Random clicks on links, intrusive advertising and sudden opening of new tabs are a familiar problem for most mobile device users. When you're browsing a news site or looking for a recipe, the sudden appearance of a banner that covers the entire screen is not only annoying, but also creates a real security risk. Pop-up windows Often used by scammers to distribute malware or phishing.
Fortunately, the browser has built-in security mechanisms. Google Chrome allow you to effectively combat this phenomenon. In this article, we will look in detail at how to set up ad blocking, change site settings, and use additional tools to create a comfortable browsing environment. You will learn where the necessary switches are hidden and how to distinguish a legitimate notification from a dangerous script.
Built-in blocking settings in mobile Chrome
The first step to a clean Internet should be to study the standard capabilities of the browser. Google developers have implemented a powerful filter that blocks most aggressive ad formats by default. However, the settings can be reset by accidental clicks or system updates, so they must be checked manually.
To get to the desired section, open the application and click on the three vertical dots in the upper right corner. In the drop-down menu, select Settings. Next, scroll down to the section "Site settings". This is where all the key switches that control the behavior of web pages on your device are located.
Inside the site settings menu, find the item Pop-ups and redirects. Make sure the switch is in the Off (or Locked, depending on the translation version) position. If it is active, the browser will automatically interrupt scripts' attempts to open a new window without your knowledge.
If you accidentally allow pop-ups for a specific site, go to the settings of that site and click the "Reset Permissions" button to return the blocking to the default.
Also in this section it is worth paying attention to item Advertising. In modern versions of Android and Chrome, here you can enable additional protection against intrusive banners that violate the Better Ads Standards rules. Activating this feature will hide the most annoying interface elements.
Manage permissions for specific domains
Sometimes global blocking interferes with useful services. For example, some banks or government portals use pop-up windows to enter confirmation codes or open documents in a new window. In such cases, you do not need to disable the protection completely - just create an exception.
Return to the menu Site settings and select item "All sites". This will display a complete list of domains for which you have ever changed settings. Scroll the list or use search to find the address you need.
Click on the site name. You will see a detailed card with permissions: access to the camera, microphone, geolocation and, of course, pop-ups. If opposite the item Pop-up windows there is a checkmark "Allowed", click on it and select "Request" or "Block" to regain control of the situation.
⚠️ Attention: If you see unknown domains in the list of sites with allowed pop-up windows, immediately block them. This may indicate that you previously accidentally agreed to install a hidden script.
This targeted approach allows you to maintain the functionality of the necessary resources without putting all other tabs at risk. Regularly clearing this list of old and unnecessary addresses also helps maintain the device’s security at a high level.
☑️ Audit site permissions
Clearing cache and browser data
If blocking settings are enabled, but ads continue to appear, the problem may lie in the saved data. The browser stores cache, cookies and scripts, which may contain malicious code or outdated permissions to display ads.
For deep cleaning, go to main Settings Chrome and select section "Privacy and security". Click on item Clear history. Here it is important not only to delete your browsing history, but also to check the boxes “Cookies” and “Images and other files saved in the cache.”
Select temporary range “All the time”to ensure all traces of activity are removed. After confirming the action, the browser will reboot and all sites will require you to log in to your accounts again. This is a small price to pay for complete cleaning of potential threats.
| Data type | What is deleted | Impact on operation |
|---|---|---|
| History | List visited pages | Autofill in the address bar will disappear |
| Cookies | Authorization data and preferences | You need to log in to your mail and social networks again |
| Cache | Temporary files and pictures | Sites may load a little slower the first time |
After cleaning, the problem with annoying windows often resolves itself, since the scripts that initiate their opening are removed. If this does not help, it is worth considering more radical methods of protection.
Using extensions and third-party solutions
The mobile version of Chrome on Android, unfortunately, does not support installing classic extensions from the Chrome Web Store, unlike the desktop version. This limitation forces users to look for alternative ways to block ads and pop-up junk.
One of the effective solutions is the use of DNS filtering. You can configure a private DNS in the settings of Android itself, which will cut off advertising requests at the system level. To do this, go to Settings phone, section "Connections" or "Network and Internet", and find the item Private DNS.
Enter the address of a reliable blocker, for example dns.adguard.com. After saving the settings, most ad networks will stop loading not only in Chrome, but also in other applications. This significantly reduces the load on the processor and saves traffic.
Alternative browsers
If standard Chrome can't handle it, try browsers with a built-in blocker, such as Brave or Samsung Internet. They have powerful content filtering engines out of the box.
There are also special blocker applications that work through a local VPN tunnel. They filter traffic before it reaches the browser. Popular solutions like AdGuard allow you to fine-tune filters for specific categories of sites.
Protection against push notifications from sites
Often users confuse pop-up windows with push notifications. These are messages that appear in the Android notification shade even when the browser is closed. They usually occur after a user accidentally clicks "Allow" on a site's request to show notifications.
To stop this flow, open Chrome and go to Settings -> "Site settings" -> "Notifications". Here you will see a list of all resources that have the right to send you messages.
- 🔍 Carefully study the list and look for sites with suspicious names.
- 🚫 Click on each unnecessary site and select the option "Delete" or "Block".
- 🛡️ Turn off the general notification switch if you do not want to receive them from anyone at all.
Such notifications are often disguised as system messages about viruses or winnings, forcing the user to click on a dangerous link. Completely blocking this communication channel is the best way to protect yourself from social engineering.
⚠️ Attention: Never click “Allow” on sites with adult content, file sharing services or pirated cinemas. In 99% of cases, this will result in notification spam.
Diagnostics of malicious applications
If browser blocking is enabled, DNS is configured, and ads still appear as separate windows on top of other applications, the problem may not be in Chrome. Most likely, a malicious application is installed on your smartphone that generates this traffic.
Go to the Android settings, section Applications. Carefully review the list of installed apps. Look for apps without an icon, with a blank name, or ones you don't remember installing. Viruses are often disguised as “Flashlights”, “Memory Cleaners” or “QR Scanners”.
If you find a suspicious object, remove it immediately. If the “Delete” button is inactive (gray), it means that the application has received device administrator rights. In this case, go to Settings -> "Security" -> "Device administrator applications", uncheck the virus and only then delete it.
For prevention It is recommended to install a reliable antivirus from a reputable vendor, such as Kaspersky, Dr.Web or ESETand conduct a full system scan. This will help identify hidden threats that are not visible to the naked eye.
Pop-up ads when the screen is off or on the desktop is almost always a sign of a malicious APK file installed, and not a browser problem.
Frequently asked questions (FAQ)
Why do pop-ups even appear after enabling blocking?
This may be due to the fact that you previously gave permission to a specific site to show windows. Go to “Site Settings” -> “All Sites”, find the problematic domain and reset its permissions. Also check your phone for viruses.
Is it possible to install AdBlock on Chrome for Android?
Officially, the Chrome extension store does not support the mobile version of the browser on Android. However, you can use browsers with built-in protection (Brave, Samsung Internet) or set up a system DNS filter to block ads in all applications.
Is it safe to click “Close” on a pop-up window?
Not always. Some scam windows pretend to be a close button, but when clicked, they open a link or download a file. It is best to use the “Back” button on your phone or switch to another tab and close the problematic one through the task manager.
How to distinguish an Android system notification from a website notification?
Press and hold your finger on the notification in the curtain. If a menu appears with settings for a specific application (for example, Chrome) and a button to “Disable notifications from the site,” then this is the site. System notifications are managed in the general OS settings.
