Choosing an antivirus doesn't have to be a tedious process, even though it's true that there are hundreds of options out there. And also, all of those might seem the same at first. Still, there are ways to simplify your journey to finding the best free antivirus – and we're going to help you achieve just that.

One of the biggest online threats today is ransomware, locking your device and deleting all your data unless you surrender and pay. Then, there's malware infecting your system and keeping track of your online activity.

Phishing is also as active as ever. And all of this doesn't only affect Windows, as new breeds of malware for Android, macOS, and iOS have become highly aggressive as well.

A solution to this problem is an antivirus. In the best-case scenario, you'd go for one of the best premium-priced antivirus solutions. However, what if you don't want to pay? Can free antivirus applications protect you against today's ultra-powerful malware? Well, you might be surprised to know that they can!

Of course, free antivirus applications do come with certain limitations. And with this said, most of these limitations are bearable if you're an average home user. Or even better, if you're looking for a way to protect your devices proactively. These kinds of operations are supported by free antiviruses – which come with a varying degree of success.


If you're looking for a way to secure your device and your private (sensitive) data, make sure to use a VPN application. Coupled with an antivirus, a VPN can encrypt your incoming and outgoing data, protect you against hacking attempts, and boost your security and privacy online. Check out the best VPN services right now.

To ensure you get all of the information you need, we'll be taking you through three equally important sections of this article.

As you can see below, we'll talk about what to realistically expect from an antivirus, before listing the best free antivirus applications in 2020.

What to Expect From Free Antivirus Software?

Just like with any free-of-charge types of software, you can expect certain limitations. However, it's interesting to note that these limitations aren't overly severe. Since the competition in this field is quite rough, this has produced numerous viable options to use.

We should also mention that non-demanding home users will benefit the most out of free antiviruses. This includes those who want to remove malware and make sure they're adequately protected in the future. More advanced users will undoubtedly miss many features, and they're advised to go for a premium-priced solution.

With this said, here's what to realistically expect from free antivirus software.

What NOT to Expect From Free Antivirus Software?

As you can see, a reliable free antivirus can keep you protected against malware. We're sure that many of you will be happy to hear this – especially if you're battling a malware infection right now. So, does that mean you don't have to pay for an antivirus?

Well, there's a reason why there are both a free and a premium antivirus subscription. And also, there's a reason why we're talking about subscriptions here instead of one-time purchases. It all comes down to how much effort is needed for antivirus vendors to ensure that viruses don't reach your devices.

Now, here are some of the things that you can't expect from a free antivirus.

Can You Really Trust Free Antivirus Applications?

Well, that's a tricky question. The truth is that antivirus applications can collect plenty of information about your device and your Web browsing. That's absolutely needed, as your antivirus needs to inspect your device to provide the best type of protection. However, it's essential to keep in mind that any information collected should be anonymized.

We'd like to remind you of a recent situation with Avast, which has been accused of spying on its users and making a profit by selling that information. Avast has also suffered a breach earlier this year, which hopefully didn't expose its users' private information.

This is a reminder that we need to think about our privacy when using any type of software. With this said, there are no indications that free antivirus software is designed to act as spyware. In other words, you don't have any reason for concern – but we recommend exercising caution.

In terms of being protected against malware, keep in mind that free antiviruses can be hugely helpful and beneficial. However, these are still free-of-charge options, which means that your cybersecurity will always be limited somehow.

With this said, it's always better to have some protection instead of being completely exposed.

The Best Free Antivirus Software in 2020 - Our Picks!

Finally, let's talk about some concrete recommendations. Based on our hands-on tests and plenty of research, these are the 5 best free antivirus picks in 2020.

1. Best All-Around Free Antivirus - Kaspersky Security Cloud Free

Product Overview
Supported Platforms Windows, Android, iOS.
Real-Time Antivirus Protection YES (cloud-based scanning engine).
On-Demand Antivirus Scanning YES
Anti-Phishing Protection YES
VPN YES (200 MB/day).
Password Manager YES (15 entries).
Extras Deep Web scanner;
Visit / Download Kaspersky Security Cloud Free

Kaspersky is a well-known name in the cyber-security software world, with an experience of 20+ years fighting against malware. Therefore, it's not surprising to know that Kaspersky has an incredibly wide range of products – with a free-of-charge antivirus on offer as well.

What's surprising here is how much you'll get from Kaspersky without having to pay anything. This company's free antivirus is called Kaspersky Security Cloud Free, and as you can guess by its name, it goes much beyond what a typical antivirus can do.

Of course, the core part of this antivirus is its cloud-based engine. Its primary role is to scan your device against its signature database and remove any identified malware type. This engine is also used to protect you against phishing. And most importantly, Kaspersky typically comes out on top when tested by independent labs.

Kaspersky Security Cloud Free really shines when it comes to extras. Interestingly enough, these extras aren't advertised on its website for some reason. However, you will get a VPN service, a password manager, and a "Dark Web Scanner." The VPN is limited to 200 MB/day, which is quite generous for a free VPN service. The password manager is capable of storing only 15 entries and the Dark Web Scanner checks your e-mail address against the database offered by "Have I Been Pwned."

2. Best Windows-First Free Antivirus - Bitdefender Antivirus Free

Supported Platforms Windows, macOS, and Android.

On-Demand Antivirus Scanning YES
Anti-Phishing Protection YES
Password Manager NO
Extras Protection against scam websites.

You've probably heard that antivirus software will slow down your computer's performance. Well, this might still be true for some hugely comprehensive cyber-security suites. However, when it comes to antivirus software, things have drastically improved over the years - and we have Bitdefender's free antivirus to prove that.

For several years now, Bitdefender has been slowly shifting its approach. Today, this is an incredibly "silent" antivirus that tries to do everything on its own. Once you install it, you'll only get to see it when an infection is detected. Of course, you're always free to bring up its interface – but its most prominent feature is that it's practically invisible.

This also means that Bitdefender Antivirus Free is incredibly light in terms of its performance. We recommend it especially to those who have entry-level computers.

With this said, keep in mind that we're talking about an antivirus made for Windows primarily. There's a free version for macOS and Android as well, but these are very barebones (good enough for essential antimalware protection, though).

3. Most Highly Optimized Free Antivirus - Panda Free Antivirus

Product Overview
Supported Platforms Windows, Android.
Real-Time Antivirus Protection YES
On-Demand Antivirus Scanning YES
Anti-Phishing Protection YES
VPN YES (150 MB/day).
Password Manager NO
Extras Multimedia/Game mode; System optimization.
Visit / Download Panda Free Antivirus

Panda isn't as famous as other antivirus vendors found in this article. However, we're sure that's about to change, as this company has managed to produce an incredibly robust antivirus. So, let's see why this is one of the best free antivirus solutions in 2020.

First of all, Panda claims high-end malware detection rates. There's no difference here between what you get with Panda's free and premium tools. You can also count on real-time protection, and you can also schedule periodic scans. All of this is powered by cloud technologies, which means you won't hear your computer's fan spinning.

Panda Free Antivirus also comes with USB protection, so you can automatically scan any USB drive you plug into your computer's ports. When it comes to extras, Panda is offering a limited VPN, where you get 150MB/day. Not quite generous, but it should be enough to protect quick Internet browsing sessions while connected to public Wi-Fi networks.

Finally, keep in mind that Panda comes with a comprehensive free antivirus for Android. You get to protect your Android device from malware, check various permissions of individual apps, optimize your device's battery life, and even track your family members and different devices on a map.

4. Best Free Antivirus for Parental Controls - Sophos Home Free

Anti-Phishing Protection YES
Password Manager NO
Extras Parental controls; Remote management.

As this antivirus's name indicates, we're talking about a suite of cyber-security tools here. Called Sophos Home Free, this antivirus is designed for both individuals and families, giving you plenty of options to protect your children.

When it comes to its antimalware protection, Sophos is known to be incredibly successful at identifying the latest threats. It might not have the best detection rates, but it should be more than enough to protect home users (and maybe even businesses). You get real-time scanning, AI-powered threat detection, and on-demand scans.

When it comes to extras, parental controls are what takes the win. Sophos Home Free can be used on up to three devices to impose restrictions and prevent your children from visiting problematic websites. Thanks to a Web browser extension, anti-phishing is included as well. Sophos even tries to prevent you from visiting scam websites by using the SophosLabs database of compromised and dangerous online locations.

5. Best Cross-Platform Free Antivirus - Avira Free Antivirus

Initially known as one of the best free antivirus tools in terms of malware detection rates, Avira Free Antivirus now offers a comprehensive cyber-security solution. Knowing that it's facing fierce competition, this antivirus has been adding plenty of features over the years, including some unique options.

For example, you get a robust set of security-related features. Avira is backed by cloud technologies, which makes it incredibly light on your system's resources. It's also known for having one of the smallest footprints in the industry. And you get on-demand and real-time protection against malware.

In terms of protecting your privacy, Avira Free Antivirus comes with a limited VPN service (500 MB/month), and you also get a limited password manager. There's also a tool that scans your privacy settings and recommends options to close any security holes in your software. And let's not forget that Avira also includes a mechanism for optimizing your Windows PC by removing junk files, speeding up your boot time, and more.

Lastly, let's not forget to mention that there are significant differences in various editions of Avira Free Antivirus – depending on the platform you use. The most feature-rich version is the one made for Windows. Mac users are going to miss plenty of privacy-related features. And Android/iOS versions are pretty powerful on their own, coming with a VPN with a traffic limit of 100 MB/day.
