Dear friends of the forum I have recently installed on my PC equipped with Windows 10 - 64 Bit the antivirus Kaspersky 2021. Going now in the "security" section of Windows, however, I noticed that Windows Defender is still active (as you can see in the screenshot below). So now I have two active antivirus: Microsoft's Windows Defender and Kaspersky. I would like to ask you if it is preferable to deactivate Windows Defender after having installed the Kaspersky antivirus. Thank you all for your interest
