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.

    I found a solution that worked for me! the fake fbi alert only appeared for me when I tried to access the Internet. I tried restarting the phone and everything. I was panicking thinking I was going to have to take my phone to at&t for help but I decided to try using Google Chrome and it worked fine. I then went into my settings then apps and clicked internet and clicked force stop. reopened Internet and it was gone. checked for any suspicious apps and didn’t find any. I hope that was a permanent fix but it hasn’t come back on. hope this helps.

    Thank you SO MUCH! This guide really helped me out. Good heavens i really really freaked out when i saw that message on my screen…
    For future guidance to others: before this interpol message came, my mobile (LG Optimus II) gave me a white screen with “system update” – never seen it before. I managed to close it by opening another app from my recent app history.
    In the removal step of finding the name of the program: on my phone it was called “System update”, with a blue and white globe as logo. Rebooted and everything went back to normal.
    Again, thanks so much!

    thank you so much, and the person posted before me same thing to me! . this happened to my phone last night Good Thing I didnt pay my money to anyone!. I was like so freaking paranoid i couldnt sleep last night!. I thought i was going tojail. The fake FBI virus message on my android looked so real, like real legit. I read it 3 times.. and then 1 more time LOL. In the back of my mind i was like my parents are going to be so mad at me. At the bottom it read: fine is $500.00 to settle in 48hrs before you have a criminal case against you in 96 hours. You can go to your local 7-11 store or CVS etc. load cash onto PAYPAL account and type in code from card. You will get your $400.00 back in 30 days if you do not get in trouble.

    Thats when i was like Hahaha not uh! thats crazy!!. I told my mom like the next day she laughed at me. I told her it was scary. I learned a lesson and will definitely be telling people about the fake message. Dont send money online if it asks u to load money on a card. “Dont do it, Don’t do it.”- (Niki Minaj youtube clip , if anyone knows what im talking about lol.)

    Thank you so much for this! I was so scared that someone had hacked my phone to get me arrested. I dont understand how people could create something like that…the pop up looked so real (it was a new version and had official logos) it told me i had commited a number of offenses and even hacked into my camera and didplayed my photo on the page…I had hundreds of thoughts as to what I would do..I knew I was innocent but in I was panicking afraid of how the hell i would tell my parents I needed $500 or that I had been scammed and would have to go to court. I was so stressed out and upset that I thought about destroying my phone or even suicide simply because I thought the police would be at my door in a few hours and i couldnt mentally handle that thought.The only reason I didn’t do anything rash was because it told me I had to pay with a very specific type of card… This site saved me and got rid of the virus but I have anxiety problems and still worry about checking my mail and people knocking on my door afraid that police or investigators have come to accuse me of breaking the law and arrest me because I didn’t pay and the hackers gave out false information and I will get into trouble for it….I know it makes no sense but that’s how bad this experience scared me. It did teach me a very valuable lesson to never click on adds online though…..I know that eventually I will get over this anxiety but it will take a while but I definitely plan on donating thank you again!!!!!
