It is something that we have already commented on countless occasions, we refer to the need to use an antivirus on our Windows PC. This protects us from the vast majority of threats that can threaten our computer at this time. In addition, they will also serve us to increase the privacy and security of stored personal data. For example, for this we can use Windows Defender , Microsoft‘s proposal for its operating system.
This security solution came from the hand of Microsoft at the same time that it launched Windows 10. It is true that over time it has not stopped growing and improving, so the confidence of users is increasing as it receives new updates. However, there are still those who do not want to use this Redmond software. The reasons can be of various kinds, so below we will see some of the most significant.

Until a few months ago, this was an antivirus integrated into Windows 10 that could be permanently deactivated through registry adjustments. But that is no longer allowed, so we will have to use third-party applications. At the same time, from the antivirus itself, we can deactivate it temporarily if we have to carry out a specific action, such as installing a software marked as dangerous. But be that as it may, these are some of the main reasons why you should not use Windows Defender right now on your computer.

To use another third-party antivirus
Despite the fact that Windows Defender is an antivirus that has improved substantially over time, many still distrust it. They prefer to make use of the solutions of a lifetime through companies with more experience in the sector. That is why we can use third-party security programs and install them in Windows. What’s more, in the event that Windows Defender detects another antivirus, it deactivates itself and stops working.
For privacy issues with Microsoft
One of the big problems that many users have with Windows 10 is derived from privacy and telemetry issues. That is why this is sometimes extended to the scanners of our data that Windows Defender performs. Therefore, some consider that to safeguard their privacy when using Windows to the maximum, they prefer to disable the operation of the mentioned program.
They don’t want an antivirus on the PC
Everyone with their own computer and their own Windows system does what they please. Therefore, if for whatever reason you decide not to use an antivirus that blocks certain file downloads or that does not let me access certain websites, Windows Defender is a stumbling block. The reason for this is that it is implemented in a non-chosen way with Windows itself, and also running at full performance . Therefore, these users are fully entitled to want to disable Microsoft’s security solution.
They don’t trust Windows Update updates
Finally, we will say that one of the great handicaps that Microsoft faces with Windows 10, are the updates that come to us through Windows Update . In addition, the aforementioned antivirus is also updated in this way, with the failures that sometimes occur, sometimes serious. That is why others may decide to stop using this protection program to avoid potential update errors.
