Modified Steam API files can compromise your Steam account credentials or trigger a Valve Anti-Cheat (VAC) ban.

: Security software frequently flags modified or even legitimate DLL files as malicious, quarantining them without your knowledge.

The legitimate version from Steam is not a virus. However, malware authors sometimes name their files steam_api.dll to blend in. Always trust the file that comes from Steam’s servers. If you verify integrity and your antivirus still flags it, submit a false positive report to your AV vendor.

Play Resident Evil 6 through the official Steam client with the genuine DLL intact. The game’s chaotic co-op is its best feature, and losing that for the sake of bypassing Steam is not worth the trade-off.
