VSE Auto update will pull up everything (all the types of updates) available -so it will look for these packages too VSCANCEU1000, EXTRADAT1000, BOCVSE_1000, VIRUSCAN 8700 and will report it in the update log.
If you don't want to see this message then I will suggest you to create a new update task and uncheck the options accordingly from Update options of update task.
If not using ePO then also if the options are checked in the update task then the updater will compare the update available on the client machine against McAfee update website and will report this message.
