How to close Internet access on your computer. How to prevent applications from accessing the Internet on Android

Some programs can independently access the Internet in order to download updates or send some statistics. In this lesson we will learn how to block Internet access to certain programs.

The program accesses the Internet in background, so the user may not notice this process.

Step 1: Windows Firewall

First we need a windows firewall. For this we go Start – Control Panel – Windows Firewall:

Step 2. Extra options

In the Firewall window we need to select the item Extra options:

Step 3.

In the window that appears additional settings you need to select an item Rules for incoming connections:

Step 4: Create a Rule

Now you need to create a rule. To do this, select the menu item Action – Create a rule:

Step 5. Rule Type

In the creation wizard window, you first need to select the type of rule For the program and press the button Further:

Step 6. Program

IN this step you need to select the program for which you want to apply the rule. To do this you need to check the box Program path and press the button Review. In the program overview window, select the program:

Step 7: Block the connection

Now you need to check the box next to Block connection and press the button Further:

Step 8. Profiles

In this step, you need to select the profiles for which the rule will be applied. In the example, all the boxes are checked. Select profiles and click Further:

Step 9: Rule Name

This is the easiest step. Here you need specify the rule name and press the button Ready:

That's all. Now our rule can be seen in the window Rules for incoming connections. There will also be a prohibition sign (red circle) next to its name.

Step 10. Allow the connection

If you need to allow the program to connect, then select a rule from the list and click on it right click mice. In the menu that appears, select Properties.

In the properties window, check the box next to Allow connection, press the button Apply, and then OK:

Just as parents first teach their child to speak and then to remain silent, so computer users first look for opportunities free access to the Internet, and subsequently - the ability to close access to it. What are the reasons that force you to give up the Internet, and what simple methods we will try to consider this in this article.

The desire to “cut off the oxygen” to your computer may arise if you do not want to pay for traffic that will be consumed in your absence, or you are concerned about uncontrolled access to the network for your children, relatives, or work colleagues. Also, it is quite understandable to fear information leakage when working with specialized programs and confidential information. Alternatively, it may be necessary to block access to the network for gaming or other programs, without restricting access to the network individually, but completely blocking access to the Internet.

We dare to offer you a few more or less radical ways Internet blocking on a computer under Windows control 7:

• Shutdown network adapter in system
• Setting the wrong proxy in system settings
• Block outgoing connections using the built-in firewall
• Blocking connections using third-party firewalls
• Installation parental controls V specialized programs and antiviruses
• Contact specialists to set up Internet access blocking

1. Disabling the network adapter in the system

This radical method completely deprives the computer of communication with the outside world, be it the Internet or the local network. You need to open “Device Manager” (following the path Control Panel / System and Security / System),

where, having found yours network card, right-click on its name and select “Disable”:

The network card will be disabled for all computer accounts and it will only be possible for a user with administrator rights to return it to work by going all the way from the beginning and selecting “Enable”.

2. Setting the wrong proxy in system settings

This method forces programs to use false proxy server settings (for example, you can specify the address of your own computer, 127.0.0.1) and is good because you can set it for each account separately. However, one downside is that it can be easily disabled if the user knows where to do it - there are no user rights restrictions for this setting.

Launching Internet Explorer, and opening “Internet Options” on the “Connections” tab, click the “Network Settings” button:

In the window that opens, set the proxy server address to 127.0.0.1 - and if a proxy server is not installed on your computer, programs that use the system proxy will be severely deceived.

Unfortunately, not every program uses the system proxy address, so this method may not be applicable in every case.

3. Block outgoing connections using the built-in firewall

Using this method, you can block outgoing connections via TCP protocol, blocking access to the Internet to programs trying to gain access there.
Open your firewall settings (Control Panel / System and Security / Windows Firewall) and select “Advanced settings”:

Next, you need to create a new rule in “Rules for outgoing connections”:

The rule must be created “for the port”:

Specify that the rule for all dedicated ports is:

Select “block connection”:

Enter a name for the rule that you understand:

After creating the rule, you can verify that the Internet connection is blocked. Now, at any time, you can either turn it off or turn it on again.

Please note that changing firewall settings is only available to users with administrative privileges.

Often, users do not search the Internet for information on how to block an application from accessing the Internet. Usually everyone wants programs downloaded to their computer to have normal access to the network and access the Internet without problems. Still, there are times when some application needs to block access to the Internet. If you found this instruction, then you already know why you need to turn off the Internet individual programs. Below you will find a description of how to do this.

Warning Note: If you do not have an Administrator password or an account with Administrator rights, you will not be able to complete all of the steps in this guide.

Another warning: These instructions provide changes to the settings of the Windows Firewall, also known as the firewall. We recommend that you do only what is described in the article and refrain from mindlessly changing various firewall settings if you do not understand what you are doing. Such practices can cause damage operating system and its incorrect operation.

How to prevent a program from accessing the Internet in Windows 10

The firewall built into the system is responsible for issuing Internet access permissions for all applications on your computer. This is where you need to create a rule to block access. This is done as follows:

1. Click Win+R and in the window that appears Execute enter control. This command launches the classic Control Panel, which Microsoft in every subsequent Windows update trying to hide it deeper.
2. Go to the tab system and safety.
   
   
3. Then open a subgroup Firewall Windows.
   
   
4. On the left side of the screen, click Extra options. A little tip: instead of wandering around the Control Panel, you can go straight to the Windows Firewall management interface. To do this you need to click Win+R and enter the command wf.msc.
   
5. A window will appear Firewall Windowsin mode increased security . On the left side, click on Rules for outgoing connection.
   
6. On the right side of the screen, click Create a rule.
7. The firewall will open the Create Outbound Rule Wizard. The first stage is choosing the type of rule. Since you need to block the application’s access to the Internet, select the first option - For the program. Click Further.
   
8. The next step is to specify the path to the executable . exe- application file. Click Review and in Explorer, find your application.
   
9. Please note that despite selecting an application on the disk C, the system registered the path using variables in the form % SystemDrive% . You need to change this to the normal path, otherwise the rule may not work. In previous Windows versions There were no problems with this, but now there are, sad but true. Instead of % SystemDrive%\Xiaomi\XiaomiFlash\XiaomiFlash.exe the path should look like C:\Xiaomi\XiaomiFlash\XiaomiFlash.exe. In exactly the same way, you need to correct the path if you use % USERPROFILE% . Of course, instead of folders with program files for firmware Chinese phones you will have the path to the application for which you are going to disable Internet access. The main thing is to change the variables at the beginning of the path.
10. Next, you tell the firewall what to do with the connection. Select the last option - Block connection. Click Further.
    
11. On the next screen, specify the profiles to which the created rule will be applied. Leave all three checked so that the application does not access the Internet if your computer is connected to another network. Alternatively, you can make sure that the application does not go online only in public networks. To do this, leave a mark only next to Public. By analogy, you can make other combinations. To prevent the application from accessing the Internet in home network, just leave Private.
    
    
12. The last task is to provide a name and description for your rule. Name it so that it is easy to find and delete or change later.
    
13. Click Ready.

After this, the rule will be saved and will be displayed at the top of the list of rules for outgoing connections. All saved rules take effect immediately.

How to allow an application blocked by a firewall to access the Internet

You can also allow the connection by double-clicking the left mouse button on the rule and in the section Action tabs Are common choose Allow connection. Then click OK. In the same way, you can edit the parameters of the created rule.

Another option is to remove the rule completely. Just click Delete in the right side of the firewall window, after selecting your rule to block Internet access.

The bulk software V automatic mode sends certain data to the Internet. In the case when the user is interested in prohibiting this activity, he primarily uses the capabilities of a firewall or antivirus. At the same time, no attention is paid to the possibility of such Windows tool, like Firewall.

At the same time, prohibit using of this instrument- This is the simplest process. Its implementation is determined by a simple set of specific actions.

Windows 7: Deny Internet access

1. Launch Firewall, located in the “System and Security” folder.

2. Select the “Advanced options” menu in the left column.

3. On the left, check the item “Rules for outcome. connections”, and in the column on the right, activate the first item “Create a rule” and check “For the program”.

4. Then we indicate the path to the program to which we are going to deny access; to do this, use the “Browse” button to find not just the folder with the program, but a file with its name and extension.exe.

5. After this, check the “Block connection” option and “Next” again.

6. In the window that opens, do not change anything and move on to the next window to assign a name to the rule. The name line is required, but the description can be omitted.

Use the operating system firewall (firewall).

If you use a third-party firewall or antivirus with a built-in firewall, you can configure it there. However, if there is no such software, and you do not want to install and bother, then you can use the 3rd option. Believe me, it is no worse than the first two options, on the contrary, it is clear and effective. So let's begin!

First of all, you need to open windows firewall. To do this, go to Start – Control Panel – Windows Firewall.

A window will open where you will need to enter Advanced Settings.

Here we need to create a rule for specific program, which needs to be blocked from accessing the Internet. To do this, go to Outgoing connection rules and select Create rule on the right side.

Here you need to select Block connection and click Next again

Here, let all the checkboxes be checked, click Next again.

We are almost there, all that remains is to enter the name of this rule and its description. The name must be written (name it the same as the program itself). The description can be written according to your wishes, this is done for convenience. Now click Finish and our rule will appear in the Firewall list.

After such manipulations, Opera will no longer be able to transmit any information, but it will be able to receive. To deny the program access to incoming traffic, you must repeat the above steps only for the category rules for incoming connections. I think there is nothing complicated about this. To remove our established ban it is necessary to delete this rule in both sections. Thank you for your attention and see you again!
