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

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
Firewall and network protection
Application and browser control
Device health and performance
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.
