VAC is an automated software system installed on users' computers to detect cheats. It is developed by Valve as a part of the Steam platform. The system identifies fraud using cheat signatures.
Any third party change (cheating) that makes a player superior to another player triggers the ban system. This category also includes changes to the game's dynamic link libraries and executable files.
Game bans will be expanded to VAC bans if the user is caught by this system. The system ban can be given for more social games that use the same platform. As a result, if the player gets caught for cheating in any source games, he will get banned from Day of Defeat: Source, Team Fortress, Counter-Strike: Source and Half-Life 2: Deathmatch games.

Updated system drivers, like video card drivers
Prohibitions are permanent, non-negotiable, and cannot be removed. If the ban is judged to be an error, it will be removed automatically.
To avoid a ban, the players should only connect to VAC-protected servers from trusted devices. Therefore, users should never play on anti-cheat protected servers if they are not sure whether the software they use has cheated or not. It is crucial to be careful when loading files that make changes to games, like custom views. Players should download the content only from trusted sources.
