They're pretty rare in files from the internet, but normal people don't really regard "files from the internet" and "this attachment of an email" as separate concepts. In traditional business (like banking, where I have my experience) macros are EXTREMELY common. Both in local files, and in what normal users would consider remote files (from intranet sites and email).
