Something Norton could not find

I was having an issue with my email account.  There was emails being sent with out my knowledge.  I started using windows live mail client version 2009.  I left it open to eat dinner and come back to find emails that had been sent out with pharmacy links.  Not cool.  I looked in the forums here and say someone say use malwarebytes to scan.  I also used the Norton powerwasher.  Norton products could not find this.  Why is that. However here is the file that was created by malewarebytes on what it found.
