Recently, someone asked for help. There are two system processes in the computer, one is system and the other is system Exe, let me briefly introduce the difference between the two for you. You are welcome to refer to and learn.
What does system mean? Simply put, it means computer system!
There is a system process in the system, but note that it is not system exe。
system. Exe is a file generated by netcontroller trojan virus, which appears in C: \ windows directory. It is recommended to delete it. But it should be distinguished from the system process of the system. The system process is not Exe.
Every time you start up, you have to start up. This has nothing to do with the slow running of your computer. If the computer is slow, you can restore it and reinstall it before you can clean up the garbage~
System is a Windows page memory management process with level 0 priority. The system cannot start without it.
And the system under windows Exe (note! There is. Exe after it) process is a Trojan virus. To delete
system. Exe process analysis: gaobot.exe AO、netcontroller、Trojan/PSW. WyHunt、Worm_ Bbeagle. K, grey pigeon and other Trojan viruses also generate the file, which basically belong to the backdoor worm Trojan, which is used by malicious attackers for remote control. The virus modifies the registry, creates a system service system, realizes self startup, and puts the virus module systemkey DLL，system_ HOOk. The DLL injection process runs, and the virus module can record keyboard actions, steal account and password, and allow malicious attackers to remotely control the computer.
If you use XP system, this process cannot be ended in the "task manager". The ended process indicates that this process cannot cause direct harm to the system. However, it may be forced to end with other software, but this will cause blue screen and other phenomena.
If you are a vista system, the blue screen will be displayed immediately after you finish. This is the process of the system, which runs in memory! If you turn it off, there may be two situations!
1： Blue screen.
2： The dialog box that says you are an illegal program appears.
In general, the system may crash!
System is a normal process of the system. It is usually non-toxic and belongs to system permission. There is also a system file without extension in the system, which is the system registry file. The location is:% systemroot% \ system32 \ config \ system
How to manually check and kill system Exe virus
1. Abort all systems with task manager Exe process;
2. Run CMD and type del / F / a% d% in the DOS window: \ recycler \ system exe del /f /a %d%:\system. exe
Delete autorun.com under the root directory on all hard drives Inf and system Exe and system in the recycle bin Exe file;
3. Delete the key icon under "start / program / start";
4. Run regedit to find and delete all system Exe, and then restart the computer.
The problem of 100% CPU utilization of system process is finally solved ~
Since I brought the computer back to the dormitory more than half a year ago, I have been troubled by a problem:
From time to time, the system process will cause 100% CPU utilization. And no matter how to reinstall the system, no matter which version of the system (I have changed three systems successively), there is this problem. There are various reasons for the 100% occupation of CPU in online search, but there is no trace of system.
Therefore, I began to worry about the hardware problem, because the whole computer is my own DIY. I bought only parts and installed it by myself. At this time, in order to play a release version of the game, the CD-ROM drive was removed, and then the system process has been honest for a long time (it turns out that this was because it was the coldest time in Beijing, so... See below for details). Naturally, I thought it was the conflict between the optical drive and other devices that caused the abnormal CPU occupation of the system process.
It's not a long time. One day, in order to pass civilization 3 to someone, I hung up the CD-ROM drive - how can you say it's such a coincidence? After the CD-ROM drive was hung up, I noticed that the CPU utilization of the system process soared again; It's a pity that it's not high after the optical drive is removed. At that time, I was helpless, so I had to give up temporarily and leave it to be solved later.
Then we have to talk about last night. The work is hot, and suddenly the reaction speed of the system drops sharply, which has reached the point where I can't bear it. Open the console. Sure enough, the system process soared to 100%. Extremely unhappy, NND, when not to come, this time to find fault. Copy the guy! When unpacking, it was suspected that the temperature of some equipment was too high, so the finger temperature measurement - well, well, it was actually dangerous. If it caused electrostatic breakdown... And it was turned on at that time... - the temperature of the main chip radiator was normal.
The problem remains. When I went online again, it was strange that after turning a few pages, I found several cases: most of them were caused by using a certain software, and the CPU of the system process occupied 100%, so I ignored them; Finally, there is an example that attracted my attention. It is probably a CPU overwork caused by too high temperature of PFM. PFM, er, forgot its full name, refers to several three-phase power supply devices around the CPU. Well, then, when the situation appeared, Lima unpacked, as expected - once unpacked, the CPU utilization rate of Lima decreased and returned to the normal level... Tnnd... Computers should be open these days!? Looking back on my previous experience, I happened to meet the quiet days when I removed my CD-ROM drive, probably because when it was the coldest in Beijing, although the dormitory had heating, I usually opened the window or opened the door for ventilation, so the temperature of the dormitory was lower than now, and the temperature of the computer working environment was naturally slightly lower. The system process causes the CPU utilization rate to be 100%. 1. The heat dissipation glue of the computer CPU falls off
As a result, the temperature of CPU is overheated and cannot be compatible with multiple hardware at the same time
My solution: remove the temporarily useless hardware
Or remove the fan of the CPU and apply a layer of heat dissipation glue on the surface of the CPU
2. The compatibility of the motherboard with the network card is not very high
The best way is to change a motherboard
Otherwise, it is to adjust the compatibility of the host on the BIOS
3. There is a lot of dust on the hardware
Generally slot or network card
Cause problems in the process of data transmission
Let the computer spend a lot of resources to solve it
And it can't be solved
So the system process takes up a lot of CPU
The South Bridge is broken and the progress is 100%
In the virtual machine, the problem that the system process occupies 100% of CPU is solved
Recently, VPC 2004 was used to configure a virtual environment of office 2007 + SharePoint Portal Server 2007 + VS.NET 2005 + VSTO 2005 se. After hard starting the virtual Windows 2003, it was found that the machine speed was seriously slow. It took a few minutes to open any window! Call out the task manager and see that the CPU is occupied by the system process.
Solution process: since the virtual machine does not use the network, eliminate viruses and vulnerability attacks. The virtual machine has a shared folder to a partition of the host (WinXP SP2). Is this the problem? Cancel the shared folder after shutdown, and solve the problem after restart. But I'm not willing. There's no problem with the partition of the host. The shared folder has been used many times, and such a problem has never happened? Due to the cancellation of shared folder, I can't install VS.NET 2005 in the format of video disc, so I virtualized again. Suddenly I thought whether it was the problem of virtual Deamon tool? So mount image to the shared folder, and then hard start, and the problem reappears.
