To help better protect consumers from malware in Internet Explorer 9, Microsoft has introduced a rating called Download Reputation. Download Reputation in IE9 will help users distinguish between well-known downloads and those that are a higher risk to their computers.
Internet Explorer 9 provides the first download manager with integrated SmartScreen malware protection and introduces SmartScreen download reputation. SmartScreen download reputation is a groundbreaking browser feature that uses reputation data to remove unnecessary warnings for well-known files, and show more severe warnings when the download has a higher risk of being malicious.
Users today are often conditioned to ignore generic warnings that are shown for every download. Other browsers show the same warning whether a file is an extremely common program or a piece of malware created literally minutes ago.
Internet Explorer 9 is the only browser that uses download reputation to help users make safety decisions. SmartScreen Download Reputation allows IE9 to remove warnings for commonly downloaded programs and show actionable warnings for programs that are higher risk.
In IE9′s Download Manager you’ll see there’s a clear warning for the higher risk program and there’s no warning at all for the well-known program. With Download Reputation in IE9, consumers can then make better safety decisions.
