VAC bans are final, non-negotiable, and cannot be lifted by Steam Support.

If you are mistakenly subject to a VAC ban, it will be lifted automatically. If you would like to discuss the VAC system with the Steam community, you can do so.

FAQ:

What is VAC?

VAC (Valve Anti-Cheat – Valve Anti-Cheat) - automated system, created to detect cheats on user computers. If a user connects to a VAC protected server from a computer that has recognized cheats installed, they will be VAC banned and will no longer be able to play that game on VAC protected servers.

The VAC system reliably detects cheating programs based on their signatures. Any third-party changes to the game made by the user to gain an advantage over others are classified as cheating or hacking and will result in a ban by the VAC system. These changes include the replacement of executable files and dynamic link libraries.

Administrators of a particular server can block a specific player, but they cannot block a cheater using the VAC system.

The following actions Not lead to blocking by the VAC system:

• Using chat programs similar to X-Fire or Overwolf
• Configuration hardware
• Updating system drivers such as video card drivers

How can I avoid VAC ban?

To avoid the possibility of your account being blocked, use only trusted computers to play on servers protected by the VAC system. If you cannot tell for sure whether any cheats are installed on the computer you are using, refrain from playing on secure servers.

Be vigilant when installing any modifications, such as scripts or custom skins. Only download user-generated content from trusted sources. Hackers can maliciously disguise their cheats as modifications to get other users banned.

For more information about protecting your account, see Account Security Best Practices.

Additional Information Valve's guidelines can be found in the Steam Subscriber Agreement.

If I am VAC banned, what does this mean for my account?

For detailed information on how a VAC ban affects your account, please refer to the article.

How do I notify Valve about a new cheat?

If you have information about new cheat programs, especially private ones (not available on public websites), and you can provide links to them or yourself executable files, please send an email with all information to:

All letters will be reviewed by the staff responsible for developing the VAC.

How to report a cheater?

If you think that there was a cheater in the game with you, please report it to us and follow the instructions in the article.

Note: The VAC system does not block users based solely on complaints. Other factors are also taken into account when deciding whether to block a user.

What games are VAC protected?

A list of VAC-protected games can be found in the Steam store at the following link.

If I'm blocked, can I play on unprotected servers?

Yes, if the game provides such an opportunity.

Some VAC-protected games allow the existence of servers that are not protected by VAC. Blocked users can still play on unprotected servers of the game in which they were blocked for cheating. Please keep in mind that not all games have unsecured servers.

Will I be harmed if someone I share my game library with cheats?

What is the difference between a server ban and a VAC ban?

A VAC ban makes it impossible to play on all protected servers on Steam, while server admins can ban someone on their servers, but this is not as serious as in the case of VAC. Valve cannot prevent bans on user servers. The server owner has the right to block any player for any reason.

If you find yourself banned from a large group of community servers, it is likely that you were banned by a third party system such as Steambans or Punkbuster. These third-party systems are used by multiple servers and share a common database of banned players. These systems are not associated with Steam in any way, and we cannot help you with issues related to them.

You will only be VAC blocked if you connect to a VAC-protected server from a computer with cheat programs installed.

What to do if your computer blocks the VAC system in CS GO and other games? The answer is simple - try to fix it. Let's try.

Solution 1: Solving the VAC blocking problem

Running the command line in Windows 7:

Click the button and in the bottom search bar start typing the word cmd

When the program shortcut appears at the top of the menu, right-click and select Run as Administrator.

Launching the command line Windows 8, 10:

Press the + key combination and select Command Prompt (Admin) from the pop-up menu

bcdedit /deletevalue nointegritychecks

bcdedit /deletevalue loadoptions

bcdedit /debug off

bcdedit /deletevaluenx

Something like that:

It is worth considering that when executing these commands, the system may produce errors (shown below in red) - THIS IS NORMAL.

This only means that the options that we are trying to remove are already missing, which is also not bad for us, in principle.

Now, you just need to restart your computer.

Solution 2: Incompatible programs

The Steam documentation contains a list of programs that may conflict with the platform. Here is a small list of them.

• Cheat Engine
• IObit Start Menu 8
• CCleaner
• Process Hacker
• DLL Injectors

You should get rid of them, or you can simply exclude them from the startup list. Paradoxical as it may seem, it is better to do this procedure using CCleanera itself.

Solution 3. Unofficial.

Based on the previous solution, we will do away with the official recommendations from Steam and move on to “folk art”.

On our two test computers on which vac was blocked, with Windows 7 and Windows 10 operating systems installed, none of the above methods worked. The third method helped, which we will share with you below.

The initial steps are the same as in the first solution, only instead of those four lines, you only need to enter one:

bcdedit.exe /set (current) nx OptIn

After that the games started working. Minecraft also worked, which produced the following error on a computer with Windows 10:

But after 40 minutes of play, he showed it again. Let's figure it out - we'll write.

Your computer is blocking the VAC system - what to do?

"Steam" is the most widespread and well-known platform for purchasing and collecting computer games, as well as for directly gameplay. Naturally, in this case, the administration is taking absolutely all measures to protect both the players themselves and the game servers. This is especially true for multiplayer games, where the concept of cheating is common. Gamers who are unable to defeat the enemy on their own introduce special codes and install additional software to gain an unfair advantage over the enemy through dishonest means. Steam has 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, the user immediately receives a ban not only in the game, but also in his entire account. However, even if you are an honest gamer, you may experience 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 take part in all multiplayer games, as well as in those projects where this system is implemented by default. After all, your account will be impossible to track for the use of cheats, so you will not be allowed for security reasons. Therefore, you urgently need to solve this problem, and the first method, which is also the simplest, is to restart the computer. To begin with, you can simply try exiting Steam and then launching it again, but if this does not help, restart your computer. This may solve your small problem, if it is small, of course. But if your computer still blocks VAC after a reboot, then you need more drastic measures.

Third party software

There are various reasons why your computer is blocking the VAC system, and one of the most common is a conflict with software running on your computer. In most cases, this could be an antivirus or firewall, but don't think that these are only security types of programs - other third-party software can also cause a similar error. Therefore, the best recommendation for you in this case would be to turn off Steam, disable all programs that you do not need while playing, and then try to log into the server again. There is a high probability that the problem will not bother you again. But if your computer still blocks the VAC (CS: GO) system, what should you do in this case?

Restoring the Steam service

A little more complicated will look next way solving the problem. It is suitable if your computer has any problems with the Steam service, which you can find in the platform folder (SteamService.exe file). And if your VAC system is blocked, then you should, according to tradition, turn off Steam, and then call the command Windows string. There you need to specify the path to the file indicated above and use the /repair command on it. The process may take a few minutes, but once completed you will be able to play online again.

DEP

For those who are not well versed in computer technology, it is worth telling what this abbreviation means. DEP is a data execution prevention system that you need to activate to get rid of your VAC problem once and for all. To do this you will again need to call command line, but this time write bcdedit /deletevalue nx there.

Your computer is blocking the VAC system - Articles and help

When playing on DotA 2 or CS:GO servers, you are not allowed into the server? This error does not tell us that the account is blocked, it only tells us that the steam application and all its processes are unable to use the computer’s RAM and virtual memory properly for normal operation.

Let's first understand the terminology and probable reasons, before offering hackneyed solutions from the Internet.

If VAC does not work, but the account is not clearly banned, the problem lies in the OS itself, the PC settings.

So what is VAC and how does it work?

VAC - Valve Anti-Cheat, this anti-cheat, developed by Valve, is a server protection module against cheats, it is distributed between game clients through a secure VAC server channel. That is, players do not need to download third party software, and install it additionally to the game. If a new VAC module appears, the servers automatically download the update and install it in background. This is very convenient, since you don’t need to update with a key, or keep admins up to date with the latest patches. So VAC is the main licensed version of anti-cheat for your server.

During early testing in 2002, some material about the program was made available to the public through the HLDS mailing list. The anti-cheat could detect OGC - OpenGL Hack, OpenGL-based cheats, as well as CD key spoofing. Information about identified scammers was sent to the blacklist server at IP address 205.158.143.67 with port 27013. There is also a Master Ban List server. Its port was later changed to 27011. Errors system memory and hardware may kick the player out of the game, but do not block his access. In this case, the VAC module is loaded into the memory of the user's PC and ensures that extraneous processes do not interfere with the game. Virtually any program that intrudes into the address space running process games can be regarded as a cheat. The VAC system currently uses the UDP port range 26900-26999 for monitoring. For selection specific port scan, enter the launch parameter in the application: steam.exe -steamport 26950 (for example). Therefore, the steam user’s computer must have an appropriate range of ports open for incoming connections and not be blocked by antivirus software or all kinds of firewalls and system defenders.

Having detected outside interference that fits the definition of a cheat, the VAC module reports this to the central VAC servers at Valve. Detailed information about the type of intervention, account information, etc. is also sent there. When information about a violation is received on the VAC servers, a “cheater” flag is set in the record of the violating account in the central Steam database and a countdown starts (usually from a week to two months), after which the flag changes to “banned” and the account is denied access. access to any servers protected by VAC.

The following actions are not blocked by the VAC system:

• Using chat programs such as X-Fire.
• Hardware configuration.
• Updating system drivers, such as video card drivers.

As mentioned earlier, access to VAC-protected game servers is lost. The block is only applied to the game where cheating was detected, with some exceptions:

• If a cheat was detected in one of the games on the GoldSource engine (for example, Counter-Strike 1.6), then all games on the GoldSource engine (Counter-Strike 1.6, Team Fortress Classic, Half Life Deathmatch, Ricochet, etc.) are subject to blocking;
• If a cheat was detected in one of the following games: Counter-Strike: Source, Counter-Strike Global Offensive, Team Fortress 2, Day of Defeat: Source, Half-Life 2: Deathmatch, then the blocking applies to the entire list of these games

The best indicator that you are VAC blocked is that you receive the following message when you try to access a VAC-protected server:

"Trying to join this server was rejected. Due to previous violations, you are prohibited from playing on all secure servers."

If you see a cheater on the server, no matter how openly he cheats, he will not suddenly be thrown out of the server with the message “VAC banned.” This mechanism is made so that cheaters cannot find out with any certainty whether a particular cheat is caught by VAC or not. Direct protection of the game from cheaters, as before, lies with the admins. VAC2 will never ban you for various kinds scripts, models, skins, etc. All this does not fall under the definition of "cheat" from a VAC point of view. However, you may be banned for having programs that invade the memory of the hl2.exe/csgo.exe/dota.exe etc. process. Here there are obvious cheats, various programs to speed up Windows operation", any programs that intercept information from video drivers, and so on. Be careful with the programs you install!

If you are banned by VAC2, your chances of being unbanned are zero. Valve has detailed information about why exactly you were banned, and you won’t be able to get unbanned through the support service.

• Don't use cheats (!!!)
• Use a clean, original Windows OS image.
• If possible, use the licensed version operating system or switch to Linux.
• Do not use suspicious operating system image builds or cracks to activate it that you know nothing about.
• If you use a firewall or antivirus, DEP, UAC, add games and the steam application itself to exceptions or disable them altogether. Open the appropriate ports, if they are closed, for steam and games to work correctly.
• Do not use software you know nothing about to “boost” and speed up your computer.
• Use only fresh and original drivers for the system and video card.
• Do not use Russian letters in the path to the steam application and games during installation.
• Do not forget to update the games and the steam application itself, if possible, run it as an administrator. After updates, restart the steam application before you start playing.

1) Exit the game, from Steam, close it in the Task Manager running applications steam 2) Go to the start menu => All programs => Accessories => Command Line (Right-click on the icon and select “Run as administrator”). On Win8, call the command line using Windows + X 3) In the command line, enter bcdedit.exe /nx deletevalue , press Enter 4) Reboot the computer 5) Try to play.

If the notification still pops up after 10 minutes of playing, then do this:

1) Exit the game, Steam and exactly the same as in point 1 of section 1 2) Call the command line using Windows + R 3) Enter this => "C:\Program Files (x86)\Steam\bin\SteamService.exe "/repair 4) Reboot the computer

Your computer is blocking the VAC system

Left the game. Clicked exit Steam. It says that CS GO is running (it wasn’t even hanging in the processes) and therefore it is impossible to exit Steam. Disabled all Steam processes. Launched the command line as administrator. Entered "bcdedit.exe /set (current) nx OptIn". Operation was successfully completed. Rebooted. Launched Steam. I went into CS GO: again “Your computer is blocking the VAC system.” Then they gave me a block for 7 days. I waited. I went into CS GO. Started playing competitive mode. After about 5 minutes it throws it out and writes “Your computer is blocking the VAC system.” I repeat the above steps. Then again the competitive mode is blocked for 7 days. What should I do? Unfortunately, my conscience and laws do not allow me to describe the beauty of the situation. p.s. This isn't even the 10th time this has happened. Windows 10 64 bit.

VAC Authentication Error or Your computer is blocking the VAC system

Sometimes you play competitive mode in CS GO and at some point you get the error “Your computer is blocking the VAC system. You cannot play on protected servers” and you cannot reconnect to the server. As a result, you are banned for not being able to connect within a short time.

The answer is simpler than ever. The main thing is to do all the actions very quickly, so as not to be caught by a temporary ban in MM. For convenience, add this page to your favorites so as not to lose it. And so let's get started.

This is a simple way to get rid of this error.

If these manipulations did not help you, then clear the contents of the cache folder, which is located: Steam\steamapps\common\Counter-Strike Global Offensive\csgo\cache

Have you often encountered the “” error right during a competitive game? Are you running out of patience because of receiving bans related to this particular error? Below we have compiled a small list of actions, following which you will definitely get rid of the error “ You cannot play on secure servers” and you can safely continue playing MM.

The VAC error most often occurs due to changes to game files and/or textures.

How to fix the error “Your computer is blocking the VAC system”?

1. Quit STEAM;
2. Click “START” -> “Run”.
3. In the small window that opens, enter: “C:\\Program Files (x86)\\Steam\\bin\\SteamService.exe” /repair
4. After entering the command, scanning of STEAM files will begin.

NOTE: Verifying the files may take some time, so please be patient and just wait. If you installed STEAM in a different folder, replace C:\\Program Files (x86)\\Steam with your path.

3. Restoring the settings of the “Kernel Integrity Monitor”, “Kernel Debugger” and “Data Execution Prevention” systems.

These systems must be in a “standard” form. Let's try to return all the settings to default.

To restore all settings to default, you must:

1. Quit STEAM;
2. Click “START” -> “Run”.
3. Enter “ cmd” (without quotes). A black Administration console will open in front of us.

3. In the console, enter the command “ sfc /scannow” (without quotes) and press Enter:

When the file scan is finished, restart your computer.

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 you should definitely note 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 operating system Windows systems The command line can be called up 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. Put new Windows and download the drivers latest version. This will definitely solve the problem. I also suggest you watch the video: how to get rid of the error your computer is blocking the vac system.

To summarize today’s article “Your computer is blocking the VAC system”, it will be necessary to make several additions. To fully use Steam and CS:GO, you must adhere to simple tips:

- Play without cheats.

- Don't use pirated assemblies operating system.

— Do not install software on your computer to improve hardware performance. It is recommended to run each downloaded file through an antivirus.

— Update the drivers for the video card - this is the main component of the computer responsible for the quality of video games.
