The e-mail message should have been directly delivered to you or sent as an (mail item) attachment to you.

  • Open the email in a new window by double-clicking it.
  • Click the expansion button in the lower right corner of the Options toolbar box.

  • Find the headers under Internet headers:.

How to submit SPAM messages to Trend Micro

1. The spam emails should be saved as .MSG or .EML format
2. The spam sample should be the original mail, not forwarded mails since forwarded mails do not contain the original
    mail contents and may contain customer related information that could lead to False Positives.
3. Original spam mail can be obtained by the following steps below:
    > Create a folder
    > Drag all undetected spam samples to the created folder
    > Place the undetected spam samples in a zip file and password-protect it using the word "novirus" without the quotes
    > Send the zip file

Here are the email addresses on where to send the samples:  - Undetected spam sample submission mailbox - Legitimate mail tagged as spam submission mailbox

Note:  Customers will not get a reply.

Please be informed that TrendMicro has a large collection of Honeypots for collecting new and emerging spam threats. Once samples are received, they are automatically sent to the automated spam processing team.

  2. File Sharing should be enabled on the client machine
  3. "Remote Registry" Service should be enabled.
  4. On the windows firewall, select "Windows Management Instrumentation (WMI)" as an exception program to allow in bound WMI calls. Also, make sure the "File and Printer Sharing" is part of the exception list.
