I use NOD32 as my antivirus and Zone Alarm Free as my firewall. I have NOD32Krn.exe (the program that gets updates) in the trusted zone. I also have all 3 of my DNS servers IP addresses in the trusted zone. Last night, NOD32krn.exe was blocked from accepting a connection from the local zone 3 times (once from each DNS server). Is this normal even though I have NOD32 and the DNS servers in the trusted zone? Do I need to give NOD32 server access in addition to internet access?
