vac authentication error CS:GO

[alvin]

Hello, my friend is having issues with a weird error. He keeps getting "vac authentication error" randomly in match.

He tried so far:

• Reinstalling CS:GO
  
• Repair steam service
  
• sfc /scannow in CMD
  
• Verify files
  
• Restart PC
  
• Restart Steam
  
• Turned off the anti-virus and majority of applications

Is there a solution to this problem? It is really annoying, plus he gets banned unfairly

[Coś ci to przypomina?]

Ayo he's vac banned

Vac ban is permament, he can't be unbanned

He just played a match with me, he randomly gets that error throughout the match. It's not the only time it has happened.

OP, your friend got a 3rd party program that is being flagged by CS:GO VAC Secure Servers System.

thus as a result, he got VAC Error.

and do not listen to "crystal meth" posts at all.

he don't even know the difference between VAC Ban and VAC Error at all.
