Scenario: CGE has a new XenApp image for hosting office applications and will use Provisioning Services to deploy the servers hosting these applications. However, CGE is concerned that their current…

Storing updates on a CIFS share does not prevent the antivirus client from writing to local system files or its configuration within the PVS write cache during the application of definitions.

Restarting servers clears the write cache but does not prevent subsequent antivirus updates from writing to and consuming the write cache again, nor does it make the definitions persistent.

Configuring the antivirus client to store definition updates on a locally, non-provisioned disk prevents the updates from being written to the Provisioning Services (PVS) write cache. This preserves the write cache's capacity and performance, as all frequent and potentially large write operations for antivirus definitions are redirected to dedicated, persistent local storage, ensuring updates are retained across reboots without impacting the vDisk or write cache.

Disabling automatic updates contradicts the security team's requirement for "as many updates as possible" and introduces manual overhead.
