Win8 system open the folder to the cause of suspended animation

First, open the folder full of programs, just scroll to a place, the system is abnormal after the stop, the highest ranking is called MsMpEng The program, while the program inside the folder only shows the icon, and the rest are white icons. After the currently displayed program icons are displayed, the system returns to normal and the program is restored to a low occupancy rate.

Second, right click on it and open its file location in the %PROGRAMFILES%/Windows Defender folder. It can be seen that the file is a file of Windows Defender, and the corresponding service is WinDefend service. At this point, you can probably guess the cause of the suspended animation: open the folder full of applications, according to the default rules, the executable is the primary check object containing threats such as viruses, although the program is not open, but the program icon is to be accessed The program body, so also check; and too many files, only one queue check, pass (release the icon). It takes time to check itself, plus the need to check for so many programs at the same time, so the system is stuck.

After we find the reason, the solution is not difficult to think of:

a. If other protection software is installed, Windows Defender should close itself. If it is not closed, enter the service. Just turn off the service.

b. If no other protection software is installed, Windows will use Defender as a basic protection by default, so you need to set a special case.

This problem occurs here, but it is rarely encountered in previous versions of Windows. The main reason is that Windows 8 has its own Windows Defender enabled by default. The previous version requires manual installation. use.

Setting some files or folders to something other than checking is also very simple: press the start button, return to the start screen and type Defender to find the Windows Defender application, click the Settings tab, on the left There are corresponding exception settings on the side. Some files can be set, with the exception of the folder; you can also set a type or process that is not checked. Of course, the exception is that you need to know that the programs you have are harmless.

After adding the exception, opening the folder again will not be the case, you need to explain again, the program inside the folder needs to be responsible for security. After testing, the scan results are only valid for this launch without adding an exception. That is to say, there is no such problem after entering the folder once, but the situation will repeat after the restart. The reason is also very simple: the system can't guarantee that the file has not been modified during the restart. After the boot, the changed program may have been stored in this place, and it is natural to check it again.
