Android is the most popular mobile operating system, thanks to its open source nature and millions of downloadable Apps across Play Store and other Resources. Presently there are more than 2 Billion monthly active Android users across the globe which makes around 90% of the smartphone industry. Also, according to the report, 95 % of every new smartphone runs on Android.
Given such a large majority of the user base and also its open source policy. Android is very much prone to be attacked by virus and other malware. According to a report by an independent security firm by Mike Rogan, about 98% software malware is shared by Android OS. This shows how vulnerable Android smartphones are to be infected by the virus. Google regularly releases security patches in software updates to protect Android from any such threat.
Many times we download or share the apps from non-reliable sources in a quest of getting a paid version of the app for free or to download a particular app which is not available in Play Store. The apps which are not downloaded from reliable sources like Google Play Store or Amazon Store could be potentially harmful and malicious for your phone and also to you as a user by harassing the privacy.

If not your interest based Ads then don’t click on any of the links. The links may redirect you some third party sites which resemble the original one and deceive you for your Personal info or account credentials.

Remove Virus From Android Mobile
In most cases, the virus is injected into the device from apps downloaded from unknown sources or in some cases from Play Store. So, it is better to check for such vulnerable apps with Trojan virus.
#1. Reboot in SafeMode to Check for Malicious Apps
To Remove the Harmful Apps we can try a boot in safe mode. In safe mode, only default apps which were present at the time of unboxing are present and downloaded apps are not available.
For Android 4.4 and less
- Turn off your device
- While powering on press and hold volume down key
- Your device will be in Safe Mode (A transparent logo of Safe Mode will appear on screen).
For Android 5.0 and more
- Long press on power key as you do for turning off your device.
- Tap and press on power off option.
- You will see the option of Reboot to safe mode. Tap Ok to enter the safe mode.
In safe mode check for device functioning, if the device is working normally then any 3rd party downloaded app is causing the issue.
Just reboot the device to come back to normal mode and uninstall any or all the suspicious 3rd party apps and check for normal working. The device will get rid of any sort of virus or malware.
#2. Remove Administrator Access to Uninstall Harmful Apps
Knowingly or unknowingly you may have granted any dangerous app Device administration access. The app may now interfere with the normal working of the device. Also, the app doesn’t get uninstalled until you revoke its administrative access.
Step 1. Go to ‘Settings’ of your Android.
Step 2. Here look for the option named ‘Security’.
Step 3. Now under security, look for ‘Device Administrators’
Step 4. If you find any malicious apps having access then Deactivate it.
Step 5. Now uninstall the dangerous App.
Once the administrator access is revoked you can uninstall the harmful app and eject the virus from your device. Just reboot your phone after you have uninstalled the Apps.
#3. Use Anti-Virus Apps to Scan for Corrupted Files or Apps
Due to Android’s open source policy, it is easy for manipulators to infect any Android device. There are plenty of Antivirus apps available on Google Play Store. No antivirus app can provide 100% protection but they are powerful enough to eliminate all major threat and virus from the smartphone.
Have a complete scan of the Virus and delete all the related files and folders if detected any. These apps could be helpful to remove any major or minor Adware & Malware from the files.
Anti-Virus Apps also provide web protection, real-time app protection and app lock features. Almost all antivirus apps perform the same function so here are a couple of recommendations based on our experiences.
You can even try Trojan & Malware detectors for more deep scanning.
#4. Clean Up Junk Files from Android
Build up of useless, obsolete and junk files can cause the phone to slow down at large. Using an App with an ability to clean junk and cache can help clear up some space and also help the device to run more efficiently.
Many apps require storage space for there working, junk build up can make a good environment for virus injection. Thus cleaning the older files can help the device work at normal and fix any issues if generated.
#5. Update the Apps and Phone Software
The app developers on regular basis release new updates with security patches for more safe app usage. So it is always recommended to update all the Apps.
Google on regular intervals release the updates over OTA with security data to protect the Android.
It is always beneficial to update the device software to protect your phone from malicious virus and kill any if already present.
#6. Remove Battery Draining Apps
You should remove apps which consumes more power making the phone heated. In heated condition, the phone doesn’t work in the way it should due to processing limitations.
Therefore it is recommended to uninstall the battery draining Apps. Keeping the battery within the permissible limits will assist the apps to function in the normal fashion.
#7. Stop Annoying Pop-Up Ads (Adware)
You can stop unwanted and irritating Pop-Up ads with Ad blockers and other techniques. Below is the video tutorial which teaches how you can stop Pp-Up Ads.
You can protect your Android device with the help of various Anti-Virus Apps and Ad-Blocking methods and stay safe.
#8. Factory Reset
If none of the above method works then you have to resort to the final option that is to reset the device. You will lose all your data in the process, so be sure to take the back-up before going ahead. Only backup the media – photos, videos, and music.
Resetting will clean all the data along with any virus or malware. I recommend you to reset the device from recovery mode rather than from device settings. To find how you can do that just Google search for your device.
But in general, the process includes pressing Power+Volume Down key simultaneously after turning off the device.
How to Keep your Phone Safe from Virus?
- Avoid downloading Apps from Untrusted Sources.
- If installing Apps from unknown sources then make sure to install the App with “Verify & Install” Option.
- Do not install hack or crack apps.
