VirLock acts differently than any other ransomware before – it locks screen of victims device and as a polymorfic parasitic virus infects files on user‘s device. After VirLock infection, files are morphed into encrypted executables containing the virus body. Another part of its payload is then responsible for the LockScreen functionality and for displaying the ransom screen.
