Hey!
I set up on one PC, installed zonealarm, set up another one, put zonealarm to think that the other PC is the internet, and ran a few test.....
N-Stealth - Gets to test #2100 then the HFS crashes, and brings down the rest of the PC (tired it twice)
tho the top10 and top20 option - cant break in!
at the mo downloading another bit of software to see if that can do any damage!
