What if the CISVC. EXE process occupies too many system resources?

Q: I have been using Windows XP for more than half a year. It has been quite stable and I have not installed any software that affects the system performance. But recently, I suddenly found that the system often becomes very slow, press Ctrl + Alt + Del to open "Windows

After the Task Manager crashes, A cisvc.exe process is found in the Progress logging card, occupying a lot of memory resources and CPU time. After the process is terminated, the system will return to normal. Is this normal? How can I manually scan and kill a trojan?

A: If you change the name of the virus to cisvc.exe, the cause of system slowdown is that the Indexing Service in the system is enabled. When the system is idle, the indexing service reads a large amount of data from the files on the hard disk, therefore, it is generally not recommended to enable this service except for systems with special purposes (such as large-scale data access. If yes, run services. msc opens the Service management interface, finds "Indexing Service", double-click it, click "stop", and change "Startup Type" to "disabled" (see figure ).
