Best Antivirus 2022: Updated Tests for Windows PCs

Best Antivirus Guide 2022

In both tests (AV Test and AV-Comparatives), are taken into account to prepare the final ranking, main points such as:

  • Real-time protection
  • Removal of malware
  • Performance

In all tests, computers are running Windows 10 with all available security updates installed, and all programs (including antivirus) are also up to date. These are basic security measures that you should also use on your computer.

You will also notice that in some tests, not all antiviruses are included. This is an individual option for each company to decide on which test the product will be evaluated.

Real-time protection

One of the most important tests, where antiviruses are subjected to real threats, newly discovered and need to keep the system safe, blocking access to infected sites, downloads from suspicious sites, malicious email links and other various ways of spreading malware.

Real-time protection

Highlights for Kaspersky and Bitdefender, which managed to block 100% of threats without requiring any user action.

Avira Antivirus also did well in the test; it blocked 100% of the threats, but it identified a legitimate file as a threat, an event known as a “false positive,” which we will explain further below.

Removal of malware

Equally important, the malware removal test evaluates how the antivirus behaves when installed on a previously infected system. It must be able to identify and remove as many threats as possible.

Removal of malware

A highlight for Kaspersky was reaching 99 points, followed by Avast, Avira, and Bitdefender, all of them with 94 points. F-Secure Antivirus was in the last position, with 75 points.

One of the great advantages of investing in a paid antivirus is the additional features and protection. An excellent extra feature is the availability of an infected system recovery disk.

Using a pen drive or a DVD, you can check for virus removal even when Windows no longer starts correctly, or when infections are blocking the installation or use of the antivirus.

Performance: What is the lightest and most efficient antivirus?

Performance testing is especially important for users who have a computer with fewer resources.

It evaluates the impact of installing an antivirus on the use of the system in common tasks, such as browsing the internet, copying files, and unzipping a file. The objective is not to leave the slow computer even when doing file checks.

In the graph, the smaller the bar, the less interference the antivirus performs, so it is better.

Among those available and used here in Brazil (ignoring K7 Antivirus), ESET Antivirus obtained the best result with 6.5 points, followed by Avast and AVG with 6.7 points, followed by Bitdefender (6.9 points) and Kaspersky (7.2 points).

What is the best paid antivirus in 2022?

Based on official tests and on our professional experience, working since 2007 with IT support for home users and companies of all sizes, Kaspersky Total Security is the best paid antivirus to protect your computer from viruses and other threats, followed by Bitdefender and Avira.

Differences between paid antivirus and free antivirus

In particular, we always recommend to our direct customers and now to you readers of the site, the purchase of one of the best antiviruses of 2022, in the paid version, for complete protection of the computer against viruses and other threats, but there is one detail that needs to be clarified.

The antivirus engine (engine) is the same in both the free and paid versions. Your computer system is not unprotected because you use a free antivirus. The difference is exclusively in the additional functions and in the fact that most of them, when using the free version, display a small daily offer for the paid version.

Using Kaspersky as an example, the free version offers essential protection against viruses, suspicious websites, and other threats. It’s the basic level of antivirus protection you need to have on your computer.

With Bitdefender, Avira, and Panda, the same thing happens. Unfortunately, Norton is the only one that doesn’t offer any free versions of its antivirus for users.

Therefore, in the following list, we will only have small changes, and I will explain the reason for each one of them, for you to better understand the changes.

What is the best free antivirus for 2022?

If you definitely don’t consider or believe that you don’t need a paid security solution, Kaspersky or Bitdefender Free is the best free antivirus for you to install on your computer, which offers essential protection for Windows in the free versions. Check out the top 5 free antiviruses below.

Ranking of the best free antivirus software for 2022:

  1. Bitdefender Antivir Free Edition
  2. Kaspersky Security Cloud Free
  3. Panda Free Antivirus
  4. Avira Security Free
  5. Avast Free Antivirus/AVG Antivirus Free

We put Bitdefender in front of Kaspersky in the free version as it has an advantage, which is the fact that it does not display daily advertisements for the paid version of the product, which, despite being a common practice, can be uncomfortable for many users.

Panda entered the list in place of Norton, which does not have a free version of its antivirus. Panda Free Antivirus, as it is called, offers good levels of protection, is very simple to use and does not interfere with system performance.

Avira remains a good option, while Avast and AVG are the same company. Basically, it just changes the antivirus layout. They all offer good levels of protection and basic security features for the system.

If you have difficulties with the procedure, we have a practical guide that teaches you how to download and install an antivirus using the free version of Kaspersky as a reference, but the procedure is similar to the others.

Can I use two antiviruses to increase security?

This is a basic mistake that many users make. Basically, when you install two antiviruses on your computer, it’s as if one is going to interfere with the actions of the other and not increase security, as some believe.

Technically speaking, an antivirus needs to have access to the Windows core, the so-called kernel of the system. By the way, Windows 10 has an integrated free antivirus called Defender. Whenever you install a third-party antivirus, it is automatically disabled to avoid conflicts.

The same happens when you already have another antivirus installed. When you try to install a second option, it is very likely that you will be prevented by the current antivirus, or at least receive an alert of possible problems.

Is there a difference between choosing a notebook antivirus?

Yes, there is. The vast majority of notebooks still use slower HDs than desktop computers.

That’s why you should always evaluate the issue of Windows antivirus performance and impact.

A lightweight and efficient version like Kaspersky Antivirus, which is a paid antivirus with minimal impact and great protection, may be the best choice in this case.

How to keep my computer virus free?

After reading the complete guide, best antivirus software, choose the best option for you, whether it’s paid or free.

If you are in doubt about a paid solution, most offer a trial version, where you can use the product with all its features for at least 30 days.

In addition to choosing the antivirus, it is essential that you keep the operating system with all security updates applied and with all programs and plugins updated to avoid system breaches.

Free antiviruses usually don’t have a firewall that works as a barrier between the system and the internet, controlling what may or may not have access to the network. Since Windows XP already incorporates this functionality with security, it is important that you leave it activated.

Be careful when accessing third-party links on social media and in your email. Stay alert with miraculous offers.

Finally, we recommend that you read the Internet Security Brochure, offered free of charge by the Center for Studies, Responses, and Treatment of Security Incidents in Brazil ( to increase your knowledge about computer security and safe internet browsing.
