Additionally, check the Viral Protection section inside the application, where the recommendation point can be activated, and when you set up all the subsections of the Security app, you can ensure that there are no annoying pop-ups when scanning the device.
Cleaning the Mi Browser browser from news and

Elimination of advertising in system applications
Advertising integrations are present in many standard utilities, such as Explorer, Music, Themes and Video, each of which has its own recommendation switch, which must be disabled separately.
In the Themes app, ads are often found as banners on the home screen of the decor store. Go to the user profile (human icon) and in the settings, find the Display Ads. Similar settings are available in the Music app, where you can offer paid tracks or services.
File Explorer can also show recommendations from popular files or cloud services, open the Explorer menu, select settings, and disable all recommendations, which will speed up folders and make file navigation more direct.

Blocking Advertising on the Lock screen and in folders
One of the most annoying features of MIUI is the "Glance" which replaces the static lock image with the news feed with ads. On Redmi 9, this is often on by default. To return the normal lock, you need to change the lock screen settings.
Go to Settings → Always on screen and lock screen. Find the wallpaper carousel and turn it off. Then when you turn on the screen, you will see only the time and standard notifications, without news reports.
Advertisements in desktop folders appear as the "Recommended Apps" line at the bottom of the open folder, which happens when the system's recommendation function is turned on, and if you've followed the steps to disable the MSA and the recommendations in the settings, that item should disappear.
⚠️ Warning: If the adverts in the folders didn't disappear after all the settings, try to delete the folder and create it again. Sometimes the interface cache stores old ad data.
For full effect, follow the following steps:
- 🔒 Go to the lock screen settings and turn off the wallpaper carousel.
- 📂 Open any folder on your desktop and click on the folder name.
- 🚫 If there is a "Recommended Apps" switch, be sure to turn it off.
- 🔄 Reboot your smartphone to update your desktop (Launcher).
💡
Disabling the wallpaper carousel not only removes advertising, but also significantly saves battery power, as it stops the background loading of content.
Using DNS to block ads in apps
If system settings did not help remove ads in all applications, you can use the blocking method at the network level. DNS-server on the device allows you to filter traffic and block requests to known advertising servers.
This method is safe and does not require third-party software installation. Modern versions of Android (starting with 9.0) have a built-in Private DNS function. On Redmi 9, it is available in connection settings. You will need to prescribe the address of a special server that sifts out advertising traffic.
A popular and reliable solution is the use of dns.adguard.com, which blocks ads in browsers and most applications for free without slowing down the speed of the Internet connection, and is especially useful for games and applications where ads pop up at the wrong time.
dns.adguard.comTo activate, go to Settings → Connection and Sharing → Private DNS. Select DNS Host Name and enter dns.adguard.com. Save settings. Now all traffic on your device will go through the filter.
💡
If some applications or sites stop working after you turn on a private DNS, temporarily return the setting to Auto. Some corporate networks or specific services may block third-party DNS.
