Hi, I recreated a website for a company that formerly had thousands of spammy Google Search Links that didn't exist. I don't know if they were active at one time, but there still seems to be several of these links in Google Search.

Real Website Links look like:

https://MyClientsDomainName.com/

https://MyClientsDomainName.com/contact-us

Spammy Links look like:

https://MyClientsDomainName.com/1rcvoi6/g20z1w.php?tma=cinema-4d-student

https://MyClientsDomainName.com/44ken/15kcf.php?ayk=microsoft-office-portable-zip

These directories don't exist on the new site, so result in a 403 Page Error... I want to clean up all these links with .htaccess forwarding if possible - but I would be forwarding spam directories to the Home Page and I am concerned that these links may bring unwanted bad link juice to the Home Page of the site... Or would disavow be a better solution - I know this works for external websites linking, but what about bad internal links? I tried searching on google, but didn't really find a good solution - or perhaps I'm uncertain of the keywords to find the solution for this issue. Any help is appreciated.
