Help Removing Hacks

i have a question

Is there any way to remove hacks from your regisrty so when ppl teamview you and go into the registry files they dont see anything i have hacked previously but stopped now ppl have been reporting me and i got my csm 5 banned...

Now i made a new acc deleted all the hacks but ppl still find the files..

i know on mpgh there was some program or something but i'm gonna ask you cause you know alot about hacks..

Thanks XD
