Is Windows Defender part of Windows 10?

Yes, Windows Defender is part of Windows 10. Windows Defender is Microsoft’s anti-virus solution built into the Windows 10 operating system. It helps protect PCs against viruses, spyware, and other malicious software.

Windows Defender is updated automatically using Windows Update, so you don’t have to do anything else to keep it up to date. It is also free, so there are no additional charges for upgrading or downloading the program.

Windows Defender is designed to protect your PC against malware, such as viruses, worms, Trojans, rootkits, and other malicious software. It does this by scanning your system for known malicious files or components, and then preventing them from running or being installed on your computer. It also monitors for suspicious activity on your computer, such as email scams and online threats, and can help protect against phishing and other frauds.

Windows Defender also provides real-time protection, meaning that it will automatically scan files when they are opened or downloaded, and can block malicious files before they have a chance to run on your computer. It also sends out periodic updates to its virus definitions to keep you protected against the latest threats.

The program also includes ‘on-demand’ scanning options, so users can perform quick or full scans of their computers whenever they choose. This feature can be used to check for new viruses or other security threats that may have been missed by the automatic protection.

Windows Defender also has advanced features, such as automated remediation from Microsoft, which can help fix any security vulnerabilities that are found on the system. It also offers a ‘Quarantine’ option, which can be used to isolate dangerous files and help prevent them from entering your machine. Finally, it has features that allow you to customize the program and set rules for what type of files and activities it should detect and block.

Overall, Windows Defender is an effective tool for protecting your system against viruses and other malicious software, and since it is built into Windows 10, it’s easy to use and always up to date with the latest security definitions. It’s also completely free, so there’s no need to purchase additional software to keep your system secure.
