It is a file from norton av and not to worry abt it, while takes quite cpu resources during startup. Better to check if it is a malware.

Norton / symantec virus definition updater.
   
It's a virus. Chews away at your registry files
  Adam  
This is a safe Norton Symantic file that watches for new virus, worm, trogen definitions and initiates a process to download them if the system operator has not run a Live Update for virus definitions for a set period of time. Set Norton to automatically update definitions at an obsure hour every day and this file will no longer need to run on startup.
