1. Avast Mobile Security

Superior protection for free

 Has a free version 
 Advanced options in both versions 
 Free version has ads 

Avast has been around for quite some time, keeping our PCs safe from outside threats, but it has also developed an excellent product to protect your Android device(s), as well. The best part? It’s available for free. The free version is supported by ads but you can remove them for a small monthly or yearly fee.

The free Android version not only provides scanning and monitoring against malware and vulnerabilities, but it also offers a bunch of other useful features. For instance, you can filter out unwanted calls and verify your Wi-Fi’s security. There’s also an anti-theft toolkit that you can use to lock your device or erase its content if you lose it or it gets stolen.

Paying for a premium version will not only remove ads, but will also add some extra features to make it worth your while. One of these is in-app locking which places a PIN/pattern/fingerprint block on certain apps, effectively preventing malware from launching them automatically. Another one is secretly taking photos or audio from your phone when it goes missing.

If you’re willing to pay the extra cost, you can even go for the premium ‘Ultimate’ bundle option, which is accompanied by a VPN, password management tool, and a system cleanup option.
