Remove Android Lock Screen Ransomware [Virus Removal]

By Stelian6 min read

If you are unable to access your Android phone or tablet and are seeing a lock screen message stating that your device has been blocked, it is likely that your device has been infected with a malicious app.
These types of apps can be downloaded from malicious websites or legitimate websites that have been hacked and offer a “video player” or other seemingly useful app for download. The infection may also be downloaded manually if the user is tricked into believing they are installing a genuine update for software such as Adobe Flash Player.

What is the Android lock screen Ransomware?

Ransomware has evolved in recent years and the Windows operating system is not the only one who can get infected with this type of malware. With Android overwhelmingly the most common operating system for mobile devices, ransomware specially made for phones, tablets, and more is also on the rise.

The malicious ransomware apps will lock you out of your Android device and applications, so whenever you try to unlock or use your smartphone, it will display instead a lock screen asking you to pay a ransom in vouchers or cryptocurrency (Bitcoin, Monero, Dash). The malware’s authors prefer these payment services because transactions made through them cannot be reversed and are hard to trace.

Unlike Windows devices, the good news is that the infection doesn’t encrypt any of your data on your Android, and it merely locks your device with a popover browser window that quickly reappears if you try to get clear of it. The bad news is that the continually reappearing pop-over window makes it as good as impossible to get into the Settings menu to remove the malware.
Even rebooting won’t help as the malware kicks back in early in the process of restarting. A factory reset will get rid of it, but that also removes all your other installed apps and stored data.

The messages on this Android lock screen Ransomware are for the most part a scam, and you should ignore any alerts that this malicious app might generate.
Under no circumstance should you send any vouchers or cryptocurrency to these cyber criminals, and if you have, you can request a refund, stating that you are the victim of the malware.

Remove Android Lock Screen Ransomware

This page is a comprehensive guide that will remove the malicious app from your Android phone. Please perform all the steps in the correct order. If you have any questions or doubt at any point, STOP and ask for our assistance.

To remove malware from Android, follow these steps:

STEP 1: Start Android in Safe Mode

In this first step, we will start your phone in Safe Mode to prevent malicious apps from interfering with the next steps. We’re using Safe mode because it starts Android in a basic state, with only the factory apps and settings.

  1. Long press the power button.

    Long press the hardware power button (located on the side of your phone) until the power off menu appears.

  2. Tap and hold on “Power off”.

    When the power off menu appears, tap and hold on the “Power off” button on your screen until you get the “Safe mode” option.
    Long press the hardware power button on your Android phone until the power off menu appears

  3. Tap on “Safe Mode”.

    When the “Safe mode” option appears on your screen, tap on it to enter safe mode.
    Long press power off to enter Safe Mode

  4. Your phone is in Safe Mode.

    Your Android phone will now restart and enter into safe mode. When your phone is in safe mode, you’ll see the “Safe Mode” text at the bottom left corner of your phone. You can now continue with the next step.
    Safe Mode Android
    If you can’t find a safe mode on your phone, activate Airplane mode instead, to cut your device off from any networks.

STEP 2: Remove malicious device admin

In this second step, we will check the phone to see if there are any malicious apps with administrator privileges installed on your phone.

The administrator privileges are used by apps to perform legitimate tasks such as device management or for antivirus apps to do a remote wipe. Unfortunately, these elevated privileges are also being used by malicious apps to prevent victims from removing the malicious app from their phone.

  1. Open the “Settings” menu.

    Tap on the “Settings” app from your phone menu or home screen.
    Settings app in Android

  2. Go to “Device admin apps”.

    When the “Settings” menu opens, if you’re using a newer version of Android or a Samsung phone, tap on “Biometrics and Security“, then tap on “Other Security Settings” and then on “Device admin apps“.Device admin apps

    However, because there are phones with different versions of Android the “Device admins apps” settings may be in a different menu, so below we’ve listed other common ways to reach the “Device admin apps” options:

    • Security > Device admin apps
    • Security & privacy > Device admin apps
    • Security > Device Administrators
    • Lock Screen and Security > Other Security Settings > Phone Administrators.

    If you’re having trouble finding the “Device admin apps” settings, you can use your phone’s built-in search function to search through the Settings.

  3. Disable administrator privileges for the malicious app.

    Once you’ve accessed the list of device admin apps, disable admin rights by tapping the option to the right of the app. This will remove the checkmark or toggle the button to the off position. Now you can delete the app normally as seen in the below step. On some phones, you can tap the app right there in the admin apps list and then use the Uninstall app link to remove it immediately.

    Disable admin rights for the malicious app - Android
    If there is no malicious app with administrator privileges on your phone, then you can continue with the next step from this guide.

STEP 3: Uninstall the malicious apps

In this third step, while the phone is still in Safe Mode, we will check if any malicious apps are installed on your device. Sometimes browser hijackers or adware apps can have usable Uninstall entries that can be used to remove these apps.

  1. Open the “Settings” menu.

    Tap on the “Settings” app from your phone menu or home screen.
    Settings app in Android

  2. Tap on “Apps”.

    When the “Settings” menu opens, tap on “Apps” (or “App Manager”) to see all the installed applications on your phone.
    Tap on Apps

  3. Find the malicious app.

    The “Apps” screen will be displayed with a list of all the applications that are installed on your phone. Scroll through the list until you find the malicious app.
    Look out for any suspicious app that could be behind all the drama – anything you don’t remember downloading or that doesn’t sound like a genuine program. Most often, cyber criminals hide malware inside video or photo editing apps, weather apps, and camera apps.

    Here are some known malicious apps: ES File Explorer, Xender, Amber Weather Widget, GO Weather Forecast & Widgets, Kitty Play, Touchpal, Z Camera.

    The malicious program will most likely have a different name on your phone. If you cannot find any malicious app on your device, you can exit “Safe mode” (as seen below) and continue with the next step from this guide.

    Search trough the Apps list for the malicious app

  4. Uninstall the malicious app

    When you find a suspicious or malicious app, tap on it to uninstall it. This won’t start the app but will open up the app details screen. If the app is currently running press the “Force stop” button, then tap on “Uninstall”.
    Uninstall malicious app from Android

    A confirmation dialog should be displayed to confirm you want to uninstall the app, tap on “OK” to remove the malicious app from your phone.

    Confirm uninstall app from Android phone

  5. Exit “Safe mode”.

    Now that we’ve removed the malicious apps from your phone, we can exit “Safe mode”. To do this, hold the power button on your device until you get the power off menu, then select the restart option from the menu.

    Restart your phone to exit Safe Mode - Android

    Your phone will now be rebooted and exit from the safe mode and boot into the normal mode.

It wouldn’t let me do anything with my phone. After I read your article I removed it so you helped me a lot. If I could thank you personally, I would.

But my phone only showed power off and restart and it did not show select safe mode, although I kept holding the power button as it is explained here So I installed remotely avast ransomware remover from google play. It was installed but as soon as it wants to start scanning my phone the fake police warning comes up and avast stops at 7% and disappears. I switched my phone off and off several time and I waited each time but no use. My android is 4.2.2.

      Hello,
      Please try again to start into Safe Mode. Turn off the gadget (hold the power button, tap “Power off” and then tap OK). Wait a few seconds and then turn the gadget back on.
      When you see the Samsung logo, press and hold the Volume Down button until Safe Mode shows up .
      Next go and uninstall any malicious app (recently known malicious app: System Update, System Malware, Security Update or Security Helper.

    Hi. My son got the FBI shit in a danish translation today on his Samsung S3 mini, perhaps when he was installing “Instagram” from Google Play Store. It was located on his homescreen and called “System malware” and with a green avatar like the Android thing. He tried to open it out of curiosity. Nothing happen until an hour later when the FBI shit turned up. He got freaked because he hasnt done anything wrong. I`ve seen it before on a computer, so I knew it was a virus. Thanks to the tricks on this side, we got rit off it again in an hour or so. Thanks for your help. Kind regards, Lars Christiansen Denmark

    In my case it was an android Update causing the drama.

    Thank you, great advice! Finding the malicious app was a bit tricky but after that piece of cake :) Just to mention, Avast mobile security was installed but didn’t protect the phone. After removing the web shield was not on, hard to say if it was turned off even before the infection.

    I followed the steps but i can not seem to detect the possible app with the virus. The only one which seems fishy is “System Update” with an android symbol as the icon. When i try to uninstall it, it does not allow me to “force stop” or “uninstall”. Could anyone give me possible solutions? Thanks

      In reply to Henry

      Actually found out the reason as to why i could not unistall the virus app. There is a setting on the “virus app” (in my case it was called “System Update”) called “device administrative privileges” where you can not “force stop” or “uninstall” so easily. As it is marked as a privilege app, all you have to do is to unmark it. From “Settings” you simply go to “Security” and from there open “Device administrators” or “Phone administrators”. You should be able to see the suspected “virus app” with a ticked box right nex to it. Untick the box, and simply resume to the uninstallation of the application. I hope this helps because it definitely fixed my problem
