ESET says the firewall is active fine, but a couple of times I've received at error message that it couldn't detect firewall configuration or something. The last time was when I added firefox to the exclusions list for from protocol filtering(was doing a speedtest). I had just run some commands(netsh nt ip, netsh winsock) and restarted my computer before I did this. Windows XP Professional 32bit Linksys Wireless-G PCI Adapter - WMP54g (connection to router) My ethernet card (Atheros PCI-E Ethernet controller) is disabled. I didn't have this problem with 4.0.437, only since I updated(new OS install, no previous antivirus) to 4.2.40. I decided to disable the ethernet card then(so already disabled before I ran the netshell commands), this wouldn't be a problem would it, if it isn't used?
