HI, hookster. These error codes are normally associated with Live Update issues also. Have you checked your computer clock time and zone are correct ?
Norton Guru Krusty13 also has the same advice re disabling the registry cleaner, here.
Open N360 and click Settings> Task scheduling and uncheck Registry Cleanup, then Apply.
Windows does a pretty good job of managing the registry these days, and cleaners are not needed.
If the problems continue, a reinstall with the Norton Remove and Reinstall Tool may be needed. The link is here.
If used, run Live Update again, until no more are found.
