Log on with local administrator privileges and navigate to Start > Control Panel > Uninstall a program (under Programs).

Select Websense Web Security / Websense Web Filter, then click Uninstall/Change.
This launches the Websense uninstaller.

On the Remove Components screen, select Filtering Plug-in and any other components to be removed, and then click Next.
4.
When the Stop Microsoft Firewall Service screen appears, stop the Microsoft Firewall service and then click Next.

Note 
Leave the Websense uninstaller running as you stop the Microsoft Firewall service, and then return to the uninstaller to continue.

The Websense ISAPI Filter has been unconfigured, you can now start the Microsoft Firewall Service.
