I keep getting the following message from trusted mail users "Your security software found malicious content in the attached email message. For your protection, the message was converted into a less risky text file. If you decide to read it, please do not reply or visit any websites that it mentions. You should delete the text file as soon as possible." The sites are @havering.gov and @aviva.com and are safe so how can I set my Trend Micro to allow these messages?
