Architecture of the Virus Scan Interface & help me in defining Defining Scanner Groups
The structure of the Virus Scan Interface allows you to combine different products, systems, and platforms to scan your applications for viruses. This is possible, since SAP provides a certified interface for the virus scan products of other vendors.
The partners’ virus scan engines can, for example, have completely different architectures.  However, by integrating an adapter using a proprietary connection, any partner can, however, connect any existing virus scan product to the virus scan interface.
On the SAP side, different VSILIB layers are used to include the ABAP and Java worlds, and to deal with platform dependencies (of operating systems and processors, that is, 32 or 64 bit) in the integration of the virus scan interface.
Use
A scanner group combines multiple virus scanners of the same type to allow load balancing. Since you select the virus scan server using the scanner group when maintaining the virus scan profile, you must assign each virus scan server to a scanner group.
Maintain a scanner group for each product class of virus scanners that are connected to the system using the virus scan server. If you include your own virus scanners with the BAdI VSCAN_INSTANCE, create a scanner group for each implementation of your own scanner and identify these as BAdI implementations.
You can store configuration parameters for each scanner group. These are divided into initialization parameters and scan parameters:
        Initialization parameters are transferred to the virus scan server when it is started, and are required to be able to start the virus scan server. If you use the Business Add-In, these parameters for the method of creating the scan instance are transferred. The parameters contain, for example, the path to the virus signatures.
        Scan parameters are transferred for each scan process and control the behavior of the individual request, such as yes/no for activating the scanning of macros.
For information about which configuration parameters are required or supported by the product that you use, see the documentation for the product.
SAP does not deliver any scanner groups.
Procedure
