Been using Nod32 and Comodo Firewall with no problems... so I decided to give Comodos Antispam product a try. After I installed it... Nod32 now says (everytime I boot the computer): "The network configuration was changed and IMON has updated the necessary settings accordingly. For changes to take effect, please restart the computer." Does that mean these the antispam and nod32 do not play well together? Everything seems to work...but I have only been testing it about 2 hours. Thanks, Tony B.
