Updating the Virus Definitions
This document provides three different ways to approach virus signature file updates for CA eTrust
Antivirus clients.
1) Do Nothing
The virus signature file continues getting updated every time the workstations are restarted or whenever
the updates are pushed down, but the changes are lost upon reboots. On fast-switched networks this
has a negligible impact on the boot-up time.
The workstations have the latest definitions at all times. The only downside of this method is that,
with time, the signature file keep growing bigger. Therefore, it is recommended to schedule a Thawed
Maintenance Period at least twice a year to make the updates permanent.
) Manually Update the New Virus Definitions
1. Using the Deep Freeze Enterprise Console, set the workstations to reboot into the Thawed
state.
2. When the computers are back on, right click the eTrust icon on the system tray to access the
menu.
3. Select Download Updates Now, this will automatically download and apply updates from the
distribution server as shown below.
This immediately updates the Virus Signatures.
