Both includes a license of eScan Corporate for MailScan (as a separate setup file). eScan Corporate Edition for MailScan operates as a full 32-bit device-driver based real-time scanner. eScan protects all the files on the local hard-disk, where your mail-server is installed, from virus infections via other mediums (Floppy, CD, etc.). eScan Corporate Edition for MailScan has the eScan Management Console.
