1) Do I have a virus in my phone?

Android viruses are difficult for the average user to detect, as hackers learn to conceal their activity. Fortunately, there are a few tricks that can alert you to a possible Android infection.

1.1) Abnormally high Internet consumption

Some Android viruses increase Internet data consumption by forcing your phone to repeatedly connect to a website, click on an advertisement, download large files, or send messages.

To check the internet usage of your phone, I advise you to download the My Data manger app. After 24 hours, launch the application, choose Application and scroll down to identify the applications that consume the most and that you never use.

If, for example, you see abnormal data consumption by Google play or another unknown application, then know that you are infected.

Some Android viruses download apps from Google Play without your knowledge. You should therefore be wary if unusual applications appear on your Smartphone.

For that, go to Settings -> Applications and scroll down to identify all those mysterious apps that installed themselves. Select one by one and have it uninstall.


1.3) Unwanted advertisements

If pop-ups and other types of pop-ups that exceed the normal behavior of an app could indicate that an Android virus has probably installed on your Smartphone.

1.4) Abnormally high invoices

Some Android virus automatically send SMS to premium rate numbers and this has a direct impact on the amount of your bill. Some Android Viruses send messages sporadically, for example once a month, so as not to arouse your suspicion.
A thorough reading of your invoice can help you detect an Android virus.
