Spybot - Search & Destroy includes a featured called Immunize designed to prevent spyware infection in real-time.
Please note: This feature enhances Spybot's protection against new spyware infections. You should still regularly run Spybot (ideally more than once a week) with up-to-date spyware definitions. See Running Spybot - Search & Destroy for instructions.

   From a security standpoint, any of these options are acceptable. Your settings should reflect your personal preference whether or not you would like to be notified of Spybot's automatic site-blocking activity.
8. Configuration is now complete. For best protection, Run Spybot - Search & Destroy at least once a week.
