|There is program that wants to run on startup and that is depending on this dll.|
Go to start - run and type: msconfig
In the popup screen you will see all programs that will run at startup.
Also their owners (companies) and the path to their exe. (in command colomn)
Look for something STRANGE
Un-select the line and it wont give you the message anymore
You can also delete the exe if it is still on your system.
