Solved: 'Some of Your Game Files Have Been Detected CS2' Error - My Experience and Fixes

As a CS2 player, I recently encountered the frustrating "some of your game files have been detected" error.

This message prevents you from joining VAC secure servers, essentially locking you out of the game. After trying various solutions, I want to share what worked for me and other players in the community.

First, let's understand what causes this error.

It often occurs when the game files aren't properly signed or verified by VAC (Valve Anti-Cheat). This can happen for several reasons, including how you launch the game or where it's installed.

Here are the solutions that have worked for many players, including myself:

1. Launch from Steam Library: Always launch CS2 directly from your Steam library. Avoid using shortcuts, especially those created from the cs2.exe file. I found that my taskbar shortcut was the culprit.
2. Verify Game Files: In Steam, right-click on CS2, go to Properties > Local Files, and click "Verify integrity of game files." This process can fix any corrupted or improperly signed files.
3. Run Steam as Administrator: Try running Steam.exe as an administrator. For some players, this solved the issue immediately.
4. Reinstall on C Drive: If you've installed CS2 on a different drive, try moving it to your C drive. This worked for several players in the community.
5. Avoid Network Transfer: If you use Steam's network transfer feature to install games across multiple PCs, try a direct internet install instead. The network transfer can sometimes cause file signature issues.
6. Remove Admin Rights: Conversely, some players found success by turning off "Run as Administrator" for CS2.

If none of these solutions work, you might need to try a clean reinstall of CS2.

Make sure to completely uninstall the game, delete any remaining files in the installation folder, and then reinstall fresh from Steam.

Remember, the "some of your game files have been detected" error can be tricky, and what works for one person might not work for another.

Don't get discouraged if the first method doesn't solve your problem. Keep trying different solutions, and you'll likely find one that works for your specific setup.

Lastly, always keep your game and Steam client updated. Valve regularly releases patches that can fix these types of issues.

I hope this guide helps you get back to playing CS2 without any VAC errors. Good luck, and I'll see you in the game!
