Win8 system filter to prevent programs from running

There has been a breakthrough in many features of WINDOWS8, and today we're going to talk about SmartScreen filters. SmartScreen filter is an original IE to help detect phishing site functions, is IE8 and IE9 of the self-contained function. In Windows8, this functionality is integrated into the operating system.

SmartScreen is a security protection software that can prevent malicious programs from running in WINDOWS8. But it occasionally blocks legitimate applications, and SmartScreen sends that information to Microsoft, so it can also involve some privacy issues.

The working principle of SmartScreen

By default, the WINDOWS8 system sends all the information you download and install to the Microsoft server. The Microsoft server will return the evaluation of the application-if you download the application is legitimate and more commonly used applications, such as Firefox or ITUNES,WINDOWS8 will automatically run the application.

If SmartScreen does not have information about the application, whether it is a new malicious plug-in or a niche software, WINDOWS8 will organize the program's operation. It also automatically blocks known malicious software from running.

In IE8 and IE9, the principle of smartscreen works as well. When you download an application, the SmartScreen filter for IE will send the relevant information to the Microsoft server, and then the Microsoft server can then decide whether to download the application.

In Windows8, this function has been integrated into the system. Even if you use other browsers (Flash browsers, Google browsers, Firefox, and so on), SmartScreen can also detect applications.

When you run an unknown program

When you try to load an SmartScreen application, it automatically pops up a message "Protecting your system" to prevent the program from running. When you see this message, you will naturally be alert to determine if the program is safe. Occasionally, however, legitimate applications are blocked.

Solution:

If you are sure that the open application is safe, click "More Info".

Then click the "Still Run" button and the system will allow the program to run.

About privacy issues.

Because SmartScreen will send every piece of your program information to the Microsoft server to see if the program is allowed to run. Therefore, the media pointed out that this is a possible violation of privacy issues.

SmartScreen will send a small amount of data from the program to the Microsoft server when you run the program. This information includes the name of the file and a small amount of program content, of course, compared to the Microsoft server database. If the application meets safety standards, it can be run smoothly.

As soon as you try to run an application under Windows8, Microsoft learns the name of the file and your IP address.

Microsoft also issued a statement in the government saying they did not want to create a database of users running those applications, as follows:

We can confirm that Microsoft is not to establish a User IP address and User program usage database. Obtaining an IP address is necessary to link to a Microsoft server, but we will periodically delete the relevant information, and we will take steps in the background to protect the user's privacy. We do not use this data to contact users or send ads, and we do not disclose this data to third parties.

We can be sure that SmartScreen is a very effective security protection function, he can help those who are not aware of malicious programs to prevent the violation, whether to use or depending on the individual situation to determine.
