Did the error message only occur after you had installed spybot? If it is, then it is probable that it is something to do with that. If it isn't then we'll have to wait for a more advanced user to try to help.
It might have something to do with your spybot...i can't remember the exact name...'definitions' for the program. If you can find an update button on the program and update these definitions, then restart.
It may not be to do with the definition things, but thats my guess. No harm can come of it...unless anyone else has a better idea...which they most likely will
