Owners of Xiaomi, Redmi and Poco smartphones often face a frightening notification: a red window pops up in the security center saying, “Find 1 threat, eliminate it,” which causes panic, especially among inexperienced users who fear for the safety of their bank data and personal photos. However, in most cases, the security system of MIUI or HyperOS does not respond to a real virus, but to potentially unwanted actions of applications or the presence of cache, which the algorithms considered suspicious.
A system scanner that runs on Avast or Antiy engines does a deep background analysis of the file system, and when it detects an application with permissions that are outside the standard, or a program that does not have a digital signature on the Google Play store, it labels it as a threat. It's important to understand that "threat" in Xiaomi terminology is a broad term that includes not only Trojans, but also just junk files or aggressive advertising.
The next step depends on the source of the problem (APK-In the normal situation, it is enough to perform the standard cleaning procedure offered by the system interface. Ignoring these notifications is not worth it, since the constant presence of background processes can reduce the autonomy of the device and quickly drain the battery.
Analysis of the source of notification and types of threats
Before you click the "Eliminate" button, you need to understand what caused the antivirus reaction. Xiaomi's security system classifies risks by risk levels. Most often, the category "Risk" or "Unwanted Software" is the presence of modules in the application to display ads or collect statistics, rather than malicious code to steal passwords.
Real viruses, such as encryption Trojans or spyware, are much rarer and usually get to the device after installing hacked versions of paid games or programs. APK-files, but also behavioral patterns. SMS to a paid number or access contacts without the user’s knowledge, it will be blocked.
⚠️ Note: If the notification appears immediately after installing a particular application from an unknown source, the probability that it is a real virus is more than 80.
There is also the concept of “false positive”: This occurs when a system analyzer mistakenly tags a legitimate application because of the similarity of its code to known viruses or because of the use of non-standard methods of data encryption, in which case the system may suggest removing a completely secure program.
Step-by-step instructions: how to eliminate the threat by regular means
To remove the detected threat, you do not need to install third-party software, since the powerful Security tool is already built into the MIUI shell. Open the application with the green shield icon on the home screen or in the Tools folder. Go to the Antivirus section and click the large Check button.
Once the scan is complete, the system will give you a list of problems. If 1 threat is found, click on the "Eliminate" or "Clean" button. The system will prompt you to delete the malicious file or restrict the rights of the suspicious application. Confirm the action and the file will be quarantined or deleted irrevocably.
☑️ Algorithm of actions in the detection of a virus
In some cases, automatic deletion can be blocked if the malicious application has device administrator rights. Then you will need to manually go to the settings, find the password and security section → Privacy → Special access → Access to use and disable suspicious items. Only then the antivirus will be able to complete the cleanup.
💡
Before removing the virus, take a screenshot of the threat name, which will help you find information about the specific virus on the Internet, if standard removal does not help.
Manually remove malicious applications through settings
If the built-in scanner can’t remove the threat or it reappears after cleaning, you need to manually remove it. Go to Settings → Applications → All applications. Carefully review the list for programs with strange names, no icons or a name consisting of a set of characters.
Often viruses are disguised as system processes, called Update Service, Wi-Fi Tool, or Flash Player. If you see an application that you didn't install, or it was installed on the date the problem occurred, it's a candidate for removal. Click on it and select Delete.
In situations where the delete button is inactive, the application has administrator rights. To select them, go to Settings → Passwords and Security → Privacy → Special Access → Applications with administrator rights. Uncheck the suspicious program, then return to the application menu and delete it in the standard way.
| Type of threat | Symptoms | Deleting method |
|---|---|---|
| Advertising virus (Adware) | Pop-up advertising on the desktop | Removal through application settings |
| Trojan | Write-offs, data theft | Safe mode + Antivirus |
| Miner | High heat, system brakes. | Complete reset or manual removal |
| False PRO | No external symptoms | Ignoring or adding to exceptions |
Use of safe loading mode
If the virus blocks your smartphone, prevents you from opening settings, or constantly displays advertising windows, you need to go to safe mode. In this mode, only system applications are loaded, which allows you to safely remove the malicious file. To enter, press the turn off button on the screen, and when the "Stop" icon appears, press and hold it for a few seconds before the suggestion to go to safe mode appears.
While in Safe Mode, you won’t see any third-party icons on your desktop. Go to your app settings and uninstall all newly installed programs. It’s also a good idea to clear your browser cache, as threats often get through ad scripts in Chrome or MIUI Browser.
Once you remove any suspicious items, just restart the device in the normal way, the smartphone will return to normal and the system should work steadily, and if the problem persists, then the virus could have penetrated deeper into the system, and a more radical approach will be required.
What to do if the virus is not removed?
Checking through Google Play Protect and third-party scanners
Even if you use Xiaomi, Google Play Protect’s built-in protection remains an active background security layer. It checks apps when installed and scans the device periodically. To run the manual check, open the Google Play Store, click on the profile icon and select Play Protection.
If Xiaomi's built-in antivirus is silent, but you suspect something is wrong, you can use one-time scanners from well-known vendors like Malwarebytes or Dr.Web Light. These applications do not require permanent rights and work on a found-delete principle. They often have more recent signature databases for new threats.
However, you should not install multiple persistent antiviruses at the same time, which will lead to background conflict and a serious performance loss, and use third-party software only for a one-time deep check, after which it can be removed.
⚠️ Warning: Do not install apps with names like Clear Master, Super Antivirus from unverified sources, and often these programs are the carriers of advertising modules and create the appearance of activity to impose a paid subscription.
Radical measures: reset to factory settings
If none of the methods helped get rid of the “Find 1 threat” notification and the behavior of the phone remains unstable, the last reliable way is a full reset.
Before starting the procedure, be sure to back up important contacts and photos to Google’s cloud or computer. Remember that after resetting, all apps and settings will be deleted. To start the reset, go to Settings → About Phone → Settings Reset → Erase all data.
During the reset process, the system may ask for a password from your Google account or Mi Account to confirm ownership of the device (protection against theft).
💡
A complete reset is the only way to guarantee the removal of viruses that have infiltrated the system partition, but it requires the prior storage of personal data.
Prevention: How to avoid infection in the future
To avoid any threat reporting, you should follow digital hygiene guidelines, first of all, stop installing applications from unknown sources. MIUI There is a “Device Protection” function that blocks the installation. APK-files from the browser or messengers.
Update your operating system regularly. In Security Patch updates, Xiaomi closes vulnerabilities that viruses can penetrate your phone, and perform a preventive scan with built-in antivirus once a month.
Be careful with permissions. If a simple flashlight or calculator requires access to contacts, SMS and location is a clear sign of fraud.
