Help I have a question and am planning to buy

So I have had a long time question see I have a main account that has lots of skins but I never cheat or have anything injected. I don't want to get gamebanned on that account is there any chance that vac scans my hard drives and see aimware that I use on other accounts and get banned on main.

No, we're doing something so we avoid VAC perfectly fine, you won't be banned by VAC on the account you cheat on or on your main. (if you get game banned aka overwatched you'll just be banned on the account you injected on)
