Windows Defender SmartScreen

Windows Defender Exploit Guard Network Protection extends the functionality of Windows Defender SmartScreen. Windows Defender SmartScreen, which is built into Windows 10, protects against phishing or malware Web sites and stops a user from downloading potentially malicious files. SmartScreen requires the Edge or Internet Explorer browser.

To determine if a site is malicious, SmartScreen analyzes the Web page for suspicious behavior, and it checks sites against a dynamic list of reported phishing and malicious software sites.
