(WITH V SERVER) (WITHOUT SEE 1A)
1. First of all we need pretty much any windows, preferably windows 7.
2. Then we need bought or cracked WORKING Sandboxie.(Like Avast Sandbox or Sandboxie)
3. 9 to 10 csgo accounts.
4. ANY cheap VPS server.
5. We create 10 sandboxies, on each sandboxie we setup 1 csgo account with starting parameters:

novid -w -safe -noaafonts -nosound -threads 1 -console

6. We set lowest possible graphic settings.
7. We set ping limit to lowest.
8. Once we have everything ready in lobby, we do start the game normally.
9. All we need to do now is start the game normally.
10. FIX TIME !
10a. So we bought the VPS, right?
Now we will install Hourboosterv2 into it. After successful installation, we add all accounts into it. We install fillezilla, we set the restart limit to 9000 in configs and we are done.
10. We start the hourbooster once we are in the first game not before and then we just keep it running until the end of the boosting session.
11. Good job! You just fixed vac error in csgo.

1A. Download Avast Sandbox and add your Steamaccounts too Avast.
2A. Then use Vpns too find better. Like VPNS for Brazil or something
3A. And then search! GOOD LUCK ;D
