6 Great Free PC Security Tools For Windows

Hey guys, in this post I’m going to explain how to secure your personal computer with minimalistic efforts. All you need is a working PC and an internet connection.

System Requirements are Simple :

  • Minimum of 1GB RAM (2 GB Advised)
  • Operating System – Windows 7 or Above.
  • Processor – Pentium and above.

What we’re basically talking about here is on how to make your PC even more secure. So, here’s a list of software that you can use to make your PC safe from malware, viruses, worms, network attacks, phishing, key-loggers, etc.


What it basically does is it encrypts your keystrokes, thereby protecting you from key-loggers.

It supports nearly all the browsers available in the market. While the free version supports al the browsers, the Premium version can do even more – ” Premium protects your login credentials in Windows workstation, Active Directory Domain, Windows Vista’s User Account Control prompts (UAC), and all of the Windows Store (Metro) Apps.

Premium protects every of your keystrokes in 32- and 64-bit Windows programs, East Asian languages, and in apps that have become essential in our lives: Word, Excel, PowerPoint, Access, Quicken, TurboTax, Quickbooks, Dropbox . . .”

For most normal 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 ~1.5 MB, it just takes a minute to install. Once installed, you can forget about it. It’ll start doing its job – encrypting your keystrokes.

Its Real-time key encryption defeats keylogging.

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.”

— BBC News

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 suite. Why I’m saying this is because when your system gets compromised the attacker will be able to run scripts that can disable your antivirus service but having different components separately installed can make it hard for the attacker to compromise your system’s security setup.

If you think this basic KeyScrambler encryption is not enough then you can check out the list of other Useful Extensions for Browsers to enhance your security even more.

Comodo Free Firewall

The first and the foremost component is the Firewall.

After having a look at the list of firewalls available on the net and the reviews about it, I came to a conclusion that ‘Comodo Firewall’ is the one of the best firewall programs available out there committed to provide full-fledged security to your systems inbound and outbound connections.

The Free version is nearly as good as the Premium/Pro version of the software.

Anti-Virus Engine

Now your firewall service is secured. Now let’s go to antivirus engine. Thinking about which is the best one out there?

To be honest, all the antivirus engines (be it the free version or the premium/pro ones) do the same job – detecting viruses and getting rid of them. I would suggest you guys to go for ‘Avast Free Antivirus’.

It is light on the system resources and detects and removes most of the viruses and malware.

Malwarebytes Anti-Malware

Wait, it’s not over yet!

We need an engine to scan and remove malware and rootkits – dedicated for just that job!

In this field, no one can provide a better service than Malwarebytes Anti-Malware program. They’re like, the pioneers in this field. What more, they can also block malicious web links for you and malicious inbound/outbound connections too. It’s just more than a anti-malware – you can’t bargain for more!

Malwarebytes Anti-Rootkit

Also they’ve got their own dedicated Anti-Rootkit software too. You can use it to remove the rootkits and repair the damage caused by them.

But be warned, it’s still in the Beta stage. If you get your system crashed because of it, you can’t complain them. Proceed at your own risk!


Last but not the least – a software to wipe away unwanted data (Internet Cache, Internet History, Cookies, Sessions, Recently Typed URLs, Recent Documents, Thumbnail Cache, Memory Dumps, Temporary Files, etc ., just to name a few. It has also got an in-built registry-cleaner which is simple to use and hassle-free. What more, it has also got a disk analyser, duplicate files finder, drive wiper and options to disable start-up programs. It’s intelligent cookie scan also offers to keep useful cookis such as cookies from you e-mail service provider so that you needn’t keep logging in again and again. It makes your job simple.

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 found this information useful in securing your personal computer. 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 🙂
