“How to block internet access to specific program” was the subject of the email that I got last night from one of my readers. I decide to write a column about this.
Due to various reasons, we want to block internet access to our computer or sometimes we want to block internet access to program level. Another two types of blocking internet access are user level blocking and website level internet access blocking.
Reasons behind blocking internet access are very simple. In case of your home PC, your child might install a malicious program that can harm your computer (if he has full internet access). Sometimes, they want to access adult websites, and that is not desirable to you. Some installed program on your computer might cost your internet bandwidth in the background and at the end of the month it ends up with a huge internet bill. So, you definitely want to block internet access to programs those consume internet bandwidth.

Method 6 – Windows Firewall can Block Internet Access of a Program: As we all know, Windows firewall provides packet filtering and fire-walling.

Thus, you can enable or disable any internet access to a specific Windows program.
Method 7 – Use Parental Control Software to Block Internet Access to Programs (Third-party software): As I have mentioned earlier in this topic about blocking internet access to programs, all the methods were the manual way to disable internet access. However, there is an automatic solution too. Some third-party software might play the trick for you. Those are mainly firewall based parental control software that enables or disables internet access to your device or to any specific program. Internet Lock is the best in my directory that can do all the necessary things for you, and you just need to install the application. Internet Lock has the below-mentioned feature, which helps control internet connections and internet access to programs.
- Block internet access.
- Make internet access password protected.
- You can schedule the internet access for any installed programs.
- It can create a blacklist to block websites.
- Internet Lock can prevent any user from accessing internet service. Same thing is applicable to the Groups also.
How to password protect internet access using Internet Lock? Open Internet Lock and navigate to ‘Rules’ tab. Click ‘Add’ button to add a new rule. Select “Create a new rule manually”. Give the rule a name and choose a password. Then choose what you want to protect. You can block internet access to a program, ports, IP/Domains, Users, etc. by choosing any of them.
Method 8 – Block Any Windows Application from Accessing the Internet Using ‘OneClickFirewall’: OneClickFirewall is a tiny but useful Windows application that lets you block or allow the internet connection for a particular software or Windows application. This is a separate Windows firewall application which actually uses the Microsoft’s built-in Windows Firewall. The application is a freeware and you can install it in any Windows OS like Windows 7, Windows 8.1, Windows 10 etc.
The application does not provide any interface after installation. You just get two options at Windows right-click context menu. The options are as follows — (1) Block Internet Access (2) Restore Internet Access.
Just right-click on an executable file (.exe file), and select “Block internet access” from the context menu. That’s it. The program automatically creates a new outbound rule for the program and restrict the internet access for it. I have tested the software with Google Chrome browser and got the following message when trying to access the internet using the browser: “Your Internet Access is Blocked“.
However, you can disable the restriction any time by pressing the “Restore Internet Access” option. You can download the tool from the URL mentioned below.
Effect of Blocking Internet Access (Things to Remember):
- Disable internet access to a specific program means the program can run without any internet connection.
- No update is required for that particular program.
- Check firewall exceptions for unauthorized windows programs.
- Every method which I have mentioned above is reversible.
You can configure internet access filtering using most of the popular internet security software. In case, you are using such application on your computer, then you should be conscious enough before using the application and should know how to configure your PC to block internet connection properly.
