Problem

Norman Virus Control may cause reduced network performance for some client-server applications.

Solution

This problem may occur if you have configured the On-access scanner (Local users) to scan files on network drives. Enabling this option is not necessary in networks where the server(s), which the clients can access, have their own antivirus software. To solve the problem, exclude scanning of network drives by following these steps:

1. Open \norman\distrib\nvc\config\default.ndf on the distribution server 
2. Navigate to Norman Virus Control | On-access scanner (local users) 
3. Under Exclude from scan, select Files on network drives. Save. 
4. Wait some minutes until the clients have replicated the new configuration file from the distribution server (this should normally happen within 5 minutes).

You might have to reboot the client to kick-start the replication. If this does not succeed, try to push the new configuration file using Ndesk. If none of these suggestions succeed you have to manually copy default.ndf from the distribution server to \norman\config\config.ndf on all clients.
