Top Rated Best Free AntiVirus for Windows 10

1) Avast Free Antivirus for Windows 10:

Avast is one of the most preferred full-featured internet security solutions. It’s not difficult to see why this is one of the top choices for Windows 10 or 8.1. It’s incredibly easy to install, and simple UI and lightning-fast virus scans make it a perfect choice for everyone.

The best part is that it uses minimal system resources, meaning it won’t bog down the user’s PC, a major reason why people with old PCs depend on Avast for their virus protection needs. It includes an updated menu from where the latest updates can easily be downloaded and a built-in firewall to improve protection from cyber-attacks further.

Per the company’s records, they are protecting over 200 million PCs, Macs, and Androids. The newly streamlined user interface of Avast includes several options to detect and clean up malware. In addition to the common security tools, such as Anti-malware Protection, Anti-spam, Software Updater, and SafeZone, Avast includes some interesting features like;

2) Avira Free Antivirus:

Next up on the list is Avira Antivirus. Avira is the top-rated and popular security solution to protect your PC from viruses, adware, spyware or malware. The decent scanning speed, excellent usability score, and ability to deal with the greatest threats are some of the highlighted features of Avira Antivirus.

Moreover, the antivirus uses only limited resources, making it easy to load and use other applications without lag. Before installing any new software ensures that the software is compatible with your PC and helps avoid crashes.

Like Avast, Avira includes built-in firewall protection but also has a bonus. It has a child monitoring service that allows you to monitor what your children do on social networking sites, automatically flagging friends who appear to be adults and identifying possible profanity, drug or alcohol references or depression-warning signs. There is, however, one downside to Avira, if you have a PC with less than stellar specs, it will slow down during scanning.

3) AVG AntiVirus Free

AVG antivirus is a heavy hitter against malware, but that is mostly true for the paid version. The AVG antivirus has incorporated many useful features, which can make you safe while surfing the internet. The smart and simple user interface makes things much easy for the users to carry out the operations with a few clicks. The advanced settings and good localization have taken it far ahead of its rivals.

The free version is no slouch either; it’s enough for most of our malware removal needs thanks to its superb virus detection engine. AVG’s UI is rather clunky; some users might struggle to navigate it. It is best suitable for people who have a better understanding of how Antivirus programs work.

4) Bitdefender Antivirus Free Edition

The latest Bitdefender Free Edition is a complete suite in itself. It offers basic protection from the latest viruses and security from malware and phishing scripts; Bitdefender provides real-time protection, antiphishing, autopilot and anti-malware protection.

You can install free Bitdefender software on any number of devices independent of platform type. You can download antivirus on Windows, Android and Mac devices for free. Once you download and run the installer, it will scan the system for any active malware that could hinder the installation process. The Bitdefender user interface is simply offering you many options to choose from on a single screen.


The best feature of Bitdefender is its auto-pilot mode which is always ‘On’ by default. The autopilot will silently secure your PC, laptop, smartphone or tablet from all malware and phishing attacks so that you can do your financial transactions or save your personal data without any threat of being hacked.

Among all the free anti-malware products, Bitdefender is a strong contender to be on the top, considering its all-around performance.

Centralized interface to manage all the devices
Protects devices silently
Simple User Interface
Quick and Easy Installation
Outstanding Lab results

Some threats can be eliminated only in rescue mode.

5) Comodo Antivirus

The Comodo version is a “feature-filled antivirus software” that is absolutely free. Comodo offers a nice-looking interface. It offers a number of themes like classic, modern, Lycia and much more. The main screen consists of a large block showing the current protection status.

If everything is protected, the block will appear in green color and the case of some cyber-attack, or if some of the components are disabled, the rectangular block will become red in color. On the right side of the screen are other components that include manual scan, update, Run Virtual and unblock applications (from the sandbox).

Comodo PC Protection

The installation of Comodo is tricky. You have to be careful and read the installation screens carefully before clicking yes or next since any laxity during installation will install Yahoo as a home page in all browsers.

Similarly, after the installation is complete, a Geekbuddy service will pop up asking for remote scanning and remedy of malware. If you accept the offer, thus Geekbuddy will later ask you to pay for remote services. So I don’t recommend paying for any of their services since the Comodo 10 free antivirus software is perfect for overall protection from any cyber-attacks.

The best part of this free antivirus is the sandbox virtualization feature. It can easily create a virtual desktop and all your applications and browser run in a sandbox. Any changes done to files by malware or phishing attacks are temporary and can be reset by clearing the sandbox.

Premium features like HIPS and Sandbox in the free edition
Option to create a rescue disk
Safe Comodo Dragon (Chromium-based) browser
Good-looking user interface

 Not convincing lab test reports

The interface is clean and simple to use. Apart from a local interface, Sophos has a user-friendly management console to control the settings and analyze the reports of multiple systems.

The interface is beautiful, with natural landscaping in the background. Panda is a great companion for your device, protecting it silently from exponentially increasing malware, phishing and virus attacks.

Installation is easy and lets you customize the settings during installation, but you can also alter these settings later after installation. Panda has developed an improved safe web component that provides a robust shield against online phishing and fraudulent sites that attempt to steal vital information related to financial transactions or email accounts.

Panda Free Antivirus

Panda free edition offers many bonus features, including USB protection which scans USB drives automatically when inserted, Process Monitor to view a comprehensive list of all the processes executed on the device, and Rescue Kit to weed out malicious programs that hinder the booting of your system.

Quick and Lightweight
Premium features like USB vaccination and rescue disk included in the free edition
Overwhelming independent lab tests reports

Pop-ups to register for a paid version

Overall a good and lightweight antivirus, and if you have access to the internet all the time, it is a recommended option in the year 2022.

We highly recommend reviewing and installing one of the above free AntiVirus software on your computer. The built-in Windows Defender could be very basic antivirus protection that can’t fight against all the latest viruses and threats attacks.

Alternatives for Best Free AntiVirus for Windows 10: Paid Software

Each of the above companies has its paid version with advanced features and network protection. They work better as firewall protection and block network/online threats while you surf online. If you are looking for alternatives to free antivirus software, the next option is to buy the paid version of your favourite PC protection software.

Other than the above three antivirus software such as Avast, Avira and AVG paid versions; you can consider these below paid antivirus software. Most of them provide 30 days trial period with full options. You can download them for free and try them on your PC. Assess the performance of your Windows 10 computer during the trial period and then decide on the purchase.

  • Kaspersky: A famous and powerful antivirus software for your PC.  They are good at researching and fighting against new viruses and threats.

Final Thoughts

Antivirus programs are awesome at what they are designed, which is removing malware, and with them being available for free, it would be foolish not to install one.

Whether you want a program with a low footprint, a heavy hitter that can detect the most well-hidden malware, or one that can do both, my list has you covered. Go ahead and select one of the best free antivirus software for Windows 10/11 and download them for free.

Do not miss trying the trial versions of paid software if you are looking for more protection at a cost.

  1. Thank you for your tips on free virus protection. My Webroot has expired. My computer is now telling me I have 3 virus within a month of no protection. Your page might just be a life saver for both my pc and I. Thanks a bunch. Heather from New Orleans

  2. you need to add Panda to your list it is a great free antivirus some might think it isn’t very user friendly , but for me it’s been a download and forget type of thing. very hassle free.

  3. I no longer think AVG is a contender with some of the antivirus programs that are available now.

    I do agree avast is on top for now, its the program I use and I havent found one good enough to replace it quite yet.

  4. Using most recent Avira Free anti-virus on my laptop. Every other time or so that I start my laptop, Avira needs to install updates before my computer is “Protected”. It’s kind of a pain. I understand that programs require updates, but I never noticed this kind of update frequency with other anti-virus programs. Looking for another anti-virus program.

  5. I have used the free edition of AVAST for years but I got a new laptop with Windows 10 and have had nothing but problems AVG with AVAST ever sense, So a friend said try AVG but I used them a long time ago so I was hoping for some advice on what others who use Avira think of it. Friends keep telling me how great it is for a free program. Really need some honest input. I would like to try the free version and then maybe upgrade to a paid version as I would like one that has PC clean up options. Thanks for any help you can give. I am using Norton right now that someone bought for the 5 PC users but I do not like Norton. wants to do things to my computer that I am not comfortable with. Any advice is appreciated . Thanks, Carol

  6. I personally would recommend Bullguard Internet Security, Computaplace are currently doing it for 20 pounds, its based on bit defender. I have been using it for a while now and do an awful lot of web browsing and torrent downloads and so far… so good
