Why You Need a Free Firewall for Windows 10

Once you start using Internet, software programs and apps installed on your PC will try to make incoming and outgoing connections for different reasons.

You will not know what information they are getting in and out. Even if you are using torrent clients, there is a risk of malware, trojans, viruses etc to sneak through.

To protect from all these evils, the “firewall” is introduced in the late 1990s.

It acts like a barrier between the outside network and your computer. If it suspects that any worms or viruses are getting into your system, it blocks that kind of traffic.

Another interesting feature developed by Microsoft is that you can block an app or program to communicate with the outside world or allow it.

The simplicity of this feature is that once you install any firewall it automatically takes care of the security of your computer.

Is it good to disable Firewall in Windows

Personally in India, some of ISP providers disable the firewall to make Internet fast enough.

As firewall processes the incoming and outgoing traffic, there is a small delay in opening of web pages and operation of any apps which use Internet.

This is my observation.

But if you disable the firewall, you are removing the security guard which prevents the demons from entering into your computer.

So when you decide to use third-party firewall software, you should choose wisely based on  user experience between speed and security.

In my view the best firewall for Windows 7 or 8 or 8.1 or 10 is the in-built one that is developed by Microsoft itself. The main reason is that no one knows better than the mother.

If you are using a third-party firewall, they don’t know the full functionality code of Windows. So there may hiccups which can hinder the performance of your computer regarding speed and security.

Some of them are difficult to uninstall. Some leave registry entries (even after cleaning) and limit the functionality of programs and apps.


In 2019, there is no necessity of installing a third-party firewall. Generally the anti-virus product owners in order to boost up their sales boast about a free firewall along with their standalone product.

But the built-in Windows firewall takes care of many of the functionalities in protecting your PC.

One can configure the performance of the firewall and the level of protection it can do.

You can manually block a program that’s allowed by default, if you think its causing security vulnerability.

Sometimes apps like iTunes requires your permission to allow installation and passage.

If a new program is installed, Windows 10 firewall sometimes shows a pop-up whether it should be allowed access in a private or public network.

Sometimes the anti-virus other than Windows Defender if installed may not play well with third-party firewalls.

The best protection for your computer is to use Windows Defender as an anti-virus in combination with in-built firewall.

This also helps keep the optimum level of protection and maintain speed also. Finally you should avoid websites which are prone to cause virus issues in your computer.

A careful investigation of sites you visit and Microsoft supported programs will keep your computer in optimized condition.

Otherwise, you need to format your OS, which is a waste of time and also lose your valuable documents.
