I just noticed that I have in my Yahoo draft folder a draft email dated March 22 from ybepur.com that is addressed to almost all of my contacts from my yahoo account. I checked several of the email addresses, and none of them actually received the email. I assume a computer I accessed yahoo mail from is compromised. Scanning my home computers appears to be negative. Any other have a similar problem, and how worried should I be? It looks like it is probably in Italian. I checked my wife's yahoo account, and she does not have a similar problem.
