AMSI (Antimalware Scan Interface) in Windows 10 can help protect users from dynamic script-based malware and other forms of cyberattack. AMSI is an interface standard that allows applications and services to integrate with any existing antimalware product on your PC. Those apps can call the new Windows AMSI APIs at any time to scan for malware.
