We change the ZyWALL break mechanism for the infected file. The ZyWALL just

breaks the first infected file packet and stop track the file session in the previous

mechanism. The old one has better performance, but there is a risk that it couldn't

break the file with more than one virus. Now ZyWALL breaks the first infected file

packet and the following file packet as well. It is safer but downs performance for

handling infected files. We also fix the line-assembly bug for FTP and HTTP in this

enhancement.
