  We are getting the same thing, when trying to send PDF attachments. 

  It doesn't affect all attachments - only some. 

  Microsoft Forefront Protection for Exchange Server has detected a virus.

   

  Virus name:  "JS/Injector.A"

  I had the same problem and now it's enough.
  Some engines don't want to update, gives a code yellow in the monitor.
  This particular problem has been damaged a lot of mail, took a lot of work and time to restore it.

  I have decided to uninstall Forefront 2010 for Exchange, but there was a surprise.
  The IP Block list was still filed, but it seems to be not working because I received e-mail from IP numbers that where blocked.
  I had to reinstall the Microsoft Exchange Transport Service and the Anti-spam agent.
  So again a lot of work and time.

  But at the end everything is up and running :-)

  there are too many things have happened.
