MCSCAN32.DLL and MCSCAN32.VxD are the scan engine components for the On-Demand and On-Access scanning, respectively, for VirusScan.

It is recommended that you install this new engine and data files with the most currently released product.

The upgraded files this patch will copy are:

CLEAN.DAT
NAMES.DAT
POLYSCAN.DAT
SCAN.DAT
MCSCAN32.DLL
MCSCAN32.VXD

The files:

AUTO9x.ISC
AUTO9x.SIS

are ISeamless files. The AUTO9x.ISC file is the uncompiled AUTO9x.SIS. It is the AUTO9x.SIS file that is required to be in the same directory as SETUP.EXE.

ISeamless Installation:
______________________________

1. Unzip 9xUP320a.zip into the same directory as your VirusScan SETUP.EXE.

2. Run Setup in interactive or non-interactive silent mode.

3. AUTO9x.SIS will install the upgraded files during regular installation. The install will provide the ISeamless script with the proper destination information.


Manual Installation:
______________________________

1. Unzip 9xUP320a.zip.

2. Halt VSHIELD.

3. Copy

CLEAN.DAT
NAMES.DAT
POLYSCAN.DAT
SCAN.DAT
MCSCAN32.DLL
MCSCAN32.VXD

to your VirusScan directory. When prompted to overwrite the existing files reply Yes.

4. Copy MCSCAN32.VXD to C:\WINDOWS\SYSTEM directory.

5. For VirusScan to utilize the new engine files you need to reboot the system.

NOTE: A reboot is necessary for an engine upgrade. If you are only upgrading the virus definition files, starting and stopping VSHield is sufficient.
