Malwarebytes for Android no longer works when downloaded from third-party sources

As of version 5.34, Malwarebytes for Android no longer works if you downloaded it from a third-party source, such as an APK website or an unofficial app store.

Why this changed

Attackers sometimes copy security apps, add hidden malware, and share them on websites or other app stores. These fake copies can look exactly like the real thing, but they might be built to spy on you or steal your data. To keep you safe, Malwarebytes for Android now only works when installed from the Google Play Store. That way, you can be sure the app is really from Malwarebytes and hasn’t been changed.

What this means for you

If you currently have an unofficial version of Malwarebytes for Android, you will not be able to access the dashboard and will see a screen asking you to reinstall the app to continue using it.

To keep using Malwarebytes for Android:

Uninstall your current copy of Malwarebytes.
Install Malwarebytes for Android from the Google Play Store. See Install Malwarebytes for Android.
Sign in or activate your subscription.

NOTICE - If you've purchased a copy of Malwarebytes for Android from a third party, you may be eligible for a refund. To find out, contact Support and ask to speak with an agent.
