Hi there, I know there are a couple posts regarding this issue the issue being: My ESS5 firewall is detecting threats of DNS cache poisoning attacks from i.p. 18.104.22.168 I looked up the IP and it belongs to Comcast which makes sense because I use comcast as my internet provider. I read a thread that said it is most likely a bugge in the firewall and ESET is working to fix it and that it is being detected as a threat whenever Comcast is pinging to see if my computer is still on the network. Is this true or should I be worried about my computers security? Also, I have already downloaded and run the DNS flush tool found on ESET's site. I flushed the DNS both times that these "attacks" were detected. Should I just continue flushing the DNS as it happens and are these legitimate threats or something similar to what I described above? btw, i have only had my computer for about 2 weeks, Eset for maybe 10 days, and today was my second detection. if it helps any, I am on windows 7/64 i believe and i have ESS5. Thanks for your help!
