I just got this in my yahoo mailbox. If you use webmail, yahoo will catch it, but if you use outlook, watch out.

so how do you know if someones jacking your email?

The sender isnt associated with yahoo.com. Look at the address, noreply@yahoo.com. If it was real, the return address would be something like support@yahoo.com. Also, yahoo would not attach a file. The attached file has a virus.

ohhhhh now i get it
