The cs2-untrusted error in Counter-Strike 2 means Valve's anti-cheat system (VAC) or the game's integrity checks have flagged your connection or game files as untrusted, causing you to be kicked from the server. This can happen due to corrupted game files, third-party software interfering with CS2, outdated drivers, or a compromised game installation. The good news is that in most cases this is not a ban — it is a temporary flag that can be resolved by following the steps below.

Tools You'll Need

How to Fix Error Code cs2-untrusted

  1. Restart Steam and Counter-Strike 2

  2. Verify Integrity of Game Files

  3. Close All Third-Party Overlays and Injectors

    Do NOT use any third-party cheat software, aim-assist tools, or game-modifying programs. These will trigger VAC bans, which are permanent and cannot be appealed.

  4. Disable Steam Launch Options That May Conflict

  5. Run Steam and CS2 as Administrator

  6. Update or Roll Back GPU Drivers

  7. Check for VAC Service Issues and Restart the VAC Service

  8. Temporarily Disable Antivirus and Windows Defender

    Only disable antivirus temporarily for testing. Re-enable it immediately after your test session.

  9. Clear the Steam Download Cache

  10. Reinstall Counter-Strike 2

When to Call a Professional

If you have followed every step above and are still receiving the cs2-untrusted error, your Steam account may have received a VAC ban or a game ban. Check your Steam profile at steamcommunity.com — if a ban is listed, it is permanent and cannot be reversed by Valve support in almost all cases. If your account shows no ban but the error persists, contact Valve Support directly at help.steampowered.com with a detailed description of the issue and any error logs. A professional PC technician can also help if you suspect a rootkit, malware, or deep system-level conflict is causing third-party code to interfere with CS2.

Frequently Asked Questions

Does the cs2-untrusted error mean I am VAC banned?
Not necessarily. The cs2-untrusted error usually means the game's integrity check failed temporarily, often due to corrupted files, a conflicting program, or a network issue. A VAC ban is permanent and will appear as a badge on your Steam profile. If your profile shows no ban, you are not VAC banned and the error can typically be fixed using the steps in this guide.
Why do I keep getting kicked with the cs2-untrusted error after every match?
If the error is happening repeatedly, the most common culprits are a background program with an overlay or memory-injecting feature (such as Discord overlay, RTSS, or MSI Afterburner) that is running every time you launch the game. Go through Step 3 in this guide carefully and disable all overlays and monitoring tools. Also run a full file integrity verification through Steam.
Can third-party software like Discord or OBS cause the cs2-untrusted error?
Yes. Software that injects code into running processes — including Discord's in-game overlay, OBS with game capture mode, RTSS, and similar tools — can trigger CS2's untrusted flag. Disabling overlays in these applications (rather than closing them entirely) is usually enough to resolve the conflict.
Will reinstalling CS2 fix the cs2-untrusted error?
In many cases, yes. A fresh reinstall eliminates corrupted or tampered game files that cause the untrusted flag. However, if the root cause is a conflicting background program or a system-level issue, reinstalling alone will not help — you also need to address the software conflict by following the steps in this guide.
How long does the cs2-untrusted kick last?
The cs2-untrusted kick is not a time-based cooldown like some other game errors — it will continue to happen every time you launch into a match until the underlying cause is fixed. There is no waiting period; you need to resolve the root issue (corrupted files, conflicting software, etc.) using the troubleshooting steps above. Once fixed, you can rejoin matches immediately.
