We're used to associating danger with Web sites and emails that
might have viruses, but the truth is that the Word document you

Trace utility gives you a security risk rating on the presence of
hidden information in your Office documents. Among other things, it
looks for server names, macros, email addresses, track changes and
comments. It works for Word, Excel and PowerPoint. The ratings
you'll receive are High, Medium and Low.
