The reason why CPU resource occupies 100% under Win7

1, the driver has not been certified, resulting in 100% of CPU resources. A large number of beta drivers are flooding the web, causing difficult to find fault causes.

2, anti-virus software cause failure. As a result of some anti-virus and anti-virus software added to the Web page, plug-ins, mail random monitoring, undoubtedly increased the system burden, can be selected according to the circumstances of the open service.

3, virus, Trojan caused. A large number of worms are rapidly replicating within the system, resulting in high CPU utilization. Solution: Use the latest anti-virus software in DOS mode for antivirus. Update anti-virus software and firewalls regularly, strengthen anti-virus awareness, master the correct anti-virus knowledge.

4, start-> run->msconfig-> start, turn off unnecessary startup items, restart.

5, view the "Svchost" process.

Svchost.exe is a core process of Windows XP systems. Svchost.exe not only appears in Windows XP, but there are Svchost.exe in Windows systems that use the NT kernel. Typically, the number of Svchost.exe processes in Windows 2000 is 2, and the number of Svchost.exe processes in Windows XP rises to 4 and more than 4.

How can you tell which are the normal Svchost.exe processes and which are the virus processes?

The Svchost.exe key value is in "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Ntcurrentversionsvchost", and each key value represents a separate Svchost.exe group.

Microsoft also provides us with a way to see how the system is running services in the Svchost.exe list. For example, in Windows XP: In Run, enter: cmd, and then enter in the command line mode: Tasklist/svc. The system lists the list of services. If you are using a Windows 2000 system, replace the previous "tasklist/svc" command with the following: "Tlist-s".

If you suspect that your computer may be infected with a virus, Svchost.exe services can find anomalies by searching for Svchost.exe files. In general, you will find only one Svchost.exe program in the "C:windowssystem32" directory. If you find a Svchost.exe program in another directory, it is likely to be poisoned.

Another way to confirm that Svchost.exe is poisoned is to see the execution path of the process in the Task Manager. However, because the task Manager on the Windows system is not able to view the process path, you use a Third-party Process viewer tool.

The above briefly describes the Svchost.exe process of the relevant situation. In short, Svchost.exe is a core process of a system, not a virus process. However, because of the particularity of the Svchost.exe process, the virus will do everything possible to invade Svchost.exe. You can confirm whether poisoning is possible by looking at the execution path of the Svchost.exe process.

6, view the network connection. Mainly is the network card.

7, the network card, video card, sound card Uninstall, and then install the driver again.

8, reload system, commonly used software, of course, to install the driver, take a few days to see. If this problem does not occur, then install other software, but it is best to install a software, first in a few days. If there is no problem, go ahead and install.
