Can you prevent this program from running at startup? Go to Start - Run. Type in the box msconfig then click OK. In the dialog box that comes up, click on the Startup tab, and see if eBayTBDaemon.exe is in the list. If it is, remove the tick from the box alongside it and OK out of the configuration utility.
I don't know of any problem with eBayTBDaemon.exe, so if it is giving you difficulties perhaps your computer is short on resources.
