Question about Outlook Express

Hi.
i am receiving spoof emails constantly.
the problem is that changing my password wont help, i even added more protection with the authenticator, but before it i had chosen the option when you get the code via sms  but then i started getting 1-2 messages per day even if i didnt try to use my outlook.
I scanned my pc with windows defender, and Kaspersky internet security 2013 witch is the best rated anti-vir on market and my pc is clean so i dont need to think of it anymore, luckily nobody (i think) from my contact list gets those spams, cause of nobody has complained.
But the fact that tried everything from security to changing aliases didnt help. even if i change my name on screen the next time i get the msg it has the new name on it.
ill add the copy of the msg source so maybe you can tell me if my pc/account is compromised or is it just a regular spoof and i dont have to worry?
