How can I block access to the Internet correctly?

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

Windows

Let's start with the most popular operating system at the moment. How to block the program access to the Internet? Windows 8 uses all known, even since the first operating systems, a firewall. In fact, this method implies extreme measures to ensure the safety of a personal computer. Remember that if you close the Internet access to an application using this method, you can open it only as well. The main condition for this method will be the use of the computer administrator account, so if you are trying to do this trick on a work computer, then, most likely, you will not succeed. It is also worth mentioning that the recommendations below, how to block access to the Internet, work for earlier versions of operating systems. In this respect, Microsoft follows conservative views, leaving the interface the same and changing only the software component.

Quick way

So, how to block the program access to the Internet through a firewall? There are two similar methods with which you can configure the firewall. But the beginning will be the same. First of all you need to run it. To do this, click the "Start" button - "Control Panel" - "System and Security" - "Windows Firewall".

Now we are ready to lock the program. First, make sure that your firewall is turned on at all. However, you can not doubt this, if you constantly get pop-up windows that require permission to access when launching various applications.

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

Digging deeper

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

To do this, we 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 the "Rules for outgoing connection".
3. Select the appropriate tab on the left, then click "Create rule".
4. Type of rule, of course, "For the program."
5. Next, we specify the path to the executable file of the application. It will have an .exe extension. In rare cases, this can be a .bat or any other extensions of programs being launched.
6. In the "Action" tab, select "Block connection".
7. Apply the rule for all computer profiles.
8. And, finally, we enter a name to be able to find this rule among others.

That's all. We blocked the program we needed. Now, if you want to return everything back, you will 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 access to the Internet. For example, you can use antivirus software. 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, open the control center.
2. Select "Protection Center" and in the upper right corner click "Settings".
3. Select the sub-item "Firewall", turn it on and go back into the configuration.
4. In the opened window, in the "program rules" tab, we find the application we are interested in. Click "Change".
5. Choose "Network Rules" - "Add".
6. In the new window "Network rule" we carry out the adjustment. Action - "Block". Title - Web-browsing "
7. Now you can safely press "Ok" in all windows.

This way, as in Kaspersky, to block the program access to the Internet, it is universal enough, but any person who understands computers at least a little will quickly find and remove the access restriction.

Firewall

Sometimes users are interested in the question of how to block the program access to the Internet "Firewall". In fact, this is 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% secure in itself. Attackers often create or infect programs designed to protect users' computers, and since before installing any antivirus it is necessary to remove or disable the old one, then the virus infection occurs very quickly. In general, the choice of "Firewall" is yours.

conclusions

Having learned to block access to applications on the Internet, do not rush to mess with it. Do not forget to save your data or just make a savepoint to roll back the system. Remember that if you do not know enough about computers, then any of your actions can lead to irreparable consequences, after which nothing will remain, except how to turn to professionals.
