C:\Program Files\Dell folder opens when XP starts?

I have had to reinstall Cineplayer (supplied by Dell with my new E521) and have found that all users get this folder (c:\program files\dell) opening up automatically when logging in. This has only started happening since I reinstalled Cineplayer.

 

I cannot find any start file or registry entry that is causing this but I suppose there must be. I have removed the program again and the problem stops. Reinstall and the problem reapears. Help!
