I am running Spybot S&D version 1.5.2 on Windows XP, SP-3. Spybot advised one problem couldn't be fixed. Reason could be associated files still in use. To try re-start. Did and same result. The best I can determine it is something to do with a registry key: Windows Explorer; [SBI $6107D172]. I would like to clear out this problem if someone could help me, I sure would appreciate it.
