The best firewall software will protect from viruses, malware, and adware and provide powerful security. Windows Defender is the best firewall for protecting against hackers and viruses in Windows 10. This software is different from Mac OS and Android.
A personal firewall is beneficial for home computing and office users. It is always best to use the free firewall protection to cause fewer issues. The names of Windows Firewall vary from Windows 7 to 10.
In my experience of 20 years, I have always used the built-in firewall provided in Windows 10 or 7 or XP. This free firewall allows you to easily enable and disable security features in 2019.
Every Tuesday, Microsoft releases security patches for Windows 7, 8, 8.1, etc. to contain the security flaws that hackers exploited.
In this Windows 10 firewall review, you will see the features and functions.

4. When there is incoming traffic, it matches with the IPs of outgoing packets to ensure that it is the right data.
5. Exceptions can be made to allow unexpected packets to pass through the firewall.

Why You Need a Free Firewall for Windows 10
Once you start using the 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. sneaking 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 remarkable 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 the firewall in Windows
In India, some ISPs disable the firewall to speed up the Internet.
As the firewall processes the incoming and outgoing traffic, there is a small delay in the opening of web pages and operation of any apps that use the Internet.
This is my observation.
But if you disable the firewall, you are removing the security guard that 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, 8, 8.1, or 10 is the built-in one that Microsoft itself developed. 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 be 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.
Conclusion
In 2019, there is no necessity for installing a third-party firewall. Generally, the antivirus product owners, 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 provides.
If you think a program that’s allowed by default is causing a security vulnerability, you can manually block it.
Sometimes apps like iTunes require you to give permission for installation and passage.
If a new program is installed, the Windows 10 firewall sometimes shows a pop-up asking whether it should be allowed access in a private or public network.
Occasionally the antivirus, apart from 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 antivirus in combination with the built-in firewall.
This combination also helps maintain the optimum level of protection while keeping speed. Finally, you should avoid websites that are prone to causing virus issues on your computer.
A careful investigation of sites you visit and Microsoft-supported programs will keep your computer in optimized condition.
Otherwise, you will need to format your OS, which takes time and results in the loss of your valuable documents.
I’m really happy that Windows 10 Firewall is free. It stops many of the viruses and phishing sites. Thanks for the Info.
