     Do not run the uninstallation command in the /usr/local/hostguard/ directory. You can run the uninstallation command in any other directory.

     • For EulerOS, CentOS and Red Hat, or other OSs that support RPM installation, run the rpm -e hostguard command.
     • For Ubuntu and Debian OSs, or other OSs that support DEB installation, run the dpkg -P hostguard command.

     If information similar to the following is displayed, the agent has been successfully uninstalled. If the uninstallation fails, go to the step 3.

       2. Run the following command to check whether there are hostguard processes:

          If there are residual processes, run the kill -9 PID command to stop all residual processes.

       3. Run the following command to check whether the /usr/local/hostguard directory exists:

          ll /usr/local/hostguard

          If the directory exists, run the rm -rf /usr/local/hostguard command to delete it.

       4. Run the following command to check whether the /etc/init.d/hostguard file exists:

          ll /etc/init.d/hostguard

          If the file exists, run the rm -f /etc/init.d/hostguard command to delete the file.

     • For OSs that support DEB installation, such as Ubuntu and Debian.
       1. Run the following command to check whether there are hostguard processes:
