AVG has a free antivirus, and also a paid option. The free option has malware scans of all kinds, real-time security updates, blocking of links, downloads, unsafe attachments, and PC performance analysis as well.

It is somewhat more limited than the paid option, but it offers almost exactly the same results as AVG Free Antivirus.

Bitdefender has in its Internet Security one of the best antiviruses on the market, at the level of those mentioned above.

And as a free antivirus option, they also offer the one at hand: Bitdefender Antivirus Free Edition.

Obviously, like all antiviruses with a paid version, this one has some shortcomings, such as, for example, that it does not have 24/7 support, or that it does not offer us a VPN integrated into the computer security software. But it does have web attack prevention, smart antivirus, anti-phishing system, online fraud and other really interesting features.

Without a doubt, a great option to have our equipment protected at a basic level.



Once again, with Kaspersky we have two options: free antivirus, and paid solution.

Windows Defender comes pre-installed on all Windows 10 computers.

It is the free antivirus of the Microsoft company, and it is curious because it is one of the best and you do not need to install it since it comes from the factory

In fact, in the latest AV TEST results, it receives the highest score in all sections except for the one corresponding to performance.

Of 6 points that he could have at most, he stays with 5.5.

But at the security level it obtains the maximum, and also in the usability section thanks to the ease of use of the program.

However, it has shortcomings, such as the browsing filters offered by other antiviruses for integration into the Google Chrome web browser and others.

If you have a Windows 10 operating system, then you have Microsoft Windows Defender installed out of the box, which is why you have a “free” antivirus.

All you have to do is go to settings, updates and security and Windows security. Once we are at this point we can control Windows Defender.

To check that all the services are active, you just have to open the Windows Defender Security Center, from which you can check if the following services are active or not:

Virus and Threat Protection
account protection
Firewall and network protection
Application and browser control
device security
Device health and performance
family options
As in the image, all services should have a green tick indicating that they are active and prepared for any threat.


Is free or paid antivirus better?

One of the most important aspects of an antivirus is its database.

The companies behind these solutions dedicated to computer security have to constantly release updates to these databases with the information corresponding to new malware threats and keep themselves updated.

Thus, an antivirus will be able to detect new threats that reach the computer.

But the effectiveness with which antiviruses act against malware, the impact on performance and, obviously, the ease of use based on its interface and options is also important.

In this sense, free antivirus and paid solutions compete on equal terms.
