NOD32 V3with the ESS firewall, yes you read it correct. I uninstalled the ESS 621 in my Vista. I installed NOD32 V3 621 using my ESS serial number. The ESS firewall was in it. Uninstalled & restarted. I made sure it was the NOD32 I was installing. It was. This time I did not enter a serial number or password. In both installs I got this pop up evertime I went into the program in the sys. tray. "Failed to read firewall configuration" Does that firewall luv me or what, it's back.
