Suspected/partial mime message


The detection 'Suspected/partial mime message' indicates that the message has malformed MIME headers.


Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

An email message with malformed MIME headers is automatically flagged for further attention.

About MIME

Multi-purpose Internet Mail Extensions (MIME) is a standard that allows different types of content (for example, text content using different character types, or audio/video files of different formats) to be included in a message.

A MIME message is sent in two parts: a header that contains instructions for how the content should be displayed for reading, and the body with the actual content. This allows the message to be displayed for the recipient (who may be using a different program or setup to view the message) as closely as possible to how the sender had originally created the message.

The message must be processed by specific applications before the content can be easily read by human users.
