How to Remove a Virus from a Xiaomi Phone: The Complete Guide

Owners of Xiaomi, Redmi and Poco smartphones often face intrusive advertising or strange behavior of the system, mistakenly believing that the device is infected with a virus. In fact, the Android operating system in conjunction with the MIUI shell has powerful built-in protection mechanisms. However, installing applications from third-party sources or accidentally clicking on dangerous links can lead to the penetration of malicious code. This can be both a classic Trojan that steals data and aggressive adware that causes pop-ups.

The symptoms of infection are often similar: the phone starts to heat up, the battery runs out faster than usual, and unfamiliar icons appear in the list of applications. Sometimes the virus disguises itself as a system process or completely hides its icon, running in the background, in which case the user must act quickly and consistently to prevent leakage of personal information or locking the device.

In this article, we will look at proven methods to remove the virus from the shaomi, ranging from simple checks with built-in antivirus to a complete reset. It is important to understand that in most cases, the problem is solved without losing data if you notice a threat in time. It is critical not to enter bank card details on suspicious sites until the gadget is completely cleaned.

Primary diagnosis and signs of infection

Before you start taking any drastic measures, it's important to make sure that the problem is really caused by malware, not by a system failure or hardware malfunction. The main indicator is the behavior of the interface and resource consumption. If you notice that RAM is constantly busy, although few applications are running, this is an alarm bell, and you should also pay attention to traffic: viruses often transmit data to remote servers.

Advertising banners that appear on the desktop or when you unlock the screen are a sure sign of the presence of adware. Often such programs are disguised as useful utilities: flashlights, memory cleaners or scanners. QR-They may not have icons on the menu, but they're active in the background.

• 📉 A sharp drop in autonomy and fast battery discharge even in standby mode.
• 📢 Spontaneous opening of browsers, tabs with advertising or installation of unknown applications.
• 📈 Unreasonable consumption of mobile traffic and heating the case in simple tasks.
• 📵 Blocking access to settings or not being able to delete a suspicious file.

You can use the built-in tools to diagnose accurately. Go to Security → Antivirus and run scans. Although the built-in engine doesn't always find complex threats, it does effectively detect known malware signatures. If the scanner is silent but the symptoms are present, you will need to manually analyze the installed programs.

⚠️ Warning: If you see a message on the screen about a locking of the phone by the police or a request to transfer money to unlock, do not follow the instructions. This is phishing, and the actual locking of the device at the hardware level is impossible in this way.

Using built-in antivirus and cleaning the cache

The first step in combating threats should be to use the regular Security app, which Xiaomi has integrated into the MIUI shell an engine from Avast or AVL, which is regularly updated, the first line of defense that can detect and neutralize most known threats without installing third-party software.

To run the check, open the application and select Antivirus. The system will automatically check the installed applications, files and system partitions. If a threat is found, you will be prompted to remove it or quarantine it. In some cases, you may need to update antivirus databases through the scanner settings menu.

In parallel with virus testing, it is recommended to clear browser cache and system debris. Malware scripts are often stored in temporary browser files. Go to Settings → Applications → All applications, find your browser (Chrome, Mi Browser) and choose Clear → Clear Everything. This will delete temporary files, cookies and history where the code may be hiding.

Also check application permissions. Go to Settings → Privacy Protection → Permission Manager. Pay attention to Autostart, Display on top of other applications and Access to Files. If a simple calculator or voice recorder requires access to contacts and SMS is a clear sign of malicious activity, and such an application should be removed immediately.

Analysis of the application list and removal of malware

If the scanner doesn't work, you'll have to do a manual audit, and many Android viruses are masked, they may be called System Service, Update, or they may not have a name at all, and to find them, you need to look carefully at the list of all the software you've installed.

Go to Settings → Applications → All apps. Scroll through the list carefully. Look for apps without an icon (empty white field) or with suspicious names that you haven't exactly installed. Often, these programs are located at the bottom or at the top of the list to get lost among system processes.

When you try to remove the malware may resist: the Remove button will be inactive or the application will be restored immediately, in which case you must deprive it of its administrator rights. Go to Settings → Passwords and Security → Privacy → Special Access → Device Administrator Applications. If you see an unknown program there, uncheck and confirm the deactivation of the rights. Only then it can be removed in the standard way.

Pay special attention to applications that have permission to "Map on top of other windows"; this mechanism allows viruses to overlap the interface and display ads. Search by settings, type "above other applications" and disable this feature for any suspicious or unnecessary programs.

Cleaning in Safe Mode (Safe Mode)

If the virus is not removed or the phone is extremely unstable, you need to go to Safe Mode, in which the operating system only loads with system applications, and all third-party software, including viruses, is blocked, which allows you to safely remove the malicious program that normally prevents this from happening.

To enter safe mode on most Xiaomi smartphones, you need to press the power button and then press and hold your finger on the "Stop" item on the screen until you prompt to go to safe mode. On some Android 11-13 models, you just need to press the off button and volume down when you boot, but the method with the screen menu works more often.

While in Safe Mode (there will be a corresponding label in the corner of the screen), re-enter the app list. Now you can safely remove the virus as it is not running. Find a suspicious app and click Delete. Once successfully deleted, just restart the phone in the usual way to return to normal mode.

⚠️ Note: Some functions do not work in Safe Mode, for example, NFC It's okay, don't try to reset your settings in this mode unless absolutely necessary, just delete the malicious file.

Resetting to factory settings (Hard Reset)

If none of the above methods have helped get rid of the virus, the last and most radical but effective way is a complete reset (Hard Reset), which completely cleans the internal memory of the phone, returning it to the state of “out of the box”. All your data, photos, contacts and applications will be deleted, so first back up important information to the cloud or to your computer.

You can reset through the settings menu if the phone is turned on. Go to Settings → About Phone → Reset. Select Erase All Data. The system will alert you to the loss of information and ask you to enter an unlock password or password from your Google account for confirmation.
