Well I'm feeling quite paranoid now...
I have no idea what half the stuff you guys talked about is.
I use MiamiDx, IBrowse, YAM, DOpusFTP, occasionally AmIRC (very unstable), over a 33.6 modem connection.
I don't have AWNPipe installed though.
I'm pretty much a novice at the internet (you'd probably noticed), should I be worried about this stuff? Should I be using a firewall, and how would I set one up?
How does one avoid using FTP?
