Windows Defender is malware protection that is included with and built into Windows 8 and Windows 10. This software helps identify and remove viruses, spyware, and other malicious software. Windows Defender runs in the background and notifies you when you need to take specific action. However, you can use it anytime to scan for malware if your computer isn’t working properly or if you clicked a suspicious link online or in an email message.
*A similar product called Microsoft Security Essentials is available for Windows 7 and Windows Vista computers. Please see below for installation instructions.
