What are DAT files? Virus definition or DAT files contain virus signatures and other information that McAfee anti-virus products use to protect your computer against existing and new potential threats. DAT files are released on a daily basis.
Being a non-standard attachment format, users from other e-mail clients (like Thunderbird or Lotus Notes) or platforms (like Android, Apple, iPad or iPhone) cannot natively read them. An e-mail containing an winmail.dat attachment looks like an empty e-mail with only one attachment. The original e-mail information like subject, body and attachments is packed into a single winmail.dat file, which in some cases also receives a generic name like ATT00001.dat or ATT00005.eml. Winmail.dat Reader is the only free application that decodes not only the embedded attachments but also the subject and body.
