   That's usually a sign of a (poorly constructed) self-extracting
archive, in which case it should be harmless.

   That looks like a message from some code which a fellow wrote to save
UnZip (6.0) from a particular problem in a (malicious) zip archive which
can generate a very large output from a harmlessly-small-looking archive.

   I believe that some GNU/Linux distributions (Debian?) may have
incorporated that code in their UnZip programs.  I haven't looked at
that stuff for a while, but I'd expect there to be an option to disable
the check, which might be the only problem.

   Worst case, fetch an unmodified UnZip 6.0 kit, build that, and use
it.

   Of course, it's also possible that your archive is corrupt.
