Hiya I really do not understand how to do that as I am not very tech savvy?

Then you have to hire someone to fix the site for you.

I’ve downloaded and unpacked the Zip but dont know how to disable the plugins??

now you have to use the FTP client like FileZilla (https://filezilla-project.org/download.php?type=client) to upload and replace the wp-admin and wp-includes directory to the server.

How do I do that?

Do you have FTP logins for your Hosting Server?

https://ftp.nroc.co.uk is this it?
