If you found csgocheat.dll on your computer and didn't put it there:

Files like csgocheat.dll are (DLLs) used to modify the code of Counter-Strike while it is running. These files are typically injected into the game's memory to enable unauthorized features like wallhacks or aimbots. ⚠️ Critical Security & Safety Risks

The Valve Anti-Cheat (VAC) system and VAC Live for CS2 scan for these specific injections. Using them will lead to a permanent account ban and a loss of all in-game skins.
