SmartScreen Filter helps to protect you from online threats
Internet Explorer 9 is designed to help protect you from evolving web and social engineering threats. Whether it's a link in email that appears to be from your bank, fake notifications from social networking sites, search results for popular content, or malicious advertisements—you name it, someone's trying it. With SmartScreen Filter, you can browse with more confidence knowing you have better protection if you're targeted by one of these types of attacks.
SmartScreen Filter helps combat these threats with a set of sophisticated tools:
Anti-phishing protection—to screen threats from imposter websites seeking to acquire personal information such as user names, passwords, and billing data.
Application Reputation—to remove all unnecessary warnings for well-known files, and show severe warnings for high-risk downloads.
Anti-malware protection—to help prevent potentially harmful software from infiltrating your computer.
If a malicious website is detected, Internet Explorer 9 blocks the entire site, when appropriate. It also can do a "surgical block" of malware or phishing hosted on legitimate websites, blocking malicious pages without affecting the rest of the site.
Smartscreen Filter also works with Download Manager to help protect you from malicious downloads.
Potentially risky downloads are immediately blocked.
Download Manager then clearly identifies higher risk programs so that you can make an informed decision to delete, run, or save the download.
We recommend that you turn on SmartScreen Filter. You can turn it on or off at any time. You can also help improve the web for everyone by reporting suspected malicious sites.
