Hi all, I'm using zonealarm. After I installed and uninstalled a packet sniffer (using WinPcap, I think), I decided to manually permit programs to access internet each time, in order to see the IP they are trying to connect. Problem is, IE (or other browsers) are now trying to access 127.0.0.1 before every connection and if I don't allow, I can't connect anywhere (Outlook expess and Cute FTP does not do this, however). I'm not sure when this started, it could be after XP service pack2 or some security update, or the packet sniffer may have brought a virus. I'd appreciate any suggestions. Thanks a lot..
