The SimplLocker ransomware is a piece of ransomware that infects Android devices. The issue with mobile malware seems to be evolving, as this ransomware encrypts files and stops anything else on your Android device from working correctly.
It informs you of what it has done via a ransom screen that demands $21 to decrypt your files and continue using your device properly.
The ransomware is downloaded and installed when you download something online that claims to be something else, but is actually the ransomware. This ransomware is not found on the Google Play Store.
Manual removal of this ransomware has proven to be a difficult task, so we are going to be using an automated app made by avast! in this removal guide.
