How to Build Your Own PC and Internet Security Suite For Free

Build Computer and Internet Security Suite for Free

This tutorial will teach you step by step how to build your own PC and internet security suite for free using free antivirus software, firewall, second opinion malware scanners, and ransomware protection.

But first:


Malware short for "malicious software" is software that is specifically designed to damage or disrupt a system, steal information (spy on you), or destroy data.

Malware is a broad term used to describe many different types of malicious programs such as computer viruses, spyware, worms, trojan horses, adware, rootkits, and ransomware.

Malware threats grow so fast that even the best antivirus programs take too long to catch up with malware.

Therefore, the best protection is yourself and you need to pay attention with everything you do on the internet!

You can build or buy the best computer and internet security suite, but there's always a change your PC gets infected if you don't pay attention.

And now:

How to Make Your Own Computer and Internet Security Suite For Free

Build PC and Internet Security Suite for Free

Step 1: Antivirus Software

First we will start with the core of the Internet security suite – and that's the antivirus protection.

Two good free antivirus programs are Bitdefender Free ★ and Kaspersky Free.

Bitdefender and Kaspersky are always in the top of the Antivirus tests and their free versions use the same malware protection as their paid versions.

I like the free version of Bitdefender, because it's good, simple, light, doesn't show ads, and doesn't have any bloatware.

Step 2: Firewall

Windows has already a good firewall built-in, but if you want a firewall with more settings, then you can also use a third-party firewall.

Here are two free third-party firewalls:

I'm using the Windows firewall, because it's good enough.

Step 3: Second Opinion Malware Scanners and Removal Tools

Even if you have a good antivirus program installed on your PC, there's always a change that some malware will not get detected by it.

That's why it's always a good idea to have second opinion malware scanners for scanning and removing malware (computer viruses, spyware, adware, rootkits, trojan horse, worms, etc..).

Here are a few good free second opinion malware scanners:

I have the free versions of Malwarebytes and Zemana installed on my PC and perform regular scans with them (e.g. once a week).


When I think my PC is infected with malware, then I also scan my PC with Kaspersky Virus Removal Tool and ESET Online Scanner.

And if any of these tools detected malware, then I will restore my 100% clean system image backup.

Step 4: Ransomware Protection

Ransomware has seen a significant increase in the last few years, so that's why it's a good idea to have some kind of ransomware protection.

You can run ransomware protection alongside your antivirus software.

Here are three good free antiransomware tools:

Pick one of these tools.

Note: One of the best protection against ransomware is to pay attention with everything you do online and create regular backups of your important files.
