More and more games on Steam are starting to move towards multiplayer modes. Solo campaigns have long been replaced by exciting battles with your friends in different fictional universes. But the pleasure of online play is often disrupted by an error "Your computer is blocking the VAC system". Thousands of CS:GO and Dota 2 fans began to look for answers, what does it all mean? Why exactly can't I play? secure servers? It’s worth first understanding the principle of building online games.

VAC Block Notification

Let's first understand the VAC system. VAC program is a special security system for the entire gaming platform based on Steam. It was created with one purpose - to put players in the same conditions. This means that anyone who tries to use cheats will be banned. The ban does not only apply to the game Dota2 or CS:GO, the entire user account. The end result is the appearance of a message - “Your computer is blocking the VAC system. You cannot play on secure servers".

You can immediately hear many objections from honest players. It is logical to think that this cannot happen with a fair game, but in reality it is not so. VAC responds to all installed utilities on the computer. If at least one program causes concern, then you should expect blocking. The fault may also be viruses. Their activities affect not only the PC, but also the work of Steam.

Reasons for account blocking?

The obvious answer is fair game. There is no need to look for ways to deceive the system for millions of dollars, on which the best IT specialists of the company worked Valve. In 90% of cases everything will be revealed. Show respect for other players and start thinking more with your head so that your battle statistics have a positive trend. Other reasons for a ban include:

1. Systematic shutdown games during battle;
2. Numerous complaints from other players;
3. Creation fixed matches between opposing teams;

Steam algorithms monitor all unnatural actions of players and immediately block the player.

Valve has officially informed players about the presence of such security measures. Therefore, in solving the blocking there are methods from both officials and ordinary players. Each method is effective in its own way.

1. To start restart your PC and router or network settings and try to start it.
2. Try running the Steam client from under administrator.
3. There may be a conflict with drivers - boot your PC via F8 and select the option to disable driver signature verification. We launch it, if it works, update the drivers.
4. Visit official page Steam- provides comprehensive information about the problem of blocking by the VAC system. Pay special attention to the list unwanted programs that need to be disabled while Steam is running.
5. Support. Write to Steam Support from your account. Explain the situation in as much detail as possible. Tell us your sequence of actions before blocking VAC. Perhaps there were interruptions in the Internet and therefore exits from the game occurred frequently. The main thing is to show sincerity in communication.
6. If the error occurs while playing Dota 2 or CS:GO, try change servers.

In this article I will tell you how you can solve this problem, and also explain where it actually comes from.

So, let's imagine this situation: you launched CS:GO, tried to log into the server, but the system gave you this error. Don’t be alarmed, the error tells the user that “Steam” cannot use virtual and RAM, and it should be noted that everything is fine with your account.

What is VAC and what is it for?

This abbreviation stands for “Valve Anti-Cheat”. Valve has taken the fight against cheaters seriously and has developed its own protection system. The module is built into Steam, so players do not need to download separate software. VAC works in such a way that a block is installed on the game where the prohibited program was detected.

Instructions for fixing the problem will be relevant only for those users who did not use cheats to play CS:GO. If VAC detects prohibited software, then you will be denied access to official servers protected by anti-cheat. If the program has found cheats, the following message will appear:

Your computer is blocked by the VAC system, due to violations you are prohibited from playing on secure servers.

How to get rid of the error when we see that the computer is blocking the VAC system?

First way

The error we are looking at appears due to incorrect operation of the operating system. You can try to solve the problem as follows:

You must exit the game and the Steam application completely. To do this, you need to close all processes in the Task Manager. Read more about all the tricks about the task manager here.

In general, select Steam and click “End process”, as shown in the screenshot:

Now go to the “Start” menu, go to the “All Programs” section. Find “Standard” and select the “Command Line” tool. You need to run the line as an administrator (right-click on the icon and select the appropriate item). In the latest versions of the Windows operating system, the command line can be opened by pressing the key combination “Win ​​+ X”.

Enter the following command there and press Enter:

"bcdedit.exe /nx deletevalue"

After completing this step, the computer must be restarted. Try launching CS:GO again and logging into the server. Quite often this simple action helps solve the problem.

The second way to get rid of the error

The notification appears every 10-15 minutes. Sometimes the first instruction gives a positive result, but the error pops up again after 10-15 minutes. This problem also has a solution:

— Exit the “Steam” application and CS:GO itself, as indicated in the first step of the previous instructions.

- Using the key combination “Win ​​+ R”, call the “Run” tool.

— In the line that appears, you need to enter the command: “C:\Program Files (x86)\Steam\bin\SteamService.exe”/repair

- After this action, you also need to restart the computer.

Done, the game should work fine after making changes to the system. If this does not help, then the only option is to reinstall the operating system. Install a new Windows and download the latest drivers. This will definitely solve the problem.
