Best Free Antivirus Software For Windows | Updated For 2021


There are a bunch of Antivirus out there but most of them you have to pay something to use it. which basically means It’s not free to use and difficult for those users who can’t afford it and still want protection on their system. So here we came to solve that problem and give you some of the best free antivirus software to protect your windows machine from getting hacked or stealing data. 

List of the Best Free Antivirus software For Windows Machine

We definitely need some sort of antivirus to protect our information but not everyone going to buy one to get protected but we can find the free one and use it even they have some limitations. So let’s check out some of the best free antivirus software to protect your windows machine.

Kaspersky Security Cloud Free

Kasperksy is a highly rated antivirus tool with a good amount to offer for free services. This Antivirus is listed as the top of the  Best Free Antivirus software For Windows machines. Also, the important part of this software is it doesn’t try to install any extra software as Avast does. But it will ask you to create a Kaspersky account during installation. Just be sure to uncheck the box about receiving marketing materials otherwise you will get a bunch of unless emails from Kaspersky every single time.

further, The free version of Kaspersky supports the various scanning options which you can expect from other paid tools, including scans of external devices, and the ability to schedule scans. Also part of the free package is Kaspersky’s password manager and Secure Connection VPN with a 300MB data usage limit every single day.

What you don’t get are the privacy-protection features for preventing unauthorized use of your webcam; Safe Money, financial transactions security, and PC Cleaner as well if you want those features you need to install the premium version of this software.

What We Like

  • Simple and easy interface.
  • Bunch of Unique features.
  • Protect your email.
  • Set up a scanning schedule.

What We Don’t Like

  • Must create a user account to activate the software.
  • Several features you see in the program aren’t free.
  • Can’t exclude scans by file extension.
  • Slow installation.

Bitdefender Antivirus-Free Edition

The free version of the Bitdefender antivirus tool isn’t as feature-packed as its paid version, but the good thing is it uses the same detection engine. Unfortunately, like Kaspersky and Avira’s free offerings, it’s not widely tested as a dedicated free product, which means we’ve had to rely on test results for other Bitdefender products that use the same malware detection engine which is a bit of a downside of this software.

furthermore, In this software there is a process that includes a threat scan of your system – you’re prompted to sign in or create a free Bitdefender account to use the software just like on the Kaspersky.

Bitdefender’s main interface is fairly simple and easy to use. One win window shows whether your protection is up-to-date or not, and the other one has a system scan. 

In addition,  There is also a settings menu that gives you access to a log of events including scans, updates, and detections, as well as quarantined files, websites, files, and directories that you wish to exclude from scanning – useful for software developers who don’t want their unfamiliar new files to be flagged as potential threats.

Despite this, it’s apparent that Bitdefender Antivirus Free Edition is a solid choice for anyone after a simple and effective free protection tool.

What We Like

  • Drag-and-drop file and folder scan.
  • Minimal design and easy setup.
  • Good malware detection performance.
  • Low false positive rate.

What We Don’t Like

  • Very limited customization.
  • The installation process is very long.
  • Requires a Bitdefender account.

Avira Free Security

Avira Antivirus Pro is a really solid choice for Windows users to protect this system. But there s also a free version of this software where you get so much with the free option. Avira Free includes the antivirus, the software updater, the home network updater, and a free VPN with an allowance of 500MB per month. All of these are separate applications connected via the Avira desktop app.

Furthermore, The installation process of Avira is very easy, with no attempts to sneak in other software, and no requirement for creating an account. Uninstalling, however, is a pain since there are so many different components automatically installed, and each one must be removed one by one.

The free version of this tool will scan your PC, and also offers real-time protection for your desktop. But it lacks protection from ransomware, web threats, email threats, and advanced cloud protection. It also lacks the improved PC cleanup feature for clearing out old files that you get in the Pro version.

What We Like

  • The password manager is included.
  • In-the-cloud antivirus process.
  • Fast Installation

What We Don’t Like

  • Additional features can be annoying.
  • It only protects Chrome and Firefox browsers.
  • Add-on components often require a fee to be fully functional.
  • Uninstalling is the software painful.

Avast Free Antivirus

Avast is an all-in-one antivirus software for protecting your system by getting hacked and stealing personal information. It helps you to protect from threats occurring via the internet, email, local files, P2P connections, and much more.

The free version of this Antivirus offers some of the most comprehensive protection available without a paid subscription. Avast not only gives you free access to its malware-fighting technology, but it also provides two bonus features that defend against other types of cybercrime as well.

There’s also an Avast Wi-Fi Inspector. An unsecured home network is like an open door for hackers. Avast Wi-Fi Inspector tests your network security to make sure there’s no way for hackers to break through this important first line of defense.

As a free program, you’ll be missing out on some features exclusive to the premium package just like on the other ones that I mentioned just before, It lacks the features like auto-scans and auto-updates. If you want those features you need to pay $70 per year for one Windows PC and $60 per year for one Mac. 

What We Like

  • Add-ons allow you to increase protection.
  • Great customizability.
  • Easy to use.

What We Don’t Like

  • Password manager and some other tools included are trials only.
  • Additional features require purchase.
  • Install other software while Installing.

AVG Antivirus Free

AVG has two major selling points. One is It has an impressively broad reach and this software will not only search for viruses and malware, but also helps block suspicious links, prevent suspect downloads, and keep suspicious email attachments from being used. This directly makes this app much a better choice for a family or elderly user on a budget.

The second benefit is AVG’s affinity with Google platforms. It has one of the better Android downloads and can work well on Chrome, too. The free version does offer scans for performance problems to see if you can speed up your PC, but the feature set is still best suited for users who don’t want to do very much except let their antivirus app run.

What We Like

  • Pop-up free silent detection mode
  • Effective detection of drive-by download malware

What We Don’t Like

  • Higher false-positive incidence than some rivals
  • Default install options include software you may not want
