Trend Micro eMail ID is a browser plug-in that helps you identify legitimate email messages in your inbox.
It uses a two-step check to verify the authenticity of messages from hundreds of major companies, and then displays the result in the FROM area so that you will know what is real.
This helps you avoid opening and acting on phishing messages attempting to spoof real companies.
