Many users of smartphones Xiaomi, Redmi and POCO They're faced with a situation where the built-in protection starts to interfere with the operation of the device. MIUI Security can block the installation of applications from third-party sources or compulsively check files, consuming battery power. Understanding how to properly manage these settings is necessary for comfortable use of the gadget.
In this article, we will look at the nuances of the built-in guard, whether to turn off the protection completely or to fine-tune it enough, and we will also look at methods to combat intrusive advertising, which often masquerades as system warnings.
It's worth noting that ignoring safety guidelines completely can lead to risks, but in the right hands, MIUI becomes a flexible tool that works exactly as the owner wants it to, not as the default engineers intended.
Why turn off protection on Xiaomi
The main reason users are looking for a way to deactivate is because of the system’s aggressive behavior when installing. APK-The built-in scanner can block modified apps, games or utilities that have not been certified by Google Play.This often annoys advanced users who know the source of the file.
Another aspect is performance: real-time background checks put a strain on the processor. On budget models like the Redmi Note or the POCO M series, this can cause micro-freezes of the interface. Disabling redundant services helps free up RAM resources.
⚠️ Attention: By disabling system protection, you take responsibility for data security.Install applications only from trusted sources.
Privacy is also a concern, because local antivirus databases can be updated and transmitted to the developer's servers, and for those who value privacy, minimizing telemetry is a priority.
Disabling the APK installation scanner
The most common scenario is to block the application installation immediately after downloading, the system issues a warning about a potential threat and suggests that the file be deleted, and to get around this, you do not need to turn off all protections completely.
You need to go to the security settings. Open the Security app (the shield and lightning icon). In the upper right corner, click on the gear icon to get into the settings menu. Here we are interested in the Security Scanner.
Inside this menu, find the Check When Installation or Scan Before Installation, which allows you to install applications without constant checks, but the system can still show a one-time warning when you first start.
☑️ Scanner settings
It's important to distinguish between installation lock and launch lock. Sometimes MIUI labels an application as risky but lets it run once it's confirmed. If you want to ignore it completely, use the following method.
Application Management Security
Unlike pure Android, Xiaomi’s security app is system-based and has extended rights. You can’t just remove it, but you can limit its activity, which will help reduce the number of background processes.
To start, go to Settings → Applications → All apps. Find Security (or Security) in the list. Click on it and select AutoStart. Make sure it's turned off if you don't want the service to run all the time.
There's also a "Other Permissions" menu, where you can turn off location, microphone, or contacts if the antivirus requests them without the explicit need, which will increase the overall privacy of the device.
⚠️ Attention: Full security stop through ADB-commands can lead to unstable system operation and errors in the interface.
Some users try to uninstall the application completely via a computer, which requires an ADB connection and a command to:
adb shell pm uninstall -k --user 0 com.miui.securitycenterUsing this command makes the antivirus inaccessible to the current user, and it can only be returned by resetting the settings to a factory state or re-installing through ADB.

Fighting Advertising Notifications
Often, by "antivirus work," users mean pop-up ads, the system can report that "5 risks have been found," when in fact this is a marketing ploy to promote cleanup or optimization, and this is solved through advertising settings.
In the same Security app menu, look for Settings. Scroll down to Get Recommendations or Get Recommendations. Turn off this switch. This will remove most of the intrusive sentences.
You can also check the global settings of your adverts. Go to Settings → Passwords & Security → Access to Personal Data. Find the MSA (MIUI System Ads) service and turn it off. The system will ask you to wait 10 seconds before you can stop access.
Disabling msa is a key step to clean interface operation, and without this step, even a disabled antivirus can continue to display banners through system notifications.
💡
The msa service may try to turn on itself. If the ad reappears, just repeat the procedure of disabling access to personal data.
Comparison of built-in protection and third-party solutions
Should you install Dr.Web, Kaspersky or ESET on Xiaomi? the built-in engine is based on Avast or AVL bases, which provides a decent level of protection for the average user.
Third-party antiviruses have a broader range of features: anti-thief, covert mode, call protection, but they consume significantly more resources, and on devices with 4GB of RAM or less, this can be a noticeable problem.
| Characteristics | MIUI Security | Third-party antivirus |
|---|---|---|
| Depth of integration | System (Root rights are not required) | Limited by Android rights |
| Impact on the battery | Optimized by the manufacturer | Often high consumption |
| Virus databases | Updated via MIUI | Frequent updates from the vendor |
| Advertising | Present (can be turned off) | Depends on the version (Free/Pro) |
For most use cases, the built-in scanner + common sense bundle is optimal, and installing heavy third-party software is only justified when dealing with sensitive data or visiting risky resources.
Frequent problems after disconnection
After security changes are made, there may be side effects, such as the GetApps app store may stop updating or fail to check licenses, because many Xiaomi services are tied to a single security module.
There are also possible false positives when connecting to public Wi-Fi networks, the system may stop alerting an unsecured connection if the relevant modules have been affected by the changes, and the user should be more careful when using open networks.
In rare cases, the security application icon disappears, which doesn't mean it's completely removed, often just clearing the launcher's cache or restarting the device to get the icon back in place.
⚠️ Note: If after disabling components, the phone began to restart in a loop (bootloop), you need to boot in Recovery mode and reset settings.
It is critical to preserve the original APK-System applications before deleting them through ADB. This will restore the performance of the smartphone in the event of a fatal error.
💡
Complete removal of system components is justified only for experienced users who understand the risks of loss of warranty and system stability.
