I think from what I can tell, that Avast has deleted the attachment (if you look at the first screenshot in this thread you will see that the attachment field is blank) and allowed the main part of the e-mail since (presumably) it doesn't contain any viral code. In any case, from the grammar in the text alone, it is clear that it is not a legitimate e-mail. Here is the e-mail header (taken from the message stored in the junk box of my anti-spam program):-
