    The Gruxer ransomware virus is made up of three modules:

    1. Encryption Engine – The Gruxer ransomware virus features a main module that processes user and system data.
    2. JPG Worm – A distinctive feature of the Gruxer ransomware virus is that it includes an image worm. It processes all found JPG image files that are then rewritten in the PNG format.

By using this module the Gruxer ransomware virus prevents the users from using manual methods of removal. It displays the ransomware note and can only be removed effectively via a quality anti-spyware tool.
