Xiaomi Security Core: How to Disable Notifications

Owners of Xiaomi, Redmi and Poco smartphones with MIUI or HyperOS shells often encounter intrusive system messages that appear in the notification center.One of the most annoying sources of such alerts is a component called Security Core or Guardian Provider. It periodically issues alerts about potential threats, suggests installing an antivirus or simply reminds you to check the device.

Many users mistakenly believe it's a virus and start to panic, but it's actually a regular security mechanism built into the firmware that scans applications and protects against malicious code, but its overactivity can interfere with the comfort of the gadget, consuming battery power and distracting attention.

In this guide, we will go into detail what a system process is, why it is so active in notifying users, and what legitimate ways to restrict their activities are available. We will look at how to disable them through standard settings, the use of special codes, and deep system changes for advanced users.

What is a Guard Provider and why does it send notifications?

Guard Provider is a system application that serves as a shell for antivirus engines used by the security system. MIUI. By default, Xiaomi smartphones can be activated engines from Avast, AVL It's the component that scans the installed devices. APK-files, checks uploaded documents and analyzes the behavior of running programs in real time.

The main reason for notifications is because of aggressive marketing and reinsurance policies: the system can react to an application installation from an unknown source, detect questionable permissions, or simply suggest that the device be “optimized” to attract the user’s attention. Often these messages are classified as important, so they do not disappear even after cleaning the notification panel.

It's worth noting that the security kernel has deep permissions to access the system, it works at the Android kernel level, which allows it to intercept other applications, and it provides a high level of protection, but also creates the risk of false positives, when innocuous programs are flagged as dangerous, causing pop-ups.

Understanding the nature of this process is important before deciding to disable it. Completely removing a component can lead to errors in the GetApps app store or standard virus scanner, so it is important to act carefully when choosing a method of partial restriction of rights or disabling notifications rather than complete removal.

Basic settings of antivirus and scanner

The easiest and safest way to reduce notifications is to set up an antivirus built-in, which doesn't require superuser rights or a computer connection, but you need to open the standard Security app with a green shield icon that's preinstalled on every Xiaomi device.

Inside the app, go to the Antivirus section, where you can find settings (usually a gear in the corner or a three-dot menu) and turn off the option “Installation Monitor” or “Scan on Installation” in this menu, which will prevent the appearance of warning windows every time you download a new file from your browser.

Also in this section, it's often called "Receive recommendations" or "Security Notices," and disabling these switches removes the emails and offers to update antivirus databases that often come from partners like Avast. Once you do that, the system will be much quieter, but the basic protection will remain active.

⚠️ Warning: Disabling installation monitoring reduces protection when downloading files from unverified sources. APK-file-sharing.

Remember to run a full manual check periodically if you have disabled automatic monitoring, which will keep the system clean without constant visual noise, and in the settings of the application itself, you can find the Notifications section and uncheck all points except critical ones.

Disconnection through a special developer menu

There is a hidden menu in the MIUI shell that is designed to test security components, which allows you to control Guard Provider behavior in more detail than standard settings. To get there, open the Phone app and type in the code ##6484## or ##8484##. If the code doesn't work, try entering ##717717##, which is a direct path to the Guard Provider menu.

Once you enter the code, you will open an interface with a logo or a list of available providers. Here you will see a list of antivirus engines (e.g. AVL, Tencent, Avast). Select the one that is marked as active and click Uninstall or Disable. The system will request confirmation — agree.

This procedure does not delete the system file completely, but disables the specific antivirus engine, which is often the source of spam. After turning off, it is recommended to restart the device. If the menu does not open the first time, make sure that you have developer rights in the main settings of the system.

It is important to understand that after updating the firmware or the security application itself, the settings may reset and the engine will be activated again, so this method requires periodic checks, especially after major updates to the Android system or the MIUI shell.

Managing permissions and access to data

If you don't want to turn off the component completely, you can limit its capabilities by disabling notifications and network access. Go to Settings → Apps → All Apps. In the list, look for "Guard Provider" or "Security Core" (may be called "Security Core").

From the app menu, select Notifications and switch to Off, the most radical but effective method of dealing with visual noise, and go to Other Permits and deny access to your phone, SMS, and location if those are active.

Restricting mobile data and Wi-Fi for this application will prevent ad modules from loading and database updates, which will also reduce the frequency of notifications, but keep in mind that without Internet access, antivirus will not be able to check for new threats.

Using ADB to Advance Disconnect

For users who are not afraid of the command line, there is a more reliable method – disabling the component through the command line. ADB (Android Debug Bridge. This way doesn't require root rights, but it necessitates connecting your smartphone to your computer. USB» menu "For developers».

Connect your phone to your PC, install the ADB drivers and platform. In the command line, type in the command line to search for the package: adb shell pm list packages | grep guard. You will see the name of the package, usually com.miui.guardprovider. To disable it, use the command:

adb shell pm disable-user --user 0 com.miui.guardprovider

This command freezes the application for the current user, disappears from the installed program list and stops running, consuming resources, and sending notifications, and if you want to return it as it was, just replace the word disable-user with enable in the same command.

⚠️ Attention: Use ADB Disabling critical system packages (non-Guard Provider) can result in a cyclical device reboot (bootloop).

The advantage of the ADB method is that it does not usually return components that are disabled to an active state, making it one of the most stable solutions to the intrusive security core problem in the long run.

Impact on autonomy and productivity

Many users are wondering: is the game worth the candle? The constant operation of the Guard Provider in the background really affects power consumption. The process of scanning in real time requires periodic access to the processor and disk memory, which prevents the device from going into deep sleep mode.

Disabling notifications and background activity of this component can add 5 to 15% of battery life per day, especially on older smartphone models where CPU resources are limited, and frees up RAM, making the MIUI shell interface more responsive.

However, if you are actively using your device to work with external files, it can be risky to completely disable the protection, in which case it is better to leave the component on, but strictly limit its rights to notification, as described in the previous sections.
