fobotsco, do you remember a pop-up box telling you a licence manager was being installed? Have you installed any software that required authorization? Have you been prevented from burning any discs? Have you installed any demo and then uninstalled the demo?
Macrovision has products that are marketed to developers to enforce copy protection and a few similar things. They license it to developers as being "transparent to the consumer." Macrovision's software may have been installed by an application to manage a license or to prevent you from copying a CD to another CD or to your hard drive. The application that installed the c_dilla folder may not work if you tamper with the folder or c_dilla registry entries.
Before taking any action, see if you can isolate the application that installed the folder. Searching on file dates may give a clue. Snoop around the Macrovision web site for its licensees.
Macrovision's product has been called spyware because it it is secretly installed and has a secret monitoring function but so far as I know it does no reporting (so I wouldn't call it spyware). Just consumer abuse. Whose hard drive is it anyway? We have long since reached the point at which it is necessary for consumer protection laws to enter the digital age.
