sterndata on "Site loading through domain that is not mine"

I've been trying to figure this out for two weeks, and my hosting company (Bluehost) tells me it is a WP issue. Today they shut down my site for malware, which has been removed, but it is still doing it.

When I go to my site, my domain and all sub-domains (wendiriggens.com) show as "waiting on" or "transferring from" or any of the other "...from" statuses in the bar as from "ecuadorianservices.com". Two weeks ago, it was a domain for a hotel in India. Clearly these are not places I have any association with, and I cannot figure out why my site would be loading through these domains.

Any idea? Is it a WP issue, or a server issue, or something else?
