Got a Norton error “LU1845.” Haven’t figured it out yet, but did enjoy this piece of Norton humor by James Love, titled “Norton Virus.” He says that we’ll have to reinstall Norton. Before I do that, though, I might give the Blink Personal Edition of eEye Digital Security a try, as described on the Security Now podcast.
“Hi Dane” download SARC Intelligent Updates listed on the link below that is compatible with your system and it will download the latest virus definitions and clear your LU1845 error. It works for me.
Good Luck. PS. keep this link in your favorites, you might need it each time new definitions surface.
