That's one of things it takes a while for Google to clean up. Just make sure YOUR business has eliminated all the old, now bad, links.
Redirecting these 404 from deleted pages to an internal page
Please don''t so that. It can look like a quick fix, but there can be long term trouble by using a 301 or 302 redirect instead of a 404 or 410 response (bitter experiences.)
If you're concerned about the user experience, use a custom error page with links on them, but make sure that the HTTP status is either 404 or 410.
