How to block program access to the Internet correctly?

In life, there are a variety of situations in which we need knowledge of a personal computer. One of these things is the question of how to block the program’s access to the Internet. If you suspect any program in viral activity and think that it has been infected with some trojan, then the first thing you should do is to limit its work. Removing such programs is dangerous because the virus can spread to other applications. Therefore, we will figure out how to block the program’s access to the Internet so that it does not merge information about you to the attacker.

Windows

Let's start with the most popular operating system to date. How to block the program access to the Internet? Windows 8 uses a well-known, even from the first operating systems, firewall. In fact, this method involves extreme measures to ensure the security of a personal computer. Remember that if you close the Internet access to any application using this method, you can open it only as well. The main condition for this method will be the use of a computer administrator account, so if you try to do this trick on a working computer, then most likely you will not succeed. It is also worth mentioning that the recommendations written below on how to block the program’s access to the Internet also work for earlier versions of operating systems. In this regard, Microsoft has a conservative view, leaving the interface the same and changing only the software component.

Quick way

So, how to block the program access to the Internet through the firewall? There are two similar methods that you can use to configure your firewall. But at the same time, the beginning will be the same. First thing you need to run it. To do this, click the "Start" - "Control Panel" - "System and Security" - "Windows Firewall".

Now we are ready to block the program. First, make sure your firewall is turned on. However, you can not doubt it if you are constantly getting pop-up windows that require access permission when starting up various applications.

1. In the open firewall window, in the menu on the left, find the item "Allow program or component to be launched through the Windows firewall".
2. As the name implies, if you have problems not only with blocking, but also with lack of access, then here you can also add the program to the exceptions.
3. To block the program, just remove all the checkmarks in the row with its name.

Digging deeper

If you are a system administrator or a caring parent who decides to punish a child by blocking his favorite toy, and your wards are at least a little computer savvy, then you can use another tip on how to block the program’s Internet access. Windows 7, and any other operating system of this family, will allow you to configure a special rule in the firewall.

To do this, first repeat all the points indicated in the previous paragraph. After that, you need to do the following:

1. In the main menu of the firewall, select "Advanced Settings".
2. We need to configure "Rules for outgoing connections."
3. Having selected the corresponding tab on the left, on the right click "Create Rule".
4. Type of rule, of course, "For the program."
5. Next, specify the path to the executable file of the application. It will have the extension .exe. In rare cases, it can be .bat or any other extension of the running program.
6. In the "Action" tab, select "Block connection."
7. We apply the rule for all computer profiles.
8. And finally, enter a name to be able to find this rule among others.

That's all. We blocked the program we need. Now, if you want to return everything back, you just need to find the created rule in the list and select "Disable rule" in the properties.

Antivirus

In addition to the firewall, there are other ways to block the program’s access to the Internet. For example, you can use antivirus programs. Consider this process using the example of Kaspersky. You will need Kaspersky Internet Security of any version.

1. After installing and updating this anti-virus program, we open the control center.
2. Select "Protection Center" and in the upper right corner click "Settings".
3. We select the sub-item "Firewall", turn it on and again enter the setting.
4. In the window that opens, in the "program rules" tab, we find the application of interest to us. Click "Edit."
5. Select "Network Rules" - "Add."
6. In the new "Network Rule" window, we configure. The action is "Block". Title - Web-browsing "
7. Now you can safely press "OK" in all windows.

This method, like blocking Internet access in Kaspersky, is quite universal, but any person who is a little computer savvy will quickly find and remove access restrictions.

Firewall

Sometimes users are interested in the question of how to block the program access to the Internet “Firewall”. This is actually another name for the standard Windows firewall. Of course, you can download a third-party firewall application, but no one will guarantee that the application you receive will be 100% safe in itself. Attackers often create or infect programs designed to protect users' computers, and since before installing any antivirus you need to remove or disable the old one, virus infection occurs very quickly. In general, the choice of "Firewall" is yours.

conclusions

Having learned how to block access to applications on the Internet, do not rush to indulge in it. It is imperative to save your data or just make save points to roll back the system. Remember that if you are not well versed in computers, then any of your actions can lead to irreparable consequences, after which there will be nothing left but to contact the professionals.
