this is a ' complete ' removal of the rootkit...not a partial you can find on other sites.


This only removes the cloaking...
November 2, 2005 - This Service Pack removes the cloaking technology component that has been recently discussed in a number of articles published regarding the XCP Technology used on SONY BMG content protected CDs. This component is not malicious and does not compromise security. However to alleviate any concerns that users may have about the program posing potential security vulnerabilities, this update has been released to enable users to remove this component from their computers.
