Thanks for all the suggestions.

I just want to report, that it has been 17 days since it happened, it has NOT happened again, so far, keep my fingers cross.

I deleted ALL my contacts from yahoo.com right away, 17 days ago, when happened. exported the contacts into a file, virus checked the file and imported into another email account, and absorbed the loss and moved into a different account. It took me 1 evening and 1 morning to take care of it, so far so good. I am now using the new email account and slowly phase out the old account. So far, there is no more trouble... keep my fingers cross,
