Android is the most widely used operating system in the world and there are over 2 billion monthly active devices using Android today. Its widespread use and its fragmented nature make it vulnerable to malicious attacks of the worst kind.

Android’s highly fragmented nature and the fact that it deploys an uncountable number of custom ROMs on thousands of phone models make it a security concern of nightmarish proportions. Lately, Android phones are being increasingly targeted by attacks looking to scam or make a quick buck off the unsuspecting user.

Your smartphone is an intimate device that has your most personal information. Google and other device vendors keep their platforms secure and do due diligence for keeping your device safe.

But Android developers can only do so much!

Protecting your device from viruses, malware, and other threats is primarily your responsibility, and there are several things you can do to stay safe and keep your phone out of harm’s way.

Best Practices for Keeping Your Android Device Safe

  1. Keep the phone OS updated.
  2. Don’t side-load unverified third-party APKs or hacked apps.
  3. Don’t install apps that you don’t need.
  4. Be on the lookout for virus symptoms and identify if your device is infected.
  5. Install apps only from recognized stores – preferably Google Play Store. Stores like Amazon App Store are trustworthy, but you need to enable unknown sources to install it
  6. Don’t allow apps from Unknown Sources (unless you really have to, and be sure to disable it later)
  7. Take a moment to understand App Permissions on Android and read them before allowing access.
  8. Never keep the bootloader unlocked.
  9. Don’t root the phone unless you know what you are doing
  10. Use the built-in security features of Android (Access lock, encryption, and multi-factor authorization, etc.)
  11. Backup your Android device regularly.
  12. Use a trusted security app. (Choose one from the list below)

The practice of using a trusted security app is easy to state but not as easy to implement. A search for Antivirus on the Play Store lists hundreds of applications. How do you choose an app that provides good security, and avoid the ones that just provide a false sense of security?

This list compiles apps that are the best security apps for Android.

How We Compiled this list of Best Android Security Apps

Two of the best independent antivirus security labs, AV-Comparatives and AV-Test,  periodically release the results of their security tests done on security software across all platforms including mobile. These tests are conducted with hundreds of samples of the latest malware affecting Android devices and the performance of the apps against these threats is noted to generate this data. It is the best way to determine which Android apps perform the best and help us get together this list of best Android security apps.

Since this data reflects the ability of an antivirus app to actually protect the user from malware threats, the apps highlighted by these reports from the baseline criteria for this list.

In addition to this, we look at the apps from a user’s perspective – pricing, features, performance, and other distinguishing qualities of the app that the users would find both useful and beneficial.
