NOD32 AV v4 "Failed to read firewall configuration" Error

I have a user whose workstation displays this message upon booting into XP. I have deployed this same config to over 50 workstations and this is the only one. I have also tried installing fresh with no config and still get this error. The user is not an admin of the machine. I have tried uninstalling, re-installing, removing registry entries - nothing changes. Has anyone else had this problem and been able to resolve it? Thanks in advance for your help!

EDIT: BTW, this machine has never has SS installed on it, only AV.

 

Uninstall ESET and then do the following: (please note: some of these files/folders/drivers/ may not be there, which is OK)

Boot into Safe mode

1. Delete files and folder

Folders:
C:\Program Files\ESET
C:\Documents and Settings\All Users\Application Data\ESET
C:\ProgamData\ESET (vista)

Registry keys:
-HKEY_CURRENT_USER\Software\ESET
-HKEY_LOCAL_MACHINE\Software\ESET

2. Go to Window's Services and disable ESET Services
a. ESET Service
b. ESET Http Server

3. Go to Device Manager and disable drivers for ESET.

a. In Device Manager, go to View on the menu bar and select "Show Hidden devices". This opens up "Non-Pug and Play Drivers" in devices manager .
b. Disable "ehdrv" and "epfwtdir" drivers.

Boot back into normal mode and download "Windows Installer CleanUp Utility:

Run this program and make sure ESET is gone from the list.

Make sure you have the latest Windows Update and any other anti-virus program removed.

Reinstall ESET.

 

Thanks for the quick response, I will try it and report back as to how it goes.
