Though macOS malware is on the rise, most malware developers and other dangerous hackers choose to target Windows because it has so many more users. That isn’t because Windows is an unsecured operating system, but simply because it’s the most popular one. Windows is vulnerable to many more threats than macOS, because Windows machines tend to be targeted more, and Windows Defender is Microsoft’s answer to these dangers. Like other antivirus tools, Microsoft Defender scans your system for malware and monitors your software for unusual behavior. Windows Defender, or Microsoft Defender Antivirus, is an antivirus tool that comes preinstalled on Windows 11 and 10 computers.

Viruses and malware are just some of the threats seen online. Microsoft won’t let you go without protection, sin ce without a security program, Windows users are severely at risk from the wide world of online threats. Microsoft Defender assumes primary responsibility for your computer’s security until you install a third-party antivirus tool, at which point Microsoft Defender may relegate itself to the background. You can expect Windows Security to provide ample protection against computer viruses as well as other types of malware such as ransomware, spyware, and Trojans. As part of the Windows Security suite, Microsoft Defender Antivirus performs these services for free, and Microsoft updates it daily to counter new threats.
