Hello, I signed in here to add to this post. I am having the same problem, two waves of e-mails were sent to all my contacts that say they are from my hotmail. They all have no subject, and contain a link that invariably ends with "/find11.html" but has all sorts of domains attached to it. When consulting my "Sent" folder, however, none of these are in there. So they have access to a contact list which suggests that the account has been compromised, but an empty "Sent" folder which suggests spoofing. I've been googling it for a while and I ended up here, but all cases of this particular problem seem to have been occuring in the last few days - so perhaps the recommended Malware problem didn't find it because it's too new. My anti-virus (Avast!) scan also found nothing.
EDIT: After a few more rounds of google during which some more recent cases (today) showed up, I found out the links in the spam mails lead to a Fake AV. If anyone finds anything else, please share, because I get the feeling a simple password change isn't going to help.
RE-EDIT: Found this on SecLists:
Redirects to safetylife2011.org, IP is 188.8.131.52
AVG intercepted a threat on my Virtual Box Lab from 184.108.40.206 as
