The constant appearance of pop-ups and intrusive banners in the browser Google Chrome turns using a smartphone into real torture. This is not just an annoyance: aggressive advertising often occludes content, consumes mobile traffic and can hide malicious code. Device owners are faced with a situation when the browser begins to behave unpredictably, opening new tabs without the user’s knowledge.
The reasons for this behavior range from harmless allowed notifications to serious viral infections that have penetrated the system. Removing advertising requires an integrated approach, since there is no single “turn everything off” button in the standard settings. You will have to analyze installed extensions, check the access rights of sites and, possibly, scan the device for hidden threats.
In this article we will analyze a step-by-step algorithm of actions that will help restore comfortable work on the Internet. We will look at both built-in protection tools Androidand third-party solutions that allow you to block trackers and banners at the DNS level or through specialized filters.
Configuring built-in filters and content blockers
The first and most logical step is to activate the built-in protection mechanisms, which developers Google have provided in the latest versions of the browser. These functions do not require the installation of additional software and work at the application core level.
Go to the settings menu by clicking on the three dots in the upper right corner of the screen. Find the section Settings → Privacy and Security. Here you will find the “Safe Browsing” option. Make sure that "Standard Protection" or “Enhanced Protection” mode is selected. This will allow the browser to automatically warn about potentially dangerous sites, which are often sources of intrusive advertising.
Next go to the section Site settings. Here lies a key content management tool. Find the "Pop-Ups and Redirects" option. It should be disabled by default, but if the slider is active, immediately set it to inactive. This will prevent sites from opening new windows on top of the current content.
⚠️ Attention: Even with blocking enabled, some sites may use scripts that disguise advertising as system notifications or interface elements. In such cases, standard filters may be ineffective.
It is also worth checking the “Advertising” option in this menu. Some versions Chrome have a function to block intrusive advertising that violates coalition standards Better Ads Standards. Activating this option will automatically hide banners that occupy more than 30% of the screen, or videos with autoplay and sound.
If you frequently visit news portals, add them to the exclusion list only if you fully trust the source. In other cases, it is better to keep the blocking enabled globally.
Managing permissions for web notifications
One of the most common reasons for the appearance of “advertising” on the desktop or in the notification panel is not a virus, but a self-granted permission to the site. Users often inadvertently click the “Allow” button when asked to display notifications, after which the site begins to spam push messages.
To fix this, you need to return to the menu Site settings → Notifications. You will see a list of all resources to which you have given access to send messages. Please study this list carefully. Any unfamiliar domain or site with a suspicious name should be blocked immediately.
To do this, click on the specific site address and select the option "Block" or “Delete”. After this, the site will no longer be able to send you notifications. If the list is too large and you don't want to deal with each item individually, you can completely disable the Notifications slider at the top of the screen. This is a radical but effective solution.
- 🔍 Check sites with names containing the words "news", "alert", "update" or a random set of characters.
- 🚫 Clear permissions for sites that you have not used in the last 3 month.
- ✅ Leave active only those resources that you use daily (mail, instant messengers, social networks).
Sometimes malicious scripts disguise themselves as system requests Android, claiming that you need to enable notifications to confirm that you are not a robot. Never agree to turn on notifications to check for a bot - it is always a scam. Real captchas work differently and do not require access to the notification system.
Search and remove malicious virus applications
If the browser settings did not help, and advertising continues to appear even outside of Chrome (for example, on the main screen), the problem lies deeper. Most likely, a malicious application is installed on your device that injects advertising modules into the system.
Go to the main settings of your smartphone and select the section Applications or Application Manager. Carefully scroll through the entire list of installed software. Look for apps that don't have an icon, have a clear name, or have a weird name made up of numbers and letters. Often viruses are disguised as “Memory Cleaner”, “Flashlight” or “System Update”.
Having detected a suspicious object, click on it and select the button "Delete". If the delete button is inactive (gray), it means that the virus has acquired device administrator rights. In this case, you need to go to Settings → Security → Device administrators, uncheck the suspicious application and only then return to deleting it.
⚠️ Attention: Some types malware may block access to settings or automatically close the removal window. In such cases, it is recommended to reboot the phone into safe mode before attempting to uninstall.
To search for hidden threats, you can use the built-in service Google Play Protection. Open the store Play Market, click on the profile icon and select “Play Protection”. Start scanning. This tool will check all installed applications for known virus signatures and offer to remove dangerous elements.

Using private DNS to block ads
Modern versions Android (starting from version 9) offer a powerful tool for blocking ads at the network level, which does not require the installation of third-party applications. This is the "Private DNS" feature, which encrypts your DNS requests and can redirect them through servers that block advertising domains.
To activate this feature, go to Settings → Connections → Other connection settings (the path may vary slightly depending on the smartphone model, for example Samsung or Xiaomi). Find the item “Personal DNS service” or “Private DNS”.
Select the “DNS provider host name” mode and enter the address of one of the popular blockers in the field. The most reliable and proven option is the service from AdGuard. Enter the following line:
dns.adguard.comSave the settings. Now all DNS queries from your device will go through the filters of this server. Advertising in the browser Chrome, as well as in most free applications and games, will stop loading, since requests to advertising servers will be blocked at the name resolution stage.
| DNS Service | Host Address | Efficiency | Working speed |
|---|---|---|---|
| AdGuard DNS | dns.adguard.com |
High | Stable |
| DnsFilter | family-filter-dns.dnsfilter.com |
Average | High |
| NextDNS | [ID].dns.nextdns.io |
Customizable | Depends on the region |
What to do if the Internet stops working after turning on DNS?
If the Internet disappears after entering the address, the selected server may be temporarily unavailable or your provider is blocking non-standard DNS requests. Try entering the address of another service from the table or temporarily switch the mode to “Auto”.
Clearing cache and browser data
Sometimes the problem lies not in viruses or settings, but in accumulated garbage. Corrupt cache files or outdated cookies can cause pages to display incorrectly and ad scripts to loop.
To resolve the problem, you must completely clear your browser data. Go to Settings → Applications → Chrome. Select "Storage" or "Memory". Here you will see two buttons: “Clear cache” and “Erase data” (or “Clear storage”)
Pressing the button “Erase data” will return the browser to the state immediately after installation. This means that all saved passwords, browsing history, bookmarks (if they are not synced with a Google account) and site settings will be deleted. However, this guarantees the removal of all malicious scripts that have become embedded in the local files of the browser.
After cleaning, it is recommended to restart the device and sign in again to your Google account to restore synchronization. If the advertising was caused by damage to the local database, this procedure will completely eliminate the problem.
Full data clearing is a radical method that solves 90% of browser software glitches, but takes time to re-customize.
Alternative browsers and extensions
If staff Google Chrome continues to demonstrate obsessive behavior even after all the manipulations, it makes sense to consider alternative solutions. The mobile version of Chrome does not support the installation of classic extensions (like on a PC), which limits blocking options.
An excellent alternative is the browser Brave. It is built on the same Chromium engine as Chrome, so the familiar interface and support for all sites are preserved. The main advantage is a built-in kernel-level ad and tracker blocker, which works out of the box without the need for complex configuration. Another option is to use browsers that support extensions, for example, or with the Anti-shock mode. In Brave Shields, which works out of the box without the need for complex configuration.
Another option is to use browsers that support extensions, e.g. Kiwi Browser or Yandex Browser with “Anti-shock” mode. IN Kiwi you can install a full extension uBlock Origin from the Chrome Web Store, which will provide a maximum level of protection comparable to the desktop version.
- 🛡️ Brave is the best choice for those who want privacy without unnecessary settings.
- 🧩 Kiwi Browser is ideal for users who need specific extensions.
- 🚀 DuckDuckGo - a browser with an emphasis on privacy and automatic blocking of trackers.
Switching to an alternative browser often solves the problem instantly, since these applications were originally designed taking into account the aggressive advertising landscape of the mobile data.
⚠️ Attention: Settings interfaces and menu item names may vary depending on the Android versions and manufacturer's shell (MIUI, One UI, ColorOS). If you do not find the described item, use the search inside your phone settings.
Frequently asked questions (FAQ)
Why do ads appear even after installing a blocker?
This can happen if advertising is embedded directly into the site content (native advertising) or if you have a malicious application installed that displays advertising on top of all windows, regardless from the browser. Check the list of installed apps.
Is it safe to use third-party DNS servers?
Yes, using public DNS from well-known providers (like AdGuard or Google) is safe. Moreover, it increases security because it encrypts your requests and prevents the ISP from spoofing website addresses.
Can a virus in Chrome steal my passwords?
A virus in the browser itself rarely steals passwords if they are stored in Google's secure storage. However, malicious extensions or phishing sites that ads redirect you to may try to trick you into entering your information. Always check the address bar.
How to distinguish a system notification from an advertising one?
System notifications usually come from specific applications (WhatsApp, Telegram, Gmail) and have their icons. Advertising notifications often come from sites with unclear names or without icons, and when you long press on them, the system will show which site the message came from.
Do you need to reset your phone to factory settings?
Resetting to factory settings is an extreme measure. You should resort to it only if none of the methods listed above helped and the device continues to work incorrectly. Before resetting, be sure to back up your important data.
