:You may well be fine.
There are, because MSN infectors morph so often, specialist tools used in these cases, as most AV and generalist anti-malware tools will not have the infectors in their databases.
What we really need to have is your friend to pay a visit to the Security Cleanup Forum for a checkup. The issue is complicated: the way these infectors work is by stealing your Contacts list, and spoofing the "from" Header. Since you are receiving messages supposedly from your friend, his computer most certainly needs to be reviewed.
That was my thinking exactly. I'll see if I can convince him to do just that. I know he runs AV and firewall w/ router, but I don't think he uses safe browsing habits.
