I will not tire of insisting on the importance of having a good antivirus on your Android mobile. Not even the price is an excuse, since there are some very good and free, such as Avast or AVG. The risk is real, not just for the data you have on your mobile. The almost 100% synchronization that it has with your other devices, such as the tablet or the computer, can turn it into a true Trojan horse.
Well VirusTotal is a second layer of security. It does not replace, nor does it intend to, antivirus, but it completes them. Once installed, makes an analysis of all applications that you have on your mobile, from the system ones to those downloaded from Google Play, through those of alternative origins.
Its interface is very simple and, therefore, very easy to use. Use a color code. It takes the hash (unique number that identifies each file) of each app and checks it against its database. VirusTotal’s servers have a large library of files analyzed and verified with more than 40 different antivirus. If everything is in order, next to the name of the app an Android appears in green.
If a question mark in blue, it means that there is no information about that app yet. VirusTotal then allows you to send the application to its servers so that the community that makes up VirusTotal, created by the veteran security consultancy Hispasec, but which works independently, can analyze its code. You must be registered in VirusTotal to be able to send apps.
The last option that may appear is that of a Android in red. It has not happened to me, but that indicates that the scanned app appears as dangerous in one of the VirusTotal databases or the antivirus it uses. If there is only one that labels the suspicious app in red, it may be due to an error in your virus engine, but if there are several, delete it as soon as possible.
VirusTotal can be downloaded from Google play
