ONE HALF virus
==============
The November 1, 1994 definitions include a new memory definition for
a virus called One Half.  This virus is known to be in the wild in
Europe, especially Russia and the Eastern Bloc countries.  One US
government agency is said to have been infected.

The One Half virus is a multipartite virus that exhibits both 
stealth and polymorphic behavior. In addition to infecting files 
and master boot records, the One Half virus will encrypt data on 
your hard disk.  This is why it requires special handling.

This virus is incredibly complex and we prefer that if you become
infected, please call our Technical Support department and they will 
help guide you through the repair process.   Please do not attempt 
any repairs on your own if you are infected with One Half.

****************************************************************
WARNING: Because of the unusual behavior of this virus, DO NOT 
reinoculate the master boot record or use inoculation technology 
to repair the virus and DO NOT attempt to repair your hard disk 
using Norton Disk Doctor or any other disk repair utility.
