In this situation the sender is trying to get the end user to click on a link in the fake email to deliver an infected file. 
Sometimes it could just be a link to a web site but in this example they use an EXE file at the linked web site.



Note the fake FROM address (inside the parenthesis shows a bogus email address pretending to be the email services domain name).

Note our system added the =SPAM?= tag to the beginning of the SUBJECT line when it found a possible spam indicator.

Also be aware that we would NEVER send you an email telling you use a link to install a file or to fix anything. 

Hope this helps.
