After failing several times to solve my Norton Internet Security 2005 referrer problem (localized swedish version, not the same layout as the english, therefore hard to follow the english instructions), I found the solution that helped me:
I changed “https://localhost/…” to “https://127.0.0.1” in the “option_value” for siteurl in the “wp_options” table.
As I could not add “localhost” in Norton, just the net address, changing the information in WordPress database instead helped me get rid of my most irritating problem when working with WordPress on localhost.
