The word "firewall" is borrowed from German language and means "a wall that prevents the spread of fire." Another name for a firewall is a firewall or firewall.
Based on these names, you can understand that a firewall serves to protect a computer from unauthorized actions of hackers and malicious software. A firewall can also prevent information leakage from your computer, so it is not recommended to ignore it.
As a rule, most users are satisfied with the built-in firewall, as it protects the computer quite reliably. Of course, you can install a more powerful firewall, but in this case you need to remember that such programs “eat up” a lot random access memory and need to be configured correctly.
How to enable the firewall?
So, you have the built-in Windows 7 firewall installed on your computer. How to enable it? This is actually very easy to do.
Open the Start menu and go to Control Panel. To make it more convenient, in the right top corner Select Small Icons view. Now find the section " Windows Firewall" and open it.
In the left menu you will see the corresponding item, by clicking on which you can enable or There are two options:
- You can run a firewall for home network, but they usually don't do this, even if you don't have any other antivirus protection.
- Enable a firewall for public networks.
Remember: if you use an antivirus, such as Avast or Kaspersky, then you need to disable the built-in firewall so that it does not conflict with the one you installed. Read on to learn how to turn off the Windows 7 firewall.
Disabling the firewall
You know how to start the firewall, so disabling it should not be difficult, since you will need to perform the same steps, but in reverse order.
Go to the Start menu, open Control Panel again, select the Firewall section. Now click on “Turn firewall on or off” and check the appropriate option. In this case, you can disable, for example, only the firewall for the public network. But remember that deactivating the firewall can lead to serious problems, because the computer will become vulnerable to attacks from viruses and intruders.
Now you know how to turn off the Windows 7 firewall, but you also need to turn it off in Services.
Disabling the firewall in the Services menu
Using the above method, you only disable the program itself, but the firewall service continues to work, so it must also be deactivated.
Open Control Panel and then Administrative Tools. Now go to the Services section. Here, find the “Windows Firewall” item, in the window that opens, set the startup type to “Disabled” mode, and then click the “Stop” button.
You can make it simpler. The Start menu has a search bar. Write the word “services” in it and follow all the steps described above.
To make sure that the firewall service is indeed deactivated, open the System Configuration section and see if the firewall service is there. If it is present in the list, then uncheck the box next to it.
Windows 7 Firewall Exceptions
Sometimes a firewall blocks programs that you need. To prevent this from happening, you need to add them to the “Exceptions”.
Go to the “Windows Firewall” section and enable it by clicking on the appropriate item in the left menu. Opposite those for which you want to make an exception, check the box.
Now the firewall will ignore the marked programs, and you will be able to use them without any problems. But remember that if you downloaded them from dubious resources, then it is not recommended to use this function. You know how to enable the Windows 7 firewall, so activate it.
If you need to open a port
There are situations (for example, with games) when you need the Windows 7 Firewall to do this.
Go to Control Panel and open the firewall section. Select " Extra options" You should see a separate window where you will need to select “Rules for incoming connections”. In the right menu, click “Create Rule”. Select the “For port” option and specify the protocol suitable for your case. Enter the port number in the appropriate field. If there are several of them, they are written with a hyphen.
In order to check whether the port is open or not, you can go to the site where you can do this. There are quite a lot of such services on the Internet. Google or Yandex will help you find them.
The firewall does not start. Options for solving the problem
If the Windows 7 firewall does not turn on, there are several ways to solve this problem. For example, you can paste a specific file into Notepad and then save the document, naming it Repair.bat. In this case, the file type must be specified as “All files”. After that, run this document as an administrator. You can do this by right-clicking on it and selecting the appropriate item.
Alternatively, go to the Microsoft website. There at the bottom, select the language that suits you and go to the “Support” section. Use the search box on the site where you can enter the question you are interested in.
Here you will find a file that needs to be pasted into Notepad, and other options for solving the problem with the firewall. Sometimes, for the firewall to start, you just need to scan the system with an antivirus program and delete malicious files.
So, you already know how to open the Windows 7 firewall. Do not forget to follow all the recommendations for using the firewall:
- If your computer is quite old, then use the built-in firewall, as more powerful firewalls consume a lot of system resources.
- When you have an antivirus installed that has its own firewall, the built-in one must be disabled so that they do not conflict with each other.
- Do not add programs that you downloaded from dubious sites to exceptions, as this may harm the system.
- For a home network, the firewall does not need to be enabled, but for public networks, its activation is required, since information may leak from your computer, or a virus may enter the system.
- Quite a lot of information on troubleshooting firewall problems can be found on its “native” Microsoft website.
Conclusion
Knowing how to turn on the Windows 7 firewall, you can minimize the risk of unpleasant situations. Of course, it is advisable to install a more reliable antivirus on your computer, but even a built-in firewall can protect you from losing important data or from hacker attacks.
Remember: do not completely disable the firewall if one program does not work with it. It's better to figure it out, maybe it contains a virus. Or try to figure out what the problem is. But in any case, deactivating the firewall is highly undesirable.
