Steam is the most widespread and well-known platform for acquiring and collecting computer games, as well as for the game process itself. Naturally, in this case, the administration takes absolutely all measures to protect both the players themselves and the game servers. This is especially true of multiplayer games in which the concept of cheating is common. Gamers who are not able to defeat the enemy on their own enter special codes and install additional software in order to gain an unfair advantage over the enemy in an unfair way. In "Steam" there is a VAC system, which is an advanced anti-cheat that can track any signs of third-party interference in the game. If such activity is noticed, then the user immediately gets a ban not only in the game, but also his entire account. However, even if you are an honest gamer, you may have certain problems with this system - for example, many users receive an error with the message: "Your computer is blocking the VAC system." What to do in this case? There are several solutions, each of which you can try if the previous one did not work.
Restart and reboot
If your computer blocks the VAC system, then you will not be able to participate in all multiplayer games, as well as in those projects where this system is implemented by default. After all, your account will not be able to track the use of cheats, so you will not be allowed for security reasons. Therefore, you need to urgently solve this problem, and the first method, which in combination is the simplest one, is restarting the computer. To get started, you can just try to exit "Steam", and then start it again, but if this does not help, restart the computer. This can solve your small problem, if it is, of course, small. But if your computer is still blocking the VAC system after a reboot, then you need more drastic measures.
3rd party software
There are various reasons that your computer is blocking the VAC system, and one of the most common is a conflict with the software running on your computer. In most cases, it can be an antivirus or a firewall, but you should not think that these are only protective types of programs - other third-party software can also cause a similar error. Therefore, the best recommendation for you in this case is to turn off Steam, turn off all the programs that you do not need during the game, and then try to log into the server again. There is a high probability that the problem will not bother you anymore. But if your computer still blocks the VAC (CS: GO) system - what should I do?
Steam service recovery
The next way to solve the problem will look a little more complicated. It is suitable if there are any problems with the Steam service on your computer, which you can find in the platform folder (SteamService.exe file). And if your VAC system is blocked, then you should, by tradition, turn off Steam and then call the Windows command line . There you need to specify the path to the file indicated above and apply the / repair command to it. The process may take several minutes, but once it is complete you can play online again.
DEP
For those who are not very versed in computer technology, it is worth telling what this abbreviation means. DEP is a data execution prevention system that you need to activate in order to get rid of the VAC problem once and for all. To do this, you will again need to call the command line, but this time write bcdedit / deletevalue nx there.
