Yahoo mail infected by virus?

Question

I have had lot of people from my address book complaining that they have recently been receiving spam mail from my account. The email contains attachments like
Attachments00.HQX ,Video_part.mim
I have run complete virus scans with up-to-date virus definitions many times. Even tried formatting my computer, but nothing worked. I dont believe the virus is residing in my computer. So where is it ?? and how do i remove it???
and i dont want to change to a new yahoo email id..

Edit :
I have tried changing my passwords also.

Edit :
Since i have formatted by hard disk, that removes the question of having a keylogger. I use McAfee Virus Scan enterprise, along with windows defender and Ad-Aware SE Personal edition. I have also ran the online virus check provided by Microsoft @ Windows Live OneCare.

Answer 3

there is either something in your computer or your mail. if i had name and pass i could help you with it.

heres some suggestions for you to check also.....
find any antivirus software (nortan, panda, whatever)do a scan!
second: get a firewall, keep it on all the time.(zonealarm is a good one) get spysweeper too to get rid of other milicious files (trojans and other files)
if this doesnt work contact a computer pro at $40/ hour or contact me... i can atleast look at your mail for you if you want me to.
hope you get this taken care of soon or youll have some very friends. :((
