I still have release 220.127.116.11 and the firewall is giving me heart attacks, fits, frenzies and a MAJOR letdown, GROSS disappointment with ESET. I wrote to them and described in detail what my firewall problem was - megatons of these messages daily: Incorrect IP packet checksum Incorrect TCP packet checksum Detected ARP cache poisoning Identical IP addresses detected in network I even filled out one of the forms on the ESET site as well as several letters to Customer Support. That was over a month ago. Can you believe it? Not only am I very, very sad about the very poor customer support but I am out of my mind with worry about these entries in my firewall log - they're in bright red ink - a red flag if I ever saw one. It means pay attention, something is very wrong here, no? I very much would like to remedy this ASAP. I don't want to see these entries anymore, ever. I've already done the complete and total uninstall and reinstall. Makes no difference whatsoever. What to do? Can anybody who cares more that ESET please help or advise me? Thanks and have a great day!!!
