in the list of apps, but continue to work in the background. To find them, carefully scroll through the entire list of installed applications. An empty space with a right arrow to go to settings is a virus. You can also use safe mode to uninstall:
- 🔌 Hold down the power button and in the menu that appears, press and hold "Turn off" until you are prompted to enter safe mode.
- 🛡️ In safe mode, only system applications work, so the virus will not be able to start and interfere with removal.
- 🗑️ Go to the settings and remove all suspicious apps that were installed before the ad appeared.
- 🔄 Restart the phone in the usual way to exit safe mode.
☑️ Hidden virus removal algorithm
Setting up ad blocking in the Huawei browser
Often the source of pop-up windows is not a virus, but the settings of the browser itself. The built-in browser Huawei or popular Chrome may skip ads due to allowed notifications from dubious sites. The user may accidentally click “Allow” when visiting a resource, after which the site gets the right to send push notifications directly to the desktop.
To disable this function in the browser Huawei, open the application, click on the four dots in the lower right corner and select Settings → Privacy and Security → Site Notifications. Here you will see a list of all resources that are allowed to send notifications. Go through the list and remove any domains that are unfamiliar or that look suspicious. It is best to clear the list completely.
For browser Google Chrome the process is similar, but the path is slightly different. Open your browser, click on the three dots in the upper corner, select Settings → Site settings → Notifications. Disable the slider or remove specific sites from the allowed list. It is also recommended to enable built-in protection against malicious sites in the section Safe browsing.
| Browser | Path to notification settings | Recommended action |
|---|---|---|
| Huawei Browser | Settings → Privacy → Site notifications | Delete all domains |
| Google Chrome | Settings → Site settings → Notifications | Block everything |
| Yandex Browser | Settings → Sites → Notifications | Reset permissions |
| Opera | Settings → Privacy → Sites | Disable push notifications |
Why do ads appear even after clearing the browser?
Some sites use Service Workers technology, which allows them to work in the background even after closing the tab. Complete clearing of browser data (cache and cookies) is necessary to completely remove such scripts.
Using private DNS for global blocking
The most effective and modern method of combating advertising at the system-wide level is to use the function Private DNS (Private DNS). This technology, available in Android 9 and above, allows you to redirect all your phone's DNS requests through a server that automatically filters out advertising domains. This works not only in the browser, but also inside most free applications and games.
To configure on Huawei go to Settings → Wireless networks → Private DNS. If such an item is not in the main menu, use the settings search by entering the query “DNS”. Select the “ISP Hostname” (or “Manual”) mode and enter the address of a trusted blocker. The most proven and free solution is the service from AdGuard.
dns.adguard.comAfter entering the address, save the settings. Now all traffic on your device will be filtered. Advertising banners in applications will stop loading, since the phone simply cannot find the server on which they are located. This significantly saves traffic and battery power, since advertising content is not downloaded.
⚠️ Attention: When using a third-party DNS, some applications or sites may not work correctly or may not load at all. If you notice problems with Internet access, return the setting to “Auto” or “Disabled” mode.
Using dns.adguard.com blocks up to 90% of ads throughout the entire system without installing additional applications and without superuser rights (Root).
Analyzing installed applications and clearing the cache
Sometimes advertising is not a consequence of a virus, but of the operating features of legal free applications. Battery saving apps, phone boosters, document scanners and photo editors are often monetized by displaying full-screen banners. If you notice that advertising appears strictly after using a certain application, you should think about replacing it with an analogue without unnecessary water.
Also, the accumulated cache of the browser and system services may contain scripts that cause crashes and unwanted redirects. Clearing your cache regularly helps prevent this. Go to Settings → Applications → Manage applications. Find your main browser, click Memory and select Clear cache. Do not confuse with the "Reset" button, which will delete your passwords and history.
Pay attention to applications that you have recently installed, especially those that were not downloaded from the official store AppGallery or Google Play. Third-party installation files (APK) often contain modified code with built-in advertising. Removing such apps is the best prevention of future problems.
- 📱 Check the list of applications, sorting them by installation date.
- 🧹 Use the built-in "Optimizer" application (phone manager) to scan for viruses.
- 🚫 Avoid installing "cleaners" and “antiviruses” from unknown developers - they themselves are often a source of advertising.
Resetting settings as a last resort
If none of the above methods helped and ads continue to pop up with alarming regularity, malware may have embedded itself deep into the system or damaged system files. In this case, the only guaranteed solution is to completely reset the device to factory settings. This will delete all data, but is guaranteed to clear the phone of any viruses.
Before performing a reset, be sure to back up your important data: contacts, photos and documents. Use cloud storage Huawei Cloud or copy the files to your computer. After (backup), go to Settings → System → Reset → Reset phone. Confirm the action and wait for the reboot.
After resetting, the phone will be like new. In the first minutes of setup, it is important not to restore applications from a backup copy all at once. Install only what you need first and observe how the system works. If the advertisement does not appear, then the problem was in one of the older applications. Return the apps gradually so that in case of relapse you will understand which of them is malicious.
⚠️ Attention: A full reset will delete all your personal data, including photos, videos, correspondence and installed applications. Make sure you have an up-to-date backup before starting the procedure.
Is it possible to remove ads on Huawei without.root access?
Yes, absolutely. Using the Private DNS feature and manually blocking notifications in the browser does not require superuser rights. These methods are safe and do not void your warranty.
Why do ads appear even in a blocked state?
This is a sign of a serious virus that has permission to display on top of other windows and work in the background. Such an application should be urgently searched through the running tasks menu and deleted, possibly through safe mode.
Does enabled Private DNS affect Internet speed?
In most cases, the speed even increases, since heavy advertising content is not loaded. However, if the DNS server is overloaded or located far away, pages may take a fraction of a second longer to open.
Is it safe to use third-party ad blockers?
Apps like AdGuard require you to create a local VPN connection to filter traffic. This is safe, but may conflict with other applications that use VPN and slightly increase battery consumption.
