Adds an offline malware scanner. Files and installed apps can be checked against a signature database on your device, with nothing sent anywhere and no key or connection needed. It ships with a starter set of over three thousand known Android stalkerware and spyware signatures, so it detects real threats right away, credited in the app. You can also import your own signature files with the system file picker and replace or add to the database to keep it current. VirusTotal stays a separate option.
