Uninstall a Nessus Agent on Windows

Before you begin:

• Unlink the agent from the manager.

To uninstall Tenable Nessus Agent from the Windows user interface:

1. Navigate to the portion of Windows where you can Add or Remove Programs or Uninstall or change a program.
2. In the list of installed programs, select the Tenable Nessus product.

3. Click Uninstall.

   A dialog box appears, prompting you to confirm your selection to remove Tenable Nessus Agent.

4. Click Yes.

   Windows deletes all Nessus related files and folders.

   Note: On Windows, the Tenable Nessus Agent uninstall process automatically creates a backup file in the %TEMP% directory. If you reinstall Tenable Nessus Agent within 24 hours, Tenable Nessus Agent uses that backup file to restore the installation. If you want to reinstall Tenable Nessus Agent within 24 hours without using the backup, manually delete the backup file in the %TEMP% directory beforehand.

1. Open PowerShell with administrator privileges.

2. Run the following command:
