Denying that there is malware on Android would not make any sense, since there is, and in quantity . Nevertheless, Malicious software does not work just like on computers , since unlike in these, on Android an application can not work if we do not give permission . On a PC, it is totally normal that when browsing a web page, we are downloaded an executable file, and you have bad luck, This can stay in your machine without you noticing .

The security of Android prevents the APK files from being installed automatically, so everything that is hosted on your terminal is your responsibility.

Adware

Sometimes, we can buy a mobile that comes from the factory with adware . This is a software embedded in the system that is responsible for showing us advertising, sometimes, even randomly. Some Chinese mobiles, such as the Xiaomi, may come with a store-modified ROM that displays these types of ads, and the only solution is to change the ROM to the device , since the Adware is installed in the system.

In other cases, we can download an application that contains Adware , and start seeing how suddenly our mobile is full of ads. Delete the latest applications that you have installed , and in extreme case, re-establish the factory terminal, to make sure that no trace has been left.

Luckily, Android’s permissions management system allows us identify a virus on our phones . As you well know, this management of permissions in Android is manual, that is, for an app to access the GPS, phone, camera and others, you must accept these permissions both when installing it in APK format, as well as the time to run it directly if it comes from the Play Store.

If you download a flashlight application, it does not make sense for the package to request access to calls . If you download a calculator app, it does not make sense for you to ask for camera permissions. In general, it is quite easy to detect malware, except in some cases where we have no escape.

There are occasions in which, applications that do not request extra permissions, and that have a “normal” behavior, collect information about us, to send it to external servers . Unfortunately, there is no way to discover this type of malicious software. To avoid it, We always recommend using the basic applications that come with your phone, and not replace them with others .

The best antivirus is yourself , so avoid downloading this type of applications, and use your common sense to prevent your terminal from getting infected.

It can be quite complicated to find the route where the files that infect you continue to be hosted, so in these cases, the best thing is a factory re-establishment.
