what is a loopback adapter & it's function? the IP address is 127.0.0.1
I had let things through into my "trusted zone" that I did not realize at the time was a bad thing. now I am trying to weed it out and leave the stuff that is ok. so is it good or bad for my computer?

127.0.0.1 refers to the computer itself. Hence a _loopback_. Note that isn't the actual IP used on the internet (can't have everyone using 127.0.0.1 !). Instead, it's a way of saying "myself" in terms of IP. What myself actually refers to obviously depends on who says it.
"so is it good or bad for my computer?"
Well, it isn't bad. You should leave it on because certain programs make use of sockets that listen on loopback (basically, it's a way of one part of the computer to communicate with another).

127.0.0.1 refers to your own computer, so you don't need to block it.
One function of a loopback adapter is to do a self-test of your network card. If you have network connection issues, it's a good way to troubleshoot the hardware to see whether the problem is with the network card itself. So as far as your firewall settings are concerned, just leave the loopback adapter free to do whatever it wants.
