A spyware company (<www.cydoor.com>). Installs an executable called cd_load.exe in the Windows system directory. This loader is started everytime Windows starts. To remove it , a) rename the file, b) search for cd_load.exe in your registry (using regedit) and remove all entries where it appears.

I have noticed it after installing Freebase, a file sharing program (located at <www.oreality.com>). Strangely enough, the banners displayed in the program are displayed whether cd_load exists or not. So cd_load does something different than fetching banners..
