Do you want to protect your computer from viruses? Then the Windows Defender integrated in Windows 10 should always be active!

Windows Defender is normally activated automatically. This detects viruses and malware and prevents their installation and execution so that your computer is protected. However, it can happen that it deactivates - for example, if you have installed another antivirus program on your computer in the meantime. In this case, you have to reactivate Windows Defender manually. We'll explain very simply how this works on Windows 10.

Follow our step-by-step instructions or take a look at the brief instructions ..

1st step:
