i just built a new computer and an attacker has a keylogger in 1 day. now i've reformatted, scanned several times in safe mode with several anti-virus programs (nod32, avg, zone alarm,a-squared, trojan hunter, trojan remover, now i'm trying aatools) but they all scan clean. my attackers either got in again or the virus is still there. i don't think are experienced. can someone please tell me what my other options are for getting rid of my keylogger and suspected trojan?
