So I deleted the old website for my employer, and created a new website from scratch. The old website (on the same domain) was hacked and had weird pdfs uploaded. I deleted it all (even the host server is changed, only the domain name remains the same) and removed all possibilities for the hacker to add new pdfs, as I control it. Unfortunately the paths still exist in google cache, but they do not lead anywhere, I redirect all 404 pages (this pdf included) to my home page. Any recommendations to remove these links? I see constant requests (probably bots) going to these links, but it will always be redirected to homepage.
