Android viruses have several objectives some run malicious processes on your device, others steal your personal information and others download additional software, which may not always be malicious. Whatever you are doing, you do not want them there.
Avoid Android viruses and malware
• Do not install applications from outside of Google Play unless you know what you're doing: this functionality must be disabled by default, but to verify you can open the configuration menu of your phone or tablet, go to Security and then make sure the Unknown sources option is disabled.
• Avoid cloned applications ]: 99% of the time you will be safe downloading applications from Google Play, but malicious codes have been found within the applications. Avoid downloading what appear to be cloned applications from unknown developers, or applications that simply do not do what they say they do
• Check the application permissions : no matter where you are installing an application from, verify your necessary permissions before pressing Install. Never allow administrator permission of the application device, which prevents it from being deleted.
• Keep Android updated : the latest version of the Android operating system will not necessarily be available for your phone or tablet, but you should verify that it is as up-to-date as possible.
• Install an antivirus application : you do not need to install antivirus on Android, but it can give you peace of mind if you are worried about viruses, and applications also have other useful functions. Our favorite antivirus option is BitDefender but there are also many other options for mobile security software in this article separately.
If we already have a virus, how does it get deleted?
Put your phone or tablet in secure mode . This prevents third-party applications from running, including any malware. On many devices, you can press the power button to access the power off options and then press and hold Power Off to display a option to restart in Safe Mode .
If this does not work for your device, you should search on Google 'How to put [su nombre de modelo] in safe mode' and follow the instructions.
Open your menu of settings and choose applications then make sure you are viewing the discharged tab . Most likely you know when your device started to behave badly and, you can usually align it with a new application that you downloaded.
If you do not know the name of the application you think has infected your Android phone or tablet, review the list and look for anything suspicious or you know that you have not installed or should not be running on your device.
In most cases, this is all you need to do to remove the virus, but you may occasionally find that the Uninstall button is dimmed .
This is because the virus may have taken control of the status of device administrator .
Exit the applications menu and tap configuration, security, device administrators . Here you will find a list of all the applications on your phone or tablet with administrator status. Simply uncheck the box of the application you want to delete then touch disable on the next screen
You should now be able to go back to the application menu and delete that application. With the virus now uninstalled from your Android phone or tablet, all you need is to restart the device to get it out of safe mode.
Now that it's working properly, it's a good time for back up the important data you have stored on the device and install an antivirus application from Android to protect it from any future viruses that may arise and avoid extra behavior ños.
