Why PC security matters
Nowadays, everything is designed, created, processed, stored, and transferred online. Even money (cryptocurrencies) can be mined by utilizing the power of your CPU and other system resources. So, keeping your PC secure is more important than ever to keep you safe from digital threats. Especially from growing threats like NotPetya, WannaCry, and other ransomware attacks.
Personal computer security is very important because it is the first step of defense against unauthorized access to your computer. Once your computer is hacked, it can be used for illegal purposes like becoming part of large botnets to carry out large-scale distributed denial-of-service (DDoS) attacks.
List of best free PC security software
In this article, I’m going to explain how you can secure your personal computer without putting in much effort by just relying on some of the best free PC security software. All you need is a working computer and a stable internet connection to follow this article.
Now, here are some basic system requirements before you can start downloading and installing the free yet powerful tools I’ve suggested below –
- Minimum of 4GB RAM
- Operating System – Windows 10 or Above.
- Processor – Pentium or above.
What we’re basically trying to do here is to make your computer even more secure so that you can shield yourself and your family from attacks originating carried out by malicious programs and resources online. Here’s a list of software programs that you can use to protect your computer against malware, viruses, worms, network attacks, phishing, key-loggers, etc.
Free Anti-Keylogging Software (KeyScrambler)
What KeyScrambler basically does is that it encrypts your keystrokes, thereby essentially protecting you from key-loggers. It supports nearly all the major browsers available on the market such as Google Chrome, Mozilla Firefox, Opera, Apple Safari, etc. While the free version itself is enough to support all browsers, the Premium version can do even more. The premium version of KeyScrambler can protect your login credentials on a Windows workstation, Active Directory Domain, Windows Vista’s User Account Control prompts (UAC), and all of the Windows Store (Metro) Apps.
Moreover, KeyScrambler premium protects every keystroke of yours when using any 32 or 64-bit Windows programs, East Asian languages, and apps that have become essential in our lives such as Microsoft Word, Excel, PowerPoint, Access, Quicken, TurboTax, Quickbooks, Dropbox, etc. For 90% of normal PC users, the free version is just fine but if you’re extra worried about your privacy, then go for the premium version.
With a setup size of less than 1.5 MB, it just takes a minute to install and activate. Once installed, you can forget about it as It’ll start doing its job of encrypting your keystrokes. Its real-time key encryption feature defeats all keylogging software. Just look at what BBC News had to say about KeyScrambler –
“KeyScrambler from QFX Software can protect users from phishing emails and malicious websites that deploy key logging software to mine your personal details.”

If you think this basic KeyScrambler encryption is not enough then you can check out the list of other useful tools to enhance your PC security even more.
Coming to the next point it would be safe to say that installing separate software components for an antivirus setup is better than installing a full-fledged antivirus or internet protection suite. The reason why I’m saying this is because, when your system gets compromised the attacker will be able to run malicious scripts that can disable your antivirus service but having different components separately installed can make it difficult for the attacker to find the different security components of your computer and compromise its security setup.
Firewall Software
The first and the foremost component for defending your computer from online threats is the firewall. Though there are many free and premium firewall software solutions available out there, I suggest you go with Comodo. I came to the conclusion that ‘Comodo Firewall’ is the best free firewall software available out there because of its commitment to providing full-fledged security to your systems inbound and outbound connections over the internet. The free version is nearly as good as the Premium/Pro version of the software.
Anti-Virus Engine
Now that you have set up a firewall to monitor the quality of incoming and outgoing traffic, let’s go to the step of choosing an antivirus engine for your computer. Thinking about which antivirus is the best one out there? To be honest, all antivirus engines (be it the free version or the premium/pro ones) perform the same job – detecting viruses and getting rid of them from your computer. I would suggest you go for Avast’s free antivirus. It is light on the system resources and detects and removes most of the viruses and malware. Moreover, it is the best antivirus for PC which comes with a free download of the full version.
Anti-Malware Program
Just by installing an anti-keylogger, a firewall, and an anti-virus engine, your computer is not secure yet. You now need a software program to scan and remove malware and rootkits from your computer. Worry not, I have already looked for the best solution out there and it is none other than Malwarebytes which is dedicated to doing just that.
No one can provide better cybersecurity and anti-malware software other than Malwarebytes. They are like the pioneers in their field. Malwarebytes is simply the best malware removal tool currently available out there. What’s more, they can also block malicious web links for you and filter malicious inbound and outbound connections too. It’s just more than an anti-malware – you can’t bargain for more!
Anti-Rootkit Software
Malwarebytes have got their own dedicated anti-rootkit software too. You can use it to remove rootkits from your computer and repair the damage caused by them. Rootkits are nothing but malicious software programs that hide in your computer with privileged access and permissions. They are usually difficult to detect because they hide under the guise of a useful program.
But be warned, it’s still in the beta stage. If you get your system crashed because of it, you can’t complain to them. Proceed at your own risk!
System Cleaner
Last but not least – here’s an application to wipe away unwanted data such as browser cache, internet history, cookies, sessions, recently typed URLs, recent documents, thumbnail cache, memory dumps, temporary files, etc from your computer. It has also got an inbuilt registry cleaner which is simple to use and hassle-free. What’s more, it has also got a disk analyzer, duplicate files finder, drive wiper, and options to disable start-up programs. Its intelligent cookie scan feature allows you to keep useful cookies such as cookies from your e-mail service provider, social networking sites, etc so that you needn’t keep logging in again and again. It makes your job simple. Oh well, I’m talking about CCleaner.

Note:
Nearly all the programs mentioned above have got both – a free and a paid version with extra features. But the free version is nearly as good as the paid one but if you’re really interested in the product and want to support the developers, you can buy the premium versions. That’s up to you to decide.
Hope you people found this information useful and helpful in securing your personal computer and hardening its overall security. Will be meeting you guys in my next post about the best extensions for Google Chrome (and other browsers based on the Chromium Project). Stay Tuned 🙂
