Hello, I currently run Nod32 EAV for windows xp sp3 and windows xp pro 64 bits (dual boot). ZoneAlarm pro runs on the 32 bits OS and Outpost 2009 pro (trial) on the 64 bits OS. All is fine but my licence ends on October 13. I hesitate between renewing my licence or go to ESS v4. 1) Can ESS replace my current firewall ? 2) Is ESS firewall easy to use ? 3) Is ESS firewall as good as ZA Pro or Outpost ? Thank you for hints.
