You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: clamav.rb
    path of file: ./repos/postal/lib/postal/message_inspectors
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module 
    
      def inspect_message(inspection)
        raw_message = inspection.message.raw_message

        data = nil
        Timeout.timeout(10) do
          tcp_socket = TCPSocket.new(@config.host, @config.port)
          tcp_socket.write("zINSTREAM\0")
          tcp_socket.write([raw_message.bytesize].pack("N"))
          tcp_socket.write(raw_message)
          tcp_socket.write([0].pack("N"))
          tcp_socket.close_write
          data = tcp_socket.read
        end

        if data && data =~ /\Astream:\s+(.*?)[\s\0]+?/
          if ::Regexp.last_match(1).upcase == "OK"
            inspection.threat = false
            inspection.threat_message = "No threats found"
          else
            inspection.threat = true
            inspection.threat_message = ::Regexp.last_match(1)
          end
