Email presumably comes from a person named Peter Kruse (from Denmark) claiming that recipients of the email sent a virus by email and to open an attached file ("in.zip") to remove the virus.
Intent of the Email
This may be an attempt to install malware on recipient devices by use of the attachment ("in.zip" file). Never open mysterious attachments from unknown or untrusted sources, particularly if it's irrelevant.
