Best Free Antivirus for Windows in 2020

Top 8 Best Free Antivirus for Windows in 2020

Microsoft users need the best antivirus software to protect Windows 10 from malware attacks, keep their PCs running smoothly, and protect their identity and personal information online. Best Free antivirus for Windows 10 in 2020 has many features that allow you to manage mobile devices and monitor your PC’s firewall, software updates, and other functions.

However, some users do not want, or cannot afford, these additional features and may need to use free antivirus for Windows 10. If this is the case for you, you’ve come to the right place. We rated the best free antivirus for Windows 10 in 2020 based on their malware protection, system impact, usability, and useful additional features.

Bitdefender, however, remains the best free “install and forget it” antivirus for Windows 10. After installation, it takes care of itself and requires no user intervention. If you need to install antivirus software on your grandparents’ PC but don’t have time to update it, this may be the best solution.

Kaspersky and Bitdefender only offer the basics. If you want features like a password manager or a protected web browser, normally found in mid-priced paid antivirus software, then Avast Free Antivirus may be right for you. But its protection against malware is not as effective as the first two, and its impact on performance is greater.

Most of these companies also manufacture software for Mac and Android; For more information on these platforms, see our lists of the best antivirus for Mac and the best antivirus for Android.


List of Top 8 Best Free Antivirus for Windows in 2020

So which free antivirus for Windows 10 in 2020 would be best for you? Among these Top 8 Best free antivirus, Kaspersky Free Antivirus surpassed Bitdefender Antivirus Free Edition to take the first place.

Both provide excellent protection against malware without slowing down your system, but Kaspersky lets you schedule scans and offers a quick scan option.

  • Kaspersky, Free Antivirus
  • Bitdefender Antivirus Free, install it, and forget it.
  • Avast Antivirus Free
  • Windows Defender, Top Antivirus free pc windows 10
  • AVG AntiVirus Free
  • Avira Antivirus Free
  • Panda Antivirus Free
  • Malwarebytes Anti-Malware Free


  1. Kaspersky, Best Antiviruses for Windows 10

Kaspersky Lab does not advertise that it has a free antivirus product and does not make it easier to find the download page. Too bad, because it’s one of the best free PC antiviruses we’ve tested, with an understandable but clear interface, a slight impact on system performance, and Kaspersky’s unbeatable protection against malware. The only reason why we don’t give Kaspersky Free Antivirus a perfect score is that it doesn’t offer additional features.

Kaspersky Free Antivirus is considered one of the best free antivirus software available on the market in 2020. It has gained the trust of users and has built a good reputation in the market. The Premium version offers many interesting features which are mentioned below.


  • Vulnerability analyzer.
  • Protection for online shopping.
  • Better malware detection rate.
  • Frequent updates.



  1. Bitdefender Antivirus Free, install it, and forget it.

Like Kaspersky, Bitdefender Antivirus Free Edition offers nothing more than the basics, and its malware protection is just as good, although a bit more prone to false-positive detections. Its scans are lighter on the system than Kaspersky’s, but it offers fewer options – you can’t even schedule a scan. It is the best solution for users who want a security solution that allows them to install it and forget it for themselves or a loved one.

Its users love Bitdefender for its online protection and security. The range of security products provided by Bitdefender offers strong protection against spam, Trojans, rootkits, and viruses. You can install it on all your devices using the same license.

This antivirus works in the background without even slowing down the performance of your PC. The paid version is available for a 30-day trial period. The 2020 update for Bitdefender has improved its functionality by offering free services like protection against phishing and fraud.


  • Maximum protection against malware.
  • Very easy to use
  • Minimal impact on PC performance
  • Protection against phishing.
  • Blocking malicious URLs.
  • Analysis of demand.



  1. Avast Antivirus Free

The protection against malware with Avast Free Antivirus is a bit weaker. Still, it has the best assortment of additional products for free antivirus software, including a password manager, a browser with enhanced protection, and a network scanner. This antivirus is also highly customizable and offers limited access to the Avast VPN service. However, this caused quite a heavy system load in our tests.


  • Lots of additional features.
  • Highly customizable.
  • VPN client.
  • Appropriate protection against malware.



  1. Windows Defender, Top Antivirus free pc windows 10

The free antivirus software built into Microsoft Windows has finally reached the big leagues. Windows Defender won’t beat Bitdefender or Kaspersky when it comes to protecting against malware. Still, it defends itself well against other free antivirus products while offering low impact on system performance and a surprising number of additional features, including control parental and protection for all browsers. For the first time, we can recommend using Windows Defender as the primary antivirus.


  • Good protection against malware.
  • Integrated in Windows 10, 7, 8
  • Minimal impact on PC performance
  • Few additional functions.



  1. AVG Antivirus Free

AVG is Avast’s main competitor, decent but unspectacular while having a much smaller impact on system performance. But AVG AntiVirus Free has far fewer useful additional features than Avast Free Antivirus. The good news is that the many customization options for AVG and its file destructor are still available; the bad news is that there is no compelling reason to choose AVG over Windows Defender.


  • Low impact on performance.
  • File shredder.
  • Media protection against malware.

  1. Avira Antivirus Free

Avira Free Antivirus was the best free antivirus for Windows 10 a few years ago, before Bitdefender and Kaspersky jumped into the ring and Avast, AVG and Windows Defender increased their offerings. Avira’s malware protection is now halfway within the group. Its many additional functions are mostly just an introduction to paid service, and its impact on system performance is remarkably high. We appreciate the fact that you still have a wide range of customization options.


  • Highly customizable.
  • Many compliments.
  • Firewall manager.
  • Protection against poor malware.
  • Slightly high impact on performance.



  1. Panda Antivirus Free

Protecting Panda Free Antivirus against malware is an enigma. We appreciated the high degree of customization of this antivirus and its attractive interface. We didn’t like the constant announcements from other Panda products, attempts to hijack your web browser, and the fact that, unlike any other free antivirus software for Windows 10, Panda doesn’t allow you to opt-out of automatic collection of system data.


  • Very customizable.
  • Moderate impact on performance.
  • VPN client.
  • Real-time protection.


  1. Malwarebytes Anti-Malware Free

Malwarebytes Anti-Malware Free is not an antivirus software. Rather, it is a malware removal tool (Malwares). This tool cannot protect a PC from infections, but it does a great job of cleaning up malware that is already in your system. Also, it does not interfere with any antivirus software already installed. We recommend Malwarebytes Anti-Malware Free as a supplement to any other antivirus software.


  • Complements antivirus software.
  • Removes adware and other unwanted software.
  • Install the trial software for the paid version.
  • Manual definition updates.
