Initiating Client Uninstallation

• Networked Computers > Client Management > Tasks > Client Uninstallation

Removing the OfficeScan client may expose the computer to security risks. Initiate client uninstallation only when there is an absolute need to do so, such as when client upgrade fails and you need to uninstall and then reinstall the client.

• Note: If the client also has a Cisco Trust Agent (CTA) installation, uninstalling the OfficeScan client program may or may not remove the CTA. This depends on the settings you configured for the client for Cisco Trust Agent deployment.

To initiate client uninstallation:

1. In the client tree, select the clients to uninstall and then click Initiate Uninstallation. The server sends a notification to the clients.

2. Note: If you do not select any client, OfficeScan automatically notifies all clients in the client tree.

2. Check the notification status and verify if there are clients that did not receive the notification.

1. Click Select Un-notified Computers and then Initiate Uninstallation to immediately resend the notification to un-notified clients. MORE >>

   Example

   Total number of clients: 15

   Client Tree Selection	Notified Clients (after clicking "Initiate Uninstallation")	Un-notified Clients
   No selection (all 15 clients automatically selected)	10 out of 15 clients	5 clients
   Manual selection (12 out of 15 clients selected)	11 out of 12 clients	1 client + another 3 clients not included in the manual selection

2. Click Stop Uninstallation to prompt OfficeScan to stop notifying clients currently being notified. Clients already notified and already performing uninstallation will ignore this command.

Using the client uninstallation program

If you granted users the privilege to remove the client program, you can instruct them to run the client uninstallation program. You can set this privilege in Networked Computers > Client Management > Settings > Privileges and Other Settings.

To run the client uninstallation program:

1. On the Windows Start menu, click Programs > Trend Micro OfficeScan Client > Uninstall OfficeScan Client.

2. Type the uninstallation password, and then click OK. OfficeScan notifies the user of the uninstallation progress and completion.

The user does not normally need to restart the client computer to complete the uninstallation. However, if you need to immediately reinstall the OfficeScan client after uninstallation and the installation package has a new version of a kernel mode driver, restart is necessary to unload the previous kernel driver version and load the new one.
