The files detected as Troj/Suij-A are the downloader components of an adware application that contain procedures to profile users. The application collects non-sensitive data, such as URL browsing information.
The application is called Keenvalue. It was created by Intermix, who withdrew it some time ago. However, copies might still be present on computers. They will no longer download any of the components, as the host website no longer contains them.
