Perflib_Perfdataxxx.dat（perflib_perfdata_238.dat ）文件是怎么产生的

问：
最近木马清道夫总是提示c:/winnt/system32下新建了 perflib_perfdata_238.dat 文件夹，或者是perflib_perfdata_*.dat     *是其他数字。 但我去system32下找确找不到这个文件夹。
 
答：
perflib_perfdata××××.dat这个文件中的xxx是随机的数字，只有在系统非正常关机的时候，比如没有开始——>关机，而是直接按关机按钮关机，
需要注意的是，在系统正在进行一些操作的时候关机，比如正在搜索一个文件，。。
系统没办法自动清除这些文件，只有手动写批处理，加载开机运行脚本清除。

SUMMARY

Files with the name Perflib_Perfdataxxx.dat may accumulate under the %SystemRoot%/System32 folder, where xxx is a random number.

MORE INFORMATION

These files are generated by processes in the normal course of operation; however, files are orphaned when you do not shut down a computer properly, such as by pressing the power button on a computer.

Note: It is also possible that these files can be orphaned while a server is running. Microsoft is researching this problem and will post more information in this article when the information becomes available.

To delete the orphaned files, you can use an automated logon script.
