Wildtangent entry in your startup menu...do you have this program installed? Evidently at one point you did and perhaps uninstalled it, or it was installed behind your back by another program. You can check in Add-Remove Programs to see if it's listed so you can uninstall it if you don't want it. Otherwise reinstall it.
In any event, I would go to Start/Run type MSCONFIG and look at the startup tab to uncheck it so it doesn't attempt to start and your bootup. If it's not there, look in your Start/Programs/Startup folder and delete it by right clicking instead.
