In the early 2000s, Windows operating system security relied heavily on third-party antivirus software. In 2009, Microsoft first introduced Security Essentials as a free antivirus software specifically for Windows PCs. Over the years, Microsoft has developed Security Essentials into a powerful and comprehensive product, even surpassing other leading antivirus software in AV-TEST certification.
With Windows 8, Microsoft replaced Security Essentials with Windows Defender. By the time Windows 10 launched, Microsoft had turned Windows Defender into a generic brand for several security products, and all Windows 10/11 PCs now come with Windows Defender Antivirus built in.
Microsoft recently shared a blog post explaining how Microsoft Defender Antivirus protects Windows 10 and Windows 11 users from keylogger and screen scraper malware. Keylogger malware can record every keystroke, clipboard data, and screenshots on a PC, while screen scrapers can “stealthily” take pictures and record videos of what’s happening on a user’s PC screen.
Microsoft has revealed that Microsoft Defender Antivirus now uses AI, ML algorithms, and the cloud-based Microsoft Intelligent Security Graph to block malware within milliseconds of detection. Additionally, Defender AV can even analyze behavior and process trees to stop fileless malware and human-made attacks.
Here's how Windows Defender Antivirus protects Windows 10 and Windows 11 users from keylogger malware, according to Microsoft:
