Why is Easy Anti-Cheat untrusted?

Easy Anti-Cheat (EAC) is seen as "untrusted" usually due to the "Untrusted system file" error, which happens when EAC detects a Windows system file (like a .dll) that is corrupted, outdated, or lacks the expected digital signature, often because of a recent driver update or Windows build, creating a conflict that EAC flags as a potential cheat vector, requiring users to update Windows, verify game files, or manually replace the specific file.
