windows defender not working in windows 11

While new security bugs and viruses are still being discovered in Windows on a regular basis, Microsoft Defender is constantly updated with virus definitions and security features to keep your system well protected. Windows Security protects your Windows 11 systems that have no other antivirus protection. It is a free antivirus and anti-malware tool that is bundled with Windows 10 and Windows 11 OS that protects your device and data from unwanted malware. However, Windows is not totally defenseless, it has its own built-in anti-malware program called Microsoft Defender Antivirus (also known as Windows Security) that protects against all types of malware and viruses. The sheer number of devices that are using Windows and its huge market share are the reasons that Windows is targeted by attacks and malware more than any other operating system. Windows is more prone to malware and viruses than any other platform out there, and yet, it is the most popular and widely used desktop operating system on the planet.
