Fix Corporate Website Hack

Hello, Our company website [login to view URL] is having malicious pages created that are showing on the Google search result. Currently when you browse through the website there are no redirects to porn or anything like that, however I need to have the ability of hackers to create new links on the back end removed and all current ones deleted. Evidence of the hack are as follows: Google 'Mejority' In the top result select 'More results from [login to view URL] >>' Then in the last few pages you will see the results that I have attached to this project page. (the links are either porn related for essay writing related and indian language). Google Search Console only allows me to temporarily delete the links so they just re appear (or new ones created). I require a permanent fix. It is a Wordpress website but Sucuri and other security apps are installed to protect it as much as possible. What I am requiring as part of this project is: - clean up the website and remove all non website links - find the source/way the hackers are doing this and put measures in place to help avoid this Please let me know how they are doing it and what you will do to fix it and I will award you the job. Then we can have an ongoing business relationship for the site.
