Actually there are two versions of pkunzip.exe, one with the -s scramble
with password option, and the so-called 'European' or 'export' version,
without.  The one above is the export, and the full version is the same
date and time but the size is 23,528.
 
The European version identifies itself as version '1.1.' instead of '1.1',
and of course leaves out the -s option from the online help.  I have both
on my system, with the European renamed to euunzip.exe, and F-Prot 2.06a
proclaims both clean and here are the Validate codes, as well as 32-bit
CRC's of both files:
 
          File Name:  \bin\pkunzip.exe
               Size:  23,528

               Date:  3-15-1990

No doubt more information than anyone would need.  :-)
