Antivirus

Hey! Question: the antivirus swears at trainers for games, how to make sure that you don’t pick up a real antivirus from trainers? Is it possible to somehow localize a partition on a disk for games with trainers, and wrap this partition in some kind of container, so that in the event of a virus, the computer would not be damaged, except for this partition?
