CSGO does not include any HWID protection or link accounts to each other. (Warning: SteamGuard (mobile+phone number) gonna link your account eachter so if you got a VAC/OW ban in one account other account gonna banned too.) So you don't need such software. If you still want to feel safe. You can completely remove Steam remnants and files by downloading the software at the link below. Other than that, I recommend restarting your computer after every cheat before logging into another account.
