Suspected SEO poisoning attack.

This morning I found a suspect URL in my NoScript Whitelist. “adinterax.com” and to my knowledge I had not allowed this site. Anyway on doing a Google search for “adinterax.com” I got a pop-up Secure connection failed: "adinterax.com: 443 uses an invalid security certificate. The certificate is only valid for “www.adinterax.com” (Error code: ssl_error_bad_cert_domain) This could be a problem with the server’s configuration or it could be someone trying to impersonate the server. If you have connected to this server successfully in the past the error may be temporary and you can try again later.
