Protect your PC: these are the best free antivirus

It is always good to have a layer of security with more and more malware circulating on the Internet.


Are you serious about the security of your PC ? An antivirus is not a bad idea. The best thing is that there are very good free options today.

That’s how it is. Uninstall that trial version of McAfee and review with us the best free antivirus for Windows.

Windows Defender

If you have Windows 10 or Windows 11 , you already have a pre-installed antivirus.

Microsoft’s antivirus gives you at least a layer of protection, but it lacks some features that more comprehensive products do. If your PC usage is basic and you never open suspicious emails or access disreputable sites, chances are you’ll be fine with Windows Defender alone .

Avira FreeSecurity

It is a security suite that includes more than antivirus . There are interesting options like a VPN, password manager, among others.

However, this antivirus uses a “freemium” model, so you will have to pay if you want 100% of these products.

*Avira was acquired by Norton in late 2020.

AVG AntiVirus Free

Another good product that relies on the “freemium” model. There are good options, but AVG wants you to end up going Premium, so it shows you options not available (unless you pay) as part of the menu.

This antivirus stands out for its startup search, which can be quite useful, but it’s not that fast.

Still, a good option with good results when it comes to removing malware.

*AVG was acquired by Avast in 2016.

Kaspersky Security Cloud Free

Kaspersky shines with this product, which also has versions for Android and iOS.

A great protection that could be measured without problems with some paid products, except for one detail: this free version does not provide direct technical support to users.

Avast One Essential

A very complete option when it comes to free antivirus with versions for Mac, iOS and Android in addition to Windows .

Avast One Essential stands out for its malware detection and privacy options, but only for ONE device. However, the best options are (obviously) reserved for the commercial version.

*Avast announced that it will merge with Norton in 2021.

When should I opt for a commercial antivirus?

We refer to a payment option. Paid antiviruses have more robust options and a greater attention to technical support. They also have features that will allow you to manage your WiFi and control the activity of minors regarding risky sites.

If you are looking for antivirus for your company or business, it would be best to opt for a paid option that gives you the necessary support.
