EML - E-Mail Message

What is a EML file

EML is the preferred format for e-mail messages saved by e-mail programs like Microsoft Outlook or Mozilla Thunderbird. It can also contain email attachments or files sent via e-mail. EML files are prone to be infected with viruses and other malware. Thus, EML files should be carefully scanned before opening. Note: .EML files with "funny" names in multiple folders implies the Nimda worm.

EML files are usually plain text files. They contain, next to the body or message of the e-mail, the e-mail header and attached links. Hyperlinks and link attachments can be contained in the EML file as well. EML files are commonly known to be associated with the Nimda virus. Files with obscure names that bear the EML file extension, occurring in multiple folders, are an indication of a Nimda infected computer.
