In recent years the amount of viruses and malware has increased dramatically and we all try to protect ourselves as much as possible to avoid seeing our stolen data or our unusable PC. But what is the best free antivirus for Windows 10? In this guide we are going to see just that.

What is the best free antivirus for Windows 10?

We often hear that the best antivirus is you and that’s true. Everything (or almost) that happens on your PC happens after you have performed certain actions. So first of all to make your PC more secure avoid downloading software from untrusted sources and not opening email attachments unless they come from safe sources.

This is because often downloading from untrusted sites you can run into software that has the intent to install various malware , worms and viruses.

After adding the first layer of protection (the most important), let’s talk about programs that help you filter the files that can escape you.

Windows Defender

With the release of Windows 10 (read how to install Windows 10 for free), Microsoft introduced Windows Defender as a pre-installed antivirus. This is the antivirus that I recommend to everyone for Windows 10. It is often thought that being free this is not a good antivirus. Well, that’s not quite the case. Windows Defender is a good antivirus and various tests prove it in comparison with other antiviruses.

In addition, this antivirus is perfectly integrated with the system and is therefore optimized to not slow down your PC or make it slower on startup.

This antivirus does not install various browser extensions which actually only put you in danger and slow everything down.

To make the protection complete if you use this antivirus, I suggest you also install Malwarebytes of which you will find more information in the next paragraphs.

Avira (best antivirus of the month)

A good antivirus also available in a free version is Avira. This antivirus is among the best ever and allows 360-degree protection.

Avira is often named among the best antivirus of the month by AV-TEST and is very light so it will affect the performance of the system to a small extent.

Importantly, delete the browser extension that the antivirus automatically installs you.

If you want to buy the PRO version of Avira you can do it from the official website at a price of €34.95 per month.


Now let’s talk about an excellent anti malware. We have all heard of Malwarebytes at least once. It is the most popular malware removal software .

Malwarebytes offers a free version that allows you to remove all malware from your system but unlike the Premium version with the free version you will have limited real-time protection.

In fact, with the Premium version of Malwarebytes you can have all the alerts in real time on any threats.

If you want to buy the Premium version of Malwarebytes you can do it from the official website at a price of around 34 euros per year.

Best free antivirus for Windows 10: conclusion

We have seen which are the best solutions to have a secure system with Windows 10. The solutions mentioned are very valid for various reasons which are performance , reliability and continuity. All at zero prices or very low if you want to buy the Premium version.

But remember, as mentioned at the beginning of the guide, the best antivirus is you so always try to avoid not recommended sites and not download files from unknown sources.
