NT Kernel & System Process CPU High-occupancy problem solving method

Recently, the computer suddenly appeared in the phenomenon of Dayton, view process management, found that a system process has been taking up CPU 50%, and the boot.

I've searched a lot of information on the Internet for this problem. Most of them said the system should be cleaned up or balabala such as computer white solution, are copied paste, see the Foreigner wrote an article on NT Kernel & System Process CPU Excessive problem analysis, I think the analysis is very good , but unfortunately I finally found that my problem does not appear in the driver above (has been in this misunderstanding for a long time, the driver installed the unloading, tossing and leaving).

Well, the background to the introduction here, the following is my question is how to solve:

First Open process Explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) to view the system process.

Next, double-click the system process, go to the properties, see threads,

By CPU sort you will find out what the backend services occupy so high CPU, I later discovered unexpectedly is 91 Assistant (connect the Android and PC software), although uninstall 91 assistant, but it unexpectedly in C: Windowssystem32drivers left under the 91ass**.sys a file, every incoming system will load, directly caused my CPU occupancy rate is high, dual-core CPU almost waste a core.

In this seriously despise 91 assistants this software, almost let me reload the system!! Finally, I would like to thank the lab P-God, help a lot ~
