not sure if infected

[itachi]

i am not sure if my machine is infected, RogueKiller found a infected registry key i think and Emsisoft Emergency Kit. found 2 threats but i freshly installed windows(to fix my illegal windows 7 that i wasnt aware of so i fixed that i hope i can still ask support after that otherwise i am sorry to bother you) so i hope we can find out if my pc is infected and if so clean it
