Corrupt file with SEO

I had a SEO malware problem on a site on HostGator. It corrupted my file html/enterpreneurialpractice.com/wp-content/plugins/jobs-plus/assets/inc59.php It was erased. Now I can’t open the site.

Any thoughts on how to get the site back open? (www.Entrepreneurialpractice.com).

If the site is trashed, then my second option would be to just recover the posts content…and how would I do that?

Thanks for any and all help.
