"Cheat Engine v7.4 Portable by Devint" is a third-party modification of the popular Cheat Engine memory scanner, shared primarily through Telegram channels
A standard installation of Cheat Engine writes registry entries, installs drivers (for kernel-mode scanning), and leaves traces on your system. It also offers an optional "bundled" adware during installation (which many users mistakenly accept).

Risk of Bans: Using Cheat Engine—portable or otherwise—on games with active online components like Steam's VAC will likely result in a permanent ban.
