How to Fix “Some of your game files have been detected to have no signatures” in CS2
To fix “Some of your game files have been detected to have no signatures” in CS2, you need to verify the integrity of game files.
You can also try enabling/disabling administrator mode for CS2 or launch the game directly from your Steam Library.
Here are 3 methods to fix this:
Method 1 – Verify game files: Go to your Steam Library > right-click Counter-Strike > Properties > Installed Files > Verify integrity of game files.
Method 2 – Tick/untick admin: Go to your Steam Library > right-click Counter-Strike > Properties > Installed Files > Browse > right-click the Counter-Strike app > Properties > Compatibility > Tick/Untick “Run this program as an administrator”.
Method 3 – Launch in Steam Library: Open Steam > go to your Steam Library > launch Counter-Strike from your Steam Library.
Do note that the VAC error can be a temporary error that’s caused by a recent update.
If so, you need to wait for a new CS2 update to address the issue.
