ok, newbie question. i'm 90-100% sure that i had a trojan on my system before. i have since then formatted, but i'm not sure if that is adequate. i've ran several anti-trojan/cleaning programs, and each of them came up with nothing, but if the person i got it from wrote his/her own code, this would mean nothing, correct? my cable l.e.d. for activity runs pretty consistently, and i'm not sure what kind of background noise this could correspond to. any help would be much appreciated.

--also, how do i get netstat to keep the window open. when i run it the window pops up and then disappears before i can see anything.
