Hey Comodo,im writing you about this that in infected with RAT from my friend,which remain after reinstall of Windows and is undetectable by all av's .All i know that he is very experienced in hacking and he has written the virus.The problem is that i dont have the "virus file" with who i were infected.Hope you can inspect my system and make virus definitions and be the first who will discover it and protect your users.
May be he was just bragging and scaring you believing he infected your system?
