With continuous internet usage and increased device connectivity, internet security is no longer optional. It is imperative to secure your computer or laptop with the best possible antivirus—b that doesn’t necessarily mean you’ll need to pay large sums for them.

After researching all available options, we have brought you the best free antivirus software in 2021.

  1. Microsoft Windows Defender

What many users don’t know is that Windows 10 comes with its own antivirus; Microsoft Windows Defender. The best part is—it’s free and effective. Although many users won’t feel the need to go beyond this protection, if you do think you need more—read on.

  1. Kaspersky Security Cloud Free

The best overall appears to be Kaspersky. With its overall efficient protection, even in its free version, it has been getting high scores when tested by independent labs. It doesn’t slow down your system either.

  1. Avast Free Antivirus

Avast has been providing top-notch security for Windows, with great ratings and without any fees or payments required. It protects against internet and email threats, malware, and viruses. The one aspect that probably goes against it is that it appears to slow down your system at times.

  1. AVG Antivirus

Great at detecting threats and malware, AVG has many great features. It performs regular computer scans and real-time protection on the web. 

  1. Bitdefender Antivirus

Yet another great software to protect your precious data—Bitdefender has consistently shown great performance. It monitors the threats to the system in real-time, yet doesn’t bother the user and only turns up when needed. It won’t weigh on your wallet either-—it has a very effective free version.

  1. Avira Free Security

While protecting from the usual cyber threats and malware, Avira also provides a free VPN to protect the privacy of the users.


The list doesn’t get much better than this. Ultimately, the best protection you’ll get is from paid-for antivirus software. That doesn’t mean the free versions don’t work—they do provide reasonably good security against malware and other threats. Although you might want to check their consumers’ privacy policy beforehand to protect your personal data.
