The world of security has evolved. 

We are no longer dealing with the simple threats of viruses that came through the physical formats of many years ago.

Now we must be alert to malware, adware, and any other malicious software that can seek to make money at the cost of our suffering.


Fortunately, antivirus programs have also evolved and offer security measures that know how to keep these threats at bay (more or less). 

And there is another good news: there is a free antivirus that covers most of the needs of the user base. 

Before we go into the details, I found this very useful video. Please watch the first 60-second of this video.

In this video, you’ll know the top 5 best free antivirus software for both Windows and Mac with ease of use, system impact, and overall effectiveness is the most important factors.

Let’s look at what options we have for Windows.

Top Best Antivirus and Security Tools for Windows

A Windows system without antivirus and one with an antivirus installed can be very different, and precisely in that difference is where we have to look for benefits or drawbacks. We can start with the essentials: An antivirus should affect as little as possible the overall performance of the computer.

There are tests to measure the efficiency of antivirus and its efficiency in detecting threats, such as the PC Mark test that start with a score of 100 that indicates the performance of a computer without the software security installed and decreasing as it measures the “slowing factor” of the Antivirus. The lower the score, the better the antivirus.

In terms of efficiency in detecting the threats, we can choose to look at the virus bulletin VB100 test. Completely independent of any antivirus developer, this test tests these programs to see if they detect certain threats or not.

Let us see the list of eight best Antivirus now.

Avast Free Antivirus 2021

Avast is one of the most used antivirus solutions with a community of 230 million users worldwide. The Avast optional tools include a password manager and a utility that cleans our browser of adware and malware. Avast score on the PC Mark Test is 99.3% and exceeds the VB100 test with 86.1% efficiency.

Avira Antivirus

Avira is another very popular antivirus, with a score of 99.7 on the PC Mark Test. In addition to constantly analyzing threats from your private cloud also has an extension of browsers, support forums where the community can participate, and other tools from which to control all devices.

Avira is one of the most successful antiviruses in the VB100 test with an 87.05% efficiency and has no less than 99.7% in the PC Mark performance test. Another well-punctuated option to take into account.

Online Panda Security

For specific analysis from the browser itself, we have Online Panda Security available to us. We can download the free tool for a scan of the system or opt for the advanced options for 38.49 euros. It does not score too well on the PC Mark with 98.7 points.


Virustotal does not analyze our computer itself, but it is a website where we upload files that we consider suspicious for the servers to analyze. Created in Malaga, the virus total website was acquired by Google four years ago.

AVG Free

Another anti-virus well known by Windows users is AVG, whose free version is compatible with Windows 10 and serves as the basis for the company to promote its AVG Performance payment tools (to improve PC performance) And with the professional AVG Ultimate version.

AVG is the antivirus that scores better in the PC Mark test, with a 99.8; And exceeds the VB100 test with an 83.1% efficiency.

BitDefender Free

Bitdefender is one of the most discrete antivirus software in Windows. Its interface is count in the system start bar and annoys the right thing to scan and detect threats. In addition, it also boasts of not including adware in your installation and does not affect the performance of Windows. It enjoys a 99.5 in the PC Mark test and surpasses the VBulletin test with an 85.4% efficiency.

Malware Bits Anti-Malware and BitDefender Adware Removal Tool

In many cases, the objective of the user is not to do a complete analysis of the system but to eliminate a threat that has already been located. For these cases, it is very good to have on hand tools like Bitdefender Adware Removal Tool or Malwarebytes Anti-Malware. As they are specific analysis tools and do not have to run them constantly in the background, they do not have performance tests.

Windows Defender

How would we finish the list without mentioning that Windows has its own antivirus? Windows Defender offers basic protection against network threats and has the best integration with the Microsoft operating system. The result of passing the PC Mark test with Windows Defender enabled is 98.8 points.
