How Do I Uninstall the Agent?
If you no longer need to use HSS, uninstall its agent from your servers. After the agent is uninstalled, HSS will not protect your servers or detect risks.
Uninstallation Methods
You can uninstall the agent in either of the following ways:
- One-click uninstallation: Uninstall the agent on the HSS console. For details, see Uninstalling the Agent on the HSS Console.
- Manual uninstallation: Uninstall the agent on the server. For details, see Manually Uninstalling the Agent from a Server.
You are advised to uninstall the agent in one-click mode, simple and efficient. If the agent is in Offline state and cannot be uninstalled on the HSS console, you can manually uninstall it.
Prerequisites
When you uninstall the agent on the management console, the Agent Status of the server is Online.
