CPU usage is all occupied, how to deal with it?

When using a computer, we usually encounter a lot of problems, such as a sudden very large card in Windows, and even a very high CPU usage in the resource manager, reaching 100%. Under normal circumstances, the solution to this problem is to restart, press F8 to enter the recovery mode to kill the virus, remove the virus and then return to normal. However, the problem of 100% CPU usage is not necessarily caused by a virus. The following small series will be based on the CPU occupancy rate of 100%, a brief analysis and solution:
computer CPU accounted for 100% how to solve?
1. The driver is not certified, resulting in CPU resources occupied 100%. A large number of beta drivers flooded the Internet, causing hard-to-find failures.
2. Anti-virus and anti-virus software cause malfunction. Because some anti-virus and anti-virus software have added random monitoring of web pages, plug-ins and emails, the system burden is undoubtedly increased, and services can be selectively opened according to the situation.
3. Virus, Trojan caused. A large number of worms are rapidly replicated inside the system, resulting in a high CPU utilization rate. Solution: Use the latest anti-virus software to perform anti-virus in DOS mode. Regularly update and upgrade anti-virus software and firewalls, strengthen anti-virus awareness, and master the correct anti-virus knowledge. (The kid is the situation encountered.)
4. Excessive startup items cause CPU congestion. Simply start the ——run——msconfig—— startup to turn off unnecessary startup items and restart.
5. View “Svchost.exe” process.
What is the Svchost process? Svchost.exe is a core process of the Windows XP system. Svchost.exe does not only appear in Windows XP, but Svchost.exe exists in Windows systems that use the NT kernel. Generally, the number of Svchost.exe processes in Windows 2000 is two, and the number of Svchost.exe processes in Windows XP has risen to four or more.
How can I identify which Svchost.exe process is normal and which are virus processes?
The key value of Svchost.exe is in HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsNTCurrentVersionSvchost", each key value represents a separate Svchost.exe group . So how do you tell if Svchost.exe is a virus? If you find the Svchost.exe program in another directory, it is probably poisoned. Another way to confirm that Svchost.exe is poisoned is to view the execution path of the process in Task Manager. However, since the task manager that comes with the Windows system cannot view the process path, a third-party process viewing tool is used.
6. Reinstall the system. If this problem does not occur, then slowly install the required software to determine whether the CPU will be fully loaded. If it is fully loaded, it may be caused by software incompatibility.
The above are just some simple analysis and solutions. In practice, you need to make a difference. I hope that the methods provided by Xiaobian can give you some help.
