Nowadays many developers provide free applications for the Android platform, but the cost of the Free application are the Ads (advertisements) which are displayed while using your Android device. By doing that, the developer offers you his application for free, but he gets an income
from the Ads publisher that helps keep him active in business and productivity. But applications that are offered for free are not always trustworthy and may contain malicious code in order to always display annoying Ads in every application you open in your Android device or to compromise your privacy. For that reason, a good precaution is to periodically check your Android device for malicious software, to remove all unwanted or unrecognized apps and to clear the browser's history and cache (Temporary files).
In this Android Virus Removal Guide tutorial I will show you how to scan and remove malicious software (e.g. Adware, Ransomware, Screen lockers, etc.) from your Android device, plus some protection tools and precautions to keep your device clean and protected.
How to protect your Android Device and yourself from Malware.
- Avoid the installation of applications that come from unknown sources. To take care of that uncheck the "Unknown sources" option found under Settings > Security > Device Administration.
- Before downloading an application, always read the reviews and rating.
- Always check the permissions and locations that an application wants to access when downloading.
- Always keep Android up to date.
How to Remove Adware & Malware Apps from Android (Including FBI Police virus).
ATTENTION: If your Android device is heavily infected with malware (e.g. if it is blocked from a ransomware virus or it freezes), then you have to enter Android in Safe Mode before performing the steps below. The instructions on how to boot Android in Safe Mode can be found in this article: How to Boot your Android device in Safe Mode.
- Notices for devices infected with the Android FBI-Police (or other) Screen Locker virus:
1. Keep in mind that in some cases the Android FBI (FBILock-APolice) scam message virus cannot be removed from some devices by using the steps described in this article. In these cases – unfortunately – the only way to get your Android device back to normal operation is to reset your phone to factory settings (factory defaults). Before doing that, first ensure that you don't have any important files on your device because all your files and settings will be erased.
2. Before performing a factory reset, give it a try and perform every step of this article. If you cannot perform a step, then continue to the next one.
3. For Amazon Kindle owners: The only way (as I know) to remove the FBI-Police screen-locker virus is to reset your KINDLE device to factory defaults settings (in Safe Mode).
Step 1. Stop all recently used applications on your Android device.
First of all, you have to close all recently used (open) apps. Depending on your phone's model, the way to do that varies. For example:
- On an HTC One: While on home screen, tap the ‘Home’ key twice. Then, tap an application and swipe up to close it. Repeat this, for all open Apps.
- On an LG G3: While on home screen, tap the two stacked boxes next to the home button. Then press the “Clear All” button to remove them all.
- On a Samsung Galaxy S3 or S4: While on home screen press & hold down the “Home” menu button on your device. Now, press the ‘Close All’ icon on the bottom right corner to close all open apps (or tap an application and swipe left or right until the application's thumbnail disappears. Do the same for all running applications).
- On a Nexus 4 or Galaxy Nexus, press the multitasking button. Then, tap an application and swipe left (or right) to close it. Repeat this, for all open Apps.
- On XIAOMI phones press the Recent items menu and then tap the X symbol on screen.
- On HUAWEI phone press the button and then tap the recycle binto close all running apps.
* Note: If you don’t know how to close the recently used apps, just restart your phone and then continue to the next step.

Now, proceed and close all the applications that are still running in the background (e.g. Internet Explorer, Chrome, etc.).

2. On XIAOMI phones, go to Installed apps.
4. While in Application Manager, swipe to ‘Running’ tab to display all running applications. *
5. From ‘Running’ applications list, tap to open and then stop (Force Stop):

6. When finished, go back to to Application Manager's main screen and continue to the next step.
Step 3: Uninstall all the recently downloaded or unrecognized apps from your Android device.

* Note: ON XIAOMI phones, tap the Uninstall button on Installed apps menu.
2. Review all the installed applications and uninstall:*

2. Tap the app that you cannot uninstall.
3. Choose "Deactivate" > “OK” and immediately shutdown (or remove the battery from) your device.
