Faced with a situation where only the logo is displayed on the screen of your smartphone or tablet Kaspersky and nothing else, the user may experience reasonable concern. This condition, often called "stuck on screen" or "bootloop" by an antivirus, blocks access to the main interface of the operating system Android. In fact, the device turns into a “brick”, since a security application has seized control of the screen and does not allow the initialization process to be completed. Such a problem is not a critical hardware failure, but requires immediate intervention to restore the functionality of the gadget.
The reasons for such a failure can vary from a simple software version conflict to critical errors in the virus signature database. Sometimes the situation is aggravated by the fact that the antivirus activates the “Anti-Theft” or “Device Blocking” mode when security sensors falsely trigger. In this material, we will analyze in detail the mechanics of the error when Kaspersky occupies the entire screen, and we will propose a step-by-step algorithm of actions to regain control of the smartphone without losing personal data.
Failure mechanics: why the antivirus blocks the system
To understand how to fix the problem, you need to understand why the application Kaspersky Internet Security or Kaspersky Endpoint Security behaves in a similar way. Antivirus apps on the platform Android have expanded access rights, including the right to overlay the interface on top of other applications (SYSTEM_ALERT_WINDOW). This is necessary to display real-time virus alerts. However, if the code fails or the cache is damaged, this mechanism can go into loop, creating an endless loop of drawing the initial screen.
The database update process is often the culprit. If a device loses connection to the network or is forced to reboot while downloading new threat signatures, the database may end up in an inconsistent state. The next time you start it antivirus engine tries to read the damaged file, freezes and displays only a static splash screen. This is a protective mechanism that prevents working with incorrect data, but is poorly implemented in terms of user experience.
⚠️ Attention: Do not try to endlessly reboot the device in the usual way. If the problem is caused by corrupted antivirus system files, a cycle of reboots will only make the situation worse, draining the battery and heating up the processor unnecessarily.
Another common cause is a conflict with other applications that have device administrator rights. If you recently installed a new launcher, task manager, or other security software, they may have hijacked display priority. In rare cases, a failure is caused by the operating system itself Android after a major update, when the APIs used by the antivirus to display its windows are changed.
Before starting active recovery actions, if possible, connect the device to a charger. The reset and reboot processes in emergency mode consume a significant amount of energy.
Primary diagnostics and safe mode
The first step in troubleshooting should be to enter Safe Mode (Safe Mode). In this mode, the operating system Android loads only with basic system applications, ignoring all third-party software, including Kaspersky. This allows you to access the settings and remove or disable the problematic application. The login method may differ depending on the manufacturer of your smartphone (Samsung, Xiaomi, Pixel etc.).
Usually the procedure is as follows: hold down the power button until the shutdown menu appears. Then press and hold your finger on the Power Off or Restart option on the screen. After a few seconds, the system will ask for confirmation to enter safe mode. Confirm the action. If the touch screen does not respond due to the screen saver blocking, use a combination of physical buttons: most often this is holding the volume down button while the device boots after turning off.
- 📱 Hold the button
Volume Downimmediately after the manufacturer logo appears when turning on. - 🔄 Try the combination
Power+Volume Downfor 10-15 seconds to force a reboot and then enter the mode. - 🔍 On some models Samsung You must press
Side buttonandVolume Downat the same time when loading.
If you managed to successfully boot into safe mode, you will see the corresponding message in the corner of the screen. In this state, the icon Kaspersky will be translucent or inactive. This is a signal that the problem really lies in the application, and not in the phone’s firmware. Now you have full access to the menu Settings → Applications.
Removing and clearing antivirus data
When you are in safe mode or if the system still gives access to the menu, you must force stop and clear application data. Simply deleting a app may not work if it has rights device administrator. First you need to remove these privileges. Go to the section Settings → Security → Device administrators (the path may differ slightly depending on the version Android).
Find in the list Kaspersky and uncheck The system will ask for confirmation - agree. After that, return to the application menu, find the antivirus and select the “Storage” or “Memory” item. Here it is critical to press the button "Clear". data" ". This will delete all local settings, signature databases and temporary files that could cause the failure. "Clear cache" This will remove any local settings, signature databases, and temporary files that may have caused the crash.
| Action | Impact on data | Requirement of admin rights |
|---|---|---|
| Forced stop | Temporary termination process | Not required |
| Clearing cache | Deleting temporary files | Not required |
| Clearing data | Resetting settings to factory settings (internal applications) | Not required |
| Removing the application | Complete removal of the app | Removal of rights required |
After clearing the data, try rebooting the device in normal mode If the problem was caused by corruption of the configuration. file, the smartphone should boot normally, and the antivirus will offer to configure it again. If the application freezes on the splash screen again immediately after launch, the only solution is complete deletion.
⚠️ Attention: Cleaning the antivirus data will lead to the loss of scan history and quarantine files. Make sure that important documents that you did not manage to restore before resetting are not stored in quarantine.
☑️ Algorithm for completely unblocking
Using ADB for uninstallation
In situations where the touch screen is completely blocked by the screen saver Kaspersky and even safe mode does not help to access the settings, it comes to the rescue tool ADB (Android Debug Bridge). This method requires a computer (Windows, macOS or Linux) and a USB cable. It is important that USB debugging is previously enabled on your smartphone. If this function has been activated, you can delete the application remotely, bypassing the GUI.
Connect your phone to the computer and open the command line or terminal in the folder with the installed platform. tools. Enter the command to check the connection:
adb devicesIf the device is listed with status device, you can proceed to uninstall. You will need to know the exact name of the application package. For Kaspersky this is usually com.kms.free or com.kms.android. command for forced uninstallation:
adb shell pm uninstall -k --user 0 com.kms.freeThis command will remove the application for the current user, which is essentially equivalent to a complete removal. After executing the command, restart the smartphone. The screensaver should disappear, since the executable code of the application will be removed from the system.
What to do if ADB does not see the device?
If the 'adb devices' command shows 'unauthorized', look at the phone screen. Perhaps a window has popped up asking for debugging permission, which is hidden under the splash screen. Try blind clicking in the center of the screen or using your mouse via OTG cable to confirm. If debugging has never been enabled, this method, unfortunately, will not work.
Specifics of corporate versions and MDM
Special attention is paid to cases when the problem occurs on corporate devices with Kaspersky Endpoint Securityinstalled. These versions are often managed through an admin console and may have strict security policies that prevent the user from disabling security or uninstalling the application. In this mode, the screen saver can be an element of the Kiosk policy or blocking the device if the rules are violated.
If you see a message that the device is blocked by the administrator, independent reset actions may not be possible without a special unlock code. Attempts to bypass protection through safe mode may be blocked at the bootloader level. In such scenarios, standard removal methods will not work, since the application is protected from uninstallation by rights Device Owner.
- 🏢 Contact your company's IT department for an unlock code or instructions.
- 🔐 Do not attempt to reset the device to factory settings if it has important work data on it - this may lead to permanent loss and locking of it account.
- 📩 Check your corporate email for notifications about device blocking due to suspicious activity.
For ordinary home users, this problem is not relevant, but owners of work phones should remember that in the corporate segment the rules of the game are dictated by the control server, not the user.
Corporate versions antiviruses often have deletion protection, which cannot be bypassed without domain administrator rights or a special unlock code.
Radical measures: hard reset
If none of the above methods helped, and the phone still shows only the logo Kaspersky, the last option remains - a full reset to factory settings (Hard Reset). This procedure will delete absolutely all data from the device’s internal memory: photos, contacts, messages and applications. Use this method only as a last resort.
To perform a reset, you must enter the menu Recovery. Turn off your phone completely. Then hold down the combination of buttons specific to your model (most often Power + Volume Up or Power + Volume Down). Hold them down until the logo or recovery menu appears. In the menu controlled by the volume buttons, select the item Wipe data/factory reset and confirm the action with the power button.
⚠️ Attention: After the reset, protection will work on modern devices FRP (Factory Reset Protection). You will definitely need to enter the username and password for the Google account that was synchronized with the phone before the reset. Make sure you remember this data.
After completing the cleaning process, select item Reboot system now. The device will reboot as new. The antivirus will be removed along with all other applications. You can set up your phone again and, if desired, install the latest version from the official store to check if the error occurs again. After a hard reset and initial setup, do not restore all applications at once from a backup. Install the antivirus first and check its operation on a “clean” system to eliminate conflicts with other software. Kaspersky from the official store Google Playto check if the error occurs again.
After a hard reset and initial setup, do not restore all applications from backup at once. Install the antivirus first and check its operation on a “clean” system to avoid conflicts with other software.
Prevention and conclusions
The problem of freezing on the screensaver Kaspersky is a rare but possible scenario, which is most often associated with software conflicts or damage to update files. To minimize risks in the future, it is recommended to promptly update the application itself and the operating system Android. Developers regularly release patches that correct such vulnerabilities.
Avoid installing antiviruses from unverified sources and third-party APK files. The official version from Google Play passes additional testing for compatibility. Also, do not abuse the “acceleration” and “cleaning” functions, which are often unnecessary on modern versions Android and can interfere with the operation of system security processes.
In most cases, the problem can be solved through safe mode and data clearing, without resorting to a full reset. The main thing is to remain calm and act consistently, understanding that your data is most likely safe, just that access to it is temporarily limited by a software glitch.
Is it possible to recover data after a Hard Reset?
Restoring data after a full reset to factory settings is extremely difficult and in most cases impossible without professional equipment. If you have not configured automatic backup to the cloud (Google Photos, Google Drive), the data is considered lost.
Why does an antivirus require administrator rights?
An antivirus needs device administrator rights to perform critical functions: remotely blocking a phone if it is stolen (Anti-Theft), forcing the removal of malware, and protecting security settings from being changed by viruses.
Does this problem affect the warranty of the smartphone?
No, software failures of applications, including antiviruses, are not grounds for denial of warranty service if you did not try to get root access or did not reflash the device using unofficial methods in the process of solving the problem.
What to do if the phone is blocked by an antivirus and is not included in the safe one mode?
If safe mode is not available, try connecting a USB mouse via an OTG adapter. Sometimes this allows you to bypass the sensor freezing and get to the settings. If this does not help, the only option left is to use ADB (with debugging enabled) or a full reset via Recovery.
