If you use Microsoft Defender as an antivirus, there is something you have to take into account: its offline operation leaves a lot to be desired compared to other antiviruses.
User security is something that a large number of companies care about and, in fact, over the last few years we have seen that different security solutions have emerged. Microsoft Defender is the security proposal that comes with Windows, regardless of whether it is the new Windows 11 or Windows 10.
So far, Microsoft Defender has been able to defend itself against competing antiviruses, and Microsoft has put great effort into making it an antivirus capable of protecting users from any threat. To achieve this, they have developed an infrastructure that supports Microsoft Defender.
This infrastructure is based on the cloud, allowing Microsoft Defender be a much more efficient and functional antivirus at a general level. But it has just been discovered that relying on the cloud to identify the different viruses is not a successful solution and, in case of running out of internet, the capabilities of Microsoft Defender pale.
It has been the AV-Comparatives company that has been in charge of making this come to light and it has done so testing a series of antiviruses to find out their capabilities, both online and offline. The results housed in this analysis of these antiviruses are quite worrying.
The Internet is the key to the proper functioning of Microsoft Defender as an antivirus
Tests conducted by AV-Comparatives and collected by Techspot have been made with a computer running the operating system of Microsoftbeing the version chosen Windows 11 instead of Windows 10. Microsoft Defender has not done particularly well and, is that, when there is no internet connection, it is in third place starting from the end.
Behind Microsoft Defender with a score of 68.9% are both Panda with 52.8% and Micro with 41.1%.. The first places are reserved for VIPRE with 94.9%, Total Defense with the same score and Avast with 93.9%. But the interesting thing is that when the internet connection is turned on, the behavior of Microsoft Defender changes.
By having the internet connection and, therefore, Being an online antivirus, the Microsoft Defender score is one of the highest, being 99.99%. Bearing this in mind, there is a fairly clear conclusion in this analysis and that is that Microsoft has focused too much on creating a structure behind this antivirus and has neglected its operation in offline situations.
