Multiple account on same PC

hi boys.. I want to use aimware hack on my pc but I have 3 accounts and I'm using the same pc for that.. so how can I play on the same pc using another account with hacks ..? 

I headed that steam ban all the account used on the same pc where hacks have been used.. need your suggestion what should i do.:D

That's wrong. VALVE bans only the account that you cheated on.

Best regards,

use a vm machine, your accounts will only get banned if they are linked via phone or email
