Aside from the rather expensive "Virus Bulletin", print sources of virus
information are hard to come by.  There are some vendor newsletters, but the
best of these, "F-PROT Bulletin" is limited to customers of Data Fellows.

A new newsletter, "Virus News", is now "distributed freely to those 
interested in keeping up with the virus threat."  It is put out by 
Sensible Security Solutions Inc., the Canadian distributors of Dr. 
Solomon's Anti-Virus Toolkit.  You can contact them at secure-l@magi.com 
or 100016.2432@compuserve.com.

So far the issues that I have seen have been both informative and free of 
hype.
