Hi,

I have a subset of users on one domain who are getting an error I've never seen before and cannot duplicate.  These clients all use the web UI in SM.  They get an email in, and try to open/download the attachment.  When they do the following pops up:

                                                                   virus_blocker

This site is blocked because it contains a virus.

Host: mail.<their domain>.com

URI://Main/frmReadMail_Attachment.aspx

Reason: null

Please contact Ben Conner    

Steps I've taken:

The message is in the email pane (rightmost pane) on the screen.  

It isn't all their users who are experiencing this, but for those that are it is 100%.  

I've looked at the .aspx file mentioned in the message.  The datestamp on it is from 2016, and the file is actually a text file.  Looking at it suggests nothing unusual.  

Has anyone seen this before?  The next step would be to do an upgrade to the current version which I will try before the week is out.  The version this is on is SM 14.5.

Thanks!
