Xiaomi, Redmi and POCO smartphone owners often face intrusive notifications that security requires a deep cleanup of the device. MIUI Security’s built-in algorithm aggressively suggests removing the cache, closing background processes, and checking files for threats. While this feature is designed to protect, in reality it often only consumes battery power and interrupts user experience.
Many users mistakenly believe that deleting such notifications requires obtaining Root rights or reflashing the device to the global version. This is not true. HyperOS or MIUI shell system settings allow you to flexibly control the behavior of the built-in scanner. You do not need to be an engineer to prevent the Security app from interfering with your gadget without asking.
In this article, we will take a look at how to turn off automatic scanning when installing applications, remove permanent pop-ups, and adjust power saving settings. We will look at both standard methods through the settings menu, and more advanced methods through hidden engineering menus, which will allow you to regain full control of the device.
Why Xiaomi Antivirus Needs Cleaning
Xiaomi’s security system is based on the Avast or Tencent engine, which is integrated into the system application “Security”. APK-File and periodic storage checks: The algorithm is configured to remind the user of the “potential risks” or “junk files” as often as possible».
The frequency of deep-clean notifications depends on smartphone usage, and if you install applications from third-party sources or download large amounts of data, the system responds instantly, and it feels it is its duty to scan every new byte of information, which is redundant in today's environment.
⚠️ Warning: Complete removal of the system security component may lead to errors in the GetApps app store or the inability to install some banking programs.
Also, Memory Cleanup often works aggressively, shutting down applications you plan to use in a few minutes, resulting in rebooting programs and, paradoxically, more CPU power, and understanding the logic of how an antivirus works helps you configure it competently, keeping the balance between security and convenience.
It's also worth noting that the names of items may vary slightly from one version of the MIUI shell to another, but the logic remains the same: the system tends to control all processes in the background, and your job is to limit that control to what you really need to do.
Disabling automatic scanning during installation
The most annoying thing for many is that you have a scan screen every time you install a new app, and that behavior can be easily changed in the settings of the security component itself, so go to the main menu and find the app with the shield icon called Security.
When you start the app, look at the top right corner of the screen, and there's a gear setting button, and if you click on it, you'll be taken to the settings menu where you can control the behavior of the virus scanner, and you'll find "Scan before installation" or "Auto-scan" and you'll put the switch inactive.
Also in this section, the option "Check installed applications" is often found, and if you trust the source of software downloads, this feature can also be deactivated, which will speed up the installation process and eliminate unnecessary steps, but remember that basic verification of application signatures will still work at the system level.
For users who install apps through ADB or third-party stores, it’s helpful to be aware of hidden settings.Sometimes a standard switch isn’t enough and you need to disable the check through Google Play Protect, which can duplicate the features of Xiaomi’s built-in antivirus.
Set up notifications and pop-up windows
Even after disabling the auto scan, the system can continue to send push notifications with recommendations to “accelerate the phone” or “remove 500 MB of garbage.” To remove this visual noise, you need to change the notification settings of the Security app itself.
Go to Settings on your smartphone, then select the Application → All Apps section. Search Security (or Security) in the list. Click Notifications. Here you will see a long list of categories such as Memory Cleanup, Viruses, Optimization.
- 🔕 Turn off the “Recommendations” to remove ads and optimization tips.
- 🔕 Uncheck the box for "Scan Completed" if you don't need reports after each check.
- 🔕 Disable notifications on the lock screen so that outsiders do not see the status of the system.
- 🔕 Turn off the soundtrack for security events if it annoys you.
Once you do this, your smartphone will stop vibrating and glowing on trifles, the interface will become cleaner and attention will become more focused, and it is important not to overdo it and leave critical notifications on, for example, about blocking suspicious calls if you use this feature.
💡
If notifications keep popping up, try clearing the security app itself through the app settings menu, which will reset counters and temporary files that may have caused the bug.
Control of the deep memory cleaning function
Deep Clean analyzes large files, duplicate photos, and rarely used applications, and often runs automatically when free memory is low, and can be controlled through the Security menu itself.
Open the security app and select Clean up. Click on the settings icon (cogs) inside this section. Here you can set the warnings threshold. For example, you can prevent the system from alerting you if you have more than 2 GB of storage.
Also worth noting is the Memory Acceleration feature, which automatically closes the background processes. In modern versions of Android and MIUI, the system manages RAM efficiently, so manual or automatic killing of processes often harms multitasking.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Auto scanning | Off. | Acceleration of application installation |
| Notifications of cleaning | Off. | No pop-up windows |
| Clearing the cache | Manually. | Control over data to be deleted |
| Analysis of large files | On request. | Saving processor resources |
Regular manual cleaning once a month is more effective than constant background activity, which allows you to control which files are deleted, and automatic algorithms sometimes get it wrong and suggest removing important logs or cache of working applications.
Hiding icons and limiting work in the background
If you want to minimize the presence of antivirus, you can limit the operation of antivirus in the background, which will prevent the verification process from starting when you are not using your phone, but you need to do this carefully so as not to disrupt system stability.
Go to Settings → Apps → All Apps → Security. Select Autostart and make sure it’s off. Then go to Battery (or Energy Saving) for this app and select No Limits or Hard Limits if you want to completely disable background activity (not recommended for beginners).
☑️ Checklist for full deactivation
You can hide the Security icon from your desktop by deleting the shortcut. The app itself will stay in the system, but it won't horn your eyes. To do this, press the icon on your desktop and select Delete (this will only remove the shortcut, not the program).
For advanced users, it is possible to freeze the application via ADB. The pm disable-user --user 0 com.miui.securitycenter command completely disables the security center. Using this command can make it impossible to install applications from unknown sources without an additional crutch.
⚠️ Warning: Disconnecting system security services through ADB If you make an error, you may have an app store malfunction or you may not be able to download files from your browser.
Using third-party solutions instead of regular
Many users prefer to replace the standard antivirus with a third-party one, such as Kaspersky, Dr.Web or ESET. When installing third-party security software, Xiaomi’s system may conflict with it, requiring it to disable the built-in protection. Usually, when the first launch, the third-party antivirus will itself offer the necessary settings.
If you use a third-party file manager, such as Total Commander or MiXplorer, you may not need the "Security" feature to clean the disk, in which case you can completely ignore the system's suggestions to clean up the memory. Third-party tools often work more delicately and clearly.
It's important to understand the difference between an antivirus and an optimizer. Antivirus protects against malicious code, and an optimizer cleans garbage. Xiaomi combines these functions in one application. If you only need protection, you'd better use lightweight specialized applications, and clean up manually through storage settings.
