Avast Mobile Security has a good reputation in the world of security on the Internet.

Its protection against malware is outstanding with minimal impact on performance. It includes a call blocker, VPN and junk cleaner. It also has the photo vault as well as WiFi network security. RAM booster, anti-theft and web shield.
Kaspersky Mobile Antivirus offers absolute protection at a reasonable price. Its malware detection is top-quality with a minimal impact on battery life and it also comes with a call blocker, Wear OS support and other extras. The only drawback is that it's not as user-friendly as some of its competitors and it doesn't offer a money-back guarantee.
AhnLab is a company from South Korea, is another excellent option. It scored near-perfect in my hands-on tests and labs but it's a bit less user-friendly interface. It's not as active in social media or community forums like other apps on this listing. However, it has great detection rates for Android malware according AV-Test and AV-Comparatives (but it hasn't been tested by either lab since the year 2015).
