Now, these Android malware can be removed from your phone when you discover you have them. The first thing you should do is to get rid of the infected app before it causes further damage to your device. Here’s how to do it:
SHUT DOWN FIRST
This is to prevent the malware from causing any more damage than it already did. It also allows you to think carefully. You can use this opportunity to research about the apps you have, to figure out which one has the malware, and what it may have downloaded without your consent.
SWITCH TO SAFE MODE
When you turn the device back on, you should switch to Safe Mode first, to limit the damage the app could do. For most Android devices, hold down the power button once your device is on. This should bring up a few power options, including Safe Mode, Emergency mode or something like that. now choose this mode and wait for your phone to reboot.
GO TO SETTINGS AND FIND THE OFFENDING APP
In Settings, scroll down to Apps, and click it. Look for a list of all your current apps, then scroll till you find the infected app causing you problems. Click on it, and select Uninstall.
UNINSTALL THE APP AND DELETE ANYTHING SUSPICIOUS YOU FIND
Do this by selecting Uninstall. This will remove the app from your phone. Also, you might want to go through your app list and remove any apps you think might be containing malware. There could be apps your phone automatically downloaded. In some cases, you will not be able to uninstall the app, because the Android malware gave itself special protection through administrator settings. You can fix this by going to Settings > Security > Device Administrators. You can then disable the app’s administrator access.
DOWNLOAD SOME MALWARE PROTECTION
There are a number of apps you can download to protect your Android phone, scan for viruses and other malware. You could download 360 Security, Avast Security, AVG Antivirus or any app like that from the Google Play Store. Also, make sure to keep your device updated on the latest Google security patches.
