SmartScreen is a set of sophisticated technologies to help protect you from malicious websites and
programs. Whether you’re downloading or running a new program on the desktop, SmartScreen has you
covered. SmartScreen continues to provide protection from phishing and socially engineered malware
attacks using URL and application reputation and removes unnecessary warnings for programs and
publishers with an established reputation. To add another layer of protection, SmartScreen is now integrated
with program launch to screen programs downloaded from the web. It also shows new warnings before
higher-risk programs can run and will block known malware.

effective: by loading approved antimalware drivers during the boot process, antimalware software can start
from a known good state and continue its vigilant watch over your PC from that point on.
