One of my clients signed up with jhoos.com a few weeks ago. Now, his yahoo.com contacts are receiving invites from jhoos.com. He thinks he provided both his yahoo.com user and password to the jhoos.com site. (Ouch.)
- Do I look for malware on his laptop that's generating the emails?
- Did jhoos.com obtain his contact list and are sending emails out via their server? If that's the case, is there any way to tell them to stop?
