Today, digital devices make our lives more convenient than ever before; however, they bring not only benefits but also concerns about cybersecurity. According to the report, people waste hundreds of millions of dollars every year due to cybercrime.
Android phone is increasingly prevalent around the world, but the biggest disadvantage of Android systems is the security. It is more vulnerable to fighting virus and other malware. People are more likely to have antivirus software on computer. When it comes to Android phone, majority of users do not use any security technology.
Sometimes, bad behavior can be attributed to a virus or other malware and it can be difficult to tell what is to blame.
Worry about your phone is infected by virus?
In this post, we are going to share every knowledge you should know about cybersecurity on Android, including how to perform virus removal for Android.
Virus Removal for Android
If you do not have a third-party antivirus app on your Android phone, there are some symptoms to discover whether your device is infected.
1. Battery drains faster. The virus usually is running in the background and taking up your resources. In result, you may find that the battery runs out faster.
2. Data usage increases. Another important sign that your device has a virus is the rapid consumption of data traffic. The virus is usually designed to steal your information and privacy via internet.
3. Apps keep crashing. If your apps start crashing regularly for no reason, you phone could be infected by a virus.
4. Unfamiliar apps appear. Virus, Trojans and other malware may download apps that seem legitimate, but they are not. If you see an unfamiliar app appearing on your phone but you did not download it, you should check it carefully and perform virus removal for Android.
5. Adware pops up. Most ads can be stopped by ad blockers, but if you see pop-up ads on your phone even when your browser is closed, chances are that your device has a virus.

If you suspect your Android phone might have a virus, there are two methods you can try to get rid of it.
Method 1: Remove virus from Android using a third-party antivirus app
We use AVG Free AntiVirus for Android as the example to show you the procedure.
Step 1 Open the antivirus app from your app drawer and tap the Scan Now button. It will scan and check all files and apps on your phone for any virus.
Step 2 If a virus is discovered, tap Resolve to remove it and uninstall the malicious app.
Method 2: Clean viruses out of your phone manually
If you do not like antivirus app, you can get rid of virus on Android manually as well. 
Step 1 Boot into Safe Mode on your Android phone. Press the Power button to activate the power-off screen, hold down the Power off option for a while until you see the Reboot to safe mode message. Tap OK to move on.
Tip: Android will not load third-party apps in Safe Mode. That could help you to identify and remove malicious app manually. (Do not need Safe Mode? Just turn off Safe Mode on Android phone.)
Step 2 When go into Safe Mode, run the Settings app and head to Applications, App Manager, or similar option.
Step 3 Select the suspicious app and press the Uninstall button to remove it from your device. If the Uninstall button is unavailable, move to the next step to remove administrator access first.
Step 4 Head to Settings -> Security -> Device Administrators. Select the malicious app and press Deactivate. Now, you can back to the App Info screen and uninstall it.
Step 5 After removing virus from Android phone, you should clear cache data and APK files. Next, press the Power button, touch the Restart option on the power-off screen to go back to the normal mode.
Note: It is a bit complicated to remove virus manually, but this method does not require any extra apps.
Sometimes, important files may be deleted when removing virus on Android. Antivirus apps, for example, may treat your files as virus because it contains sensitive information. Don't worry! FoneLab Andorid Data Recovery could help you to get it back.
Compatible with all Android devices from major manufacturers.
Apparently, Andorid Data Recovery is an excellent tool to retrieve lost files and data during virus removal on Android.
How to recover deleted files after virus removal
Step 1 Connect Android phone to your computer
Download and install Andorid Data Recovery on your PC. There is another version for Mac machines. Then launch it from your desktop and hook up your Android phone to your computer via a USB cable.
Note: You need to turn on USB Debugging mode on your phone in Settings -> Developer options. If you cannot find it, follow the on-screen instructions to achieve it.
Step 2 Preview lost Android data
After your phone is detected, you will be presented the data type window. Select what data you want to recover, like Contacts, Messages, and more, and click the Next button to open the preview window. Here you can look at you the content of your files.
Step 3 Recover deleted files in one click
Tick the checkbox next to each file that you want to get back, and click on the Recover button at bottom right corner. When prompted, select a folder to save your files and initiate data recovery after virus removal on Android.
In order to avoid future attacks after virus removal on Android, you should follow the tips below:
1. Always install apps from Google Play Store unless the sources are reputable. Most viruses and malware are delivered by third-party APK files that you installed from internet. Once you enable the Unknown Sources option, your device will lose any protection. Even though you want to install an APK, make sure it is downloaded from trustable sources.
2. Avoid cloned apps. Most apps downloaded from Google Play are safe, but sometimes they may contain malicious code. That will visit your information, like account. We suggest you to use the apps from famous developers in Google Play. Plus, you should read the reviews carefully.
3. Read app permissions. Many people tap permit on all the notifications when installing an app. No matter where you get the app, check the permissions and learn to say no.
4. Update software. Google and your manufacturers release updates for Android frequently to introduce new features and fix bugs. It is well known that cyber criminals utilize these bugs to attack your device, so you should install the update once there is an available one.
5. Have an antivirus app. Android does not provide firewall or similar features. However, you can find a proper antivirus app according to our reviews above.
6. Reset to factory settings. The most drastic solution of virus removal on Android is to reset your device to factory conditions.
The downside is that all your files will be deleted, so you should back up your phone with Aiseesoft Android Data Backup & Restore.
Learn the detailed steps here to backup Android.
Now, you should understand what you can do when you suspect that your phone is infected by virus or malware. First of all, Android devices will perform slower as time goes by, but if it displays the symptoms we shared in the first part, chances are that your phone has a virus. Nevertheless, you can remove virus from Android phone with two methods. Antivirus apps are easy to use, but you have to download it from Google Play Store.
On the other hand, you can try to remove virus in Safe Mode following our guide. Moreover, we also shared a way to recover lost files during virus removal, FoneLab Andorid Data Recovery. We hope that our suggestions and recommendations are useful to you.
