Use BlackICE Defender to protect your PC from outside intrusion. The fine utility provides a solid firewall that detects, reports, and effectively blocks all access attempts. You shouldn't be without this type of security if you maintain a constant connection to the Internet via DSL connections and cable modems. BlackICE Defender offers four general security levels and allows you to easily add addresses to both safe and block lists. It runs quietly from your system tray, monitoring open ports. When an intrusion is detected, notification is provided by a flashing tray icon and an optional audio alert. Both the nature of the intrusion and the identity of the intruder are faithfully reported. Along with excellent documentation, BlackICE Defender provides detailed information about different types of attacks that actually serves as an Internet security tutorial.
