No, it is not needed on startup. A lot of companies write their programs to be user friendly and have them automatically load on startup. You may remove it from the startup list either by selecting properties, of within the program itself. If the program does not allow for you to turn it off you may use msconfig to remove it from the list of startup items. Remember that the more items that you have load at startup the slower the load time will be.
