I installed trial of Panda security few days back, and sometimes when i go to internet , it gives me the following message. I wonder as far as I know spoofing means to cheat surfers by showing fake sites as original. I am surprized when I have just started surfing and I had hardly opened one site, how it is possible that I have got a spoofing attack. Also I have used NIS and Kerio before andf neither of them gave me any warning like this. Does this mean that they were not covering this thing. BTW, i do safge surfing and have not got any spoofing even without a firewall, as far as I think.
