Avast Mobile offers us total extra security on our smartphone, this means that it will be constantly analyzing the mobile in search of malware or malicious applications that may harm our mobile.

Another of its strongest points is that it does not cause much impact on your device and it is not an App that will drain your battery until it is exhausted.

BitDefender is currently competing against Avast for the best antivirus for Android award, and if it keeps improving, it might. 

But the real option that places it second is the number of features that the paid version brings. 

For just $ 9.95 per year, Bitdefender offers near-perfect protection against malware, minimal performance impact, and privacy protection tools.

Anyway, if you're not sure about paying for it, you can sign up for a free 14-day trial of this app.

Avg stands out for its simplicity of use and its results in Avtest when detecting malware on our mobile.

Avg Antivirus mobile is considered one of the best cyber protection suites in most operating systems, but the point of why it is in third place is that it is free and we can purchase the premium version whenever we want. 

But Avast and BitDefender beat them by the thousandths due to the power of their analysis, which AVG, can improve a little more, although it is very good.
