SmartScreen Application Reputation is a new safety feature introduced in Internet Explorer 9 that provides you with more relevant information about whether a downloaded program is a higher risk to your computer. Information about an application is checked against our online service to determine its reputation.
You are shown warnings only when a downloaded program does not have established reputation. Application Reputation is a feature in Microsoft Edge for unsafe downloads. As of Windows 8, it is also a feature in Windows, warning users when executing unsafe files from the Internet. Microsoft Defender SmartScreen uses information from Internet Explorer, Microsoft Edge, and Windows users around the world as well as anti-virus results, download volumes, download history, URL reputation, and many other criteria to determine the likely risk of downloaded programs.
For example, programs that are downloaded by many users over a long period of time without a history of malware are not likely to be malicious. This warning indicates that caution should be taken before running the downloaded program, especially if the download is not digitally signed.
Does this warning mean the file is malicious and will harm my computer? No - the Application Reputation warning is not an indication that the download is malicious. However, for the average Internet Explorer, Microsoft Edge, and Windows user this warning is usually associated with a download that may have a higher risk of being malicious.
There are a number of factors to take into consideration before running a program flagged by Microsoft Defender SmartScreen.
Is the file digitally signed by a software publisher? The application reputation warning dialog will indicate if the file is not digitally signed. Most malicious programs are not signed by a publisher so be careful if you choose to ignore the warning.
How were you directed to this download? Was the download link unsolicited, such as from an email, instant message, or social networking post? Would you expect this program to be an uncommon download? If you thought you were downloading a popular game or other program, you should be suspicious that many other Internet Explorer users have not also downloaded the program. There are industry best practices for application developers that will affect your download's reputation and help ensure reputation is established and maintained.
If your program is not digitally signed, reputation cannot automatically be shared across different versions and builds. To help establish your application's reputation, consider doing the following: Digitally sign your programs with an Authenticode signature Reputation is generated and assigned to digital certificates as well as specific files.
Digital certificates allow data to be aggregated and assigned to a single certificate rather than many individual programs. Downloads reported as unsafe by Microsoft Defender SmartScreen can be downloaded by using the following steps: Copy the web address URL of the download or the page that hosts the download link.
Open Internet Explorer 10 or Microsoft Edge on the desktop. Paste the URL into the address bar and hit enter. If the URL was to the page hosting the download, click on the desired download link on that web page. When the file download is complete, it can be launched by right-clicking on the item again and choosing Run anyway. The more you tell us the more we can help. Can you help us improve?
