Eddy: The item you suggested deleting:
02 - BHO: (no name) - {02478D38-C359-4efb-9B51-7695ECA05670} - (no file) apparently is used by SBC to hook up to my dsl. This registry item shows up each time after Restart. If I delete it prior to hooking up to dsl, I can't log on. If I open Yahoo! I can log on to dsl OK, but get a message that says I am not logged on. I guess it is a good registry item.
