I have mcaffee firewall and anti virus. I like them and they allow LimeWire. When I install frostwire or something it doesn't ask to block or not but obviously it's working because people can download from me and I can download from other people. I am connecting from router. It's a U.S robotics. Also when I go to the monitor tab. It says i'm a leaf protected by an ultrapeer. Or something like that. I don't know much about how i'm connected. But I know i'm getting internet by a u.s robotics wireless router.
