  • You can select different protection for each of three different danger levels:
    • High Danger Level Spyware
    • Medium Danger Level Spyware
    • Low Danger Level Spyware

  • Prevent All - Select this option to detect, log, and prevent all attacks of this level.

  • Detect All - Select this option to detect and log only.
  • Log Redundancy Filter (Seconds) - To prevent the log from becoming overloaded with entries for the same attack, enter a value in the field. For example, if you entered a value of 30 seconds and there were 100 SubSeven attacks during that period of time, only one attack would be logged during that 30 second period.
