my OS is Windows XP SP3.

whenever i try to delete these C:\WINDOWS\temp\ Perflib_Perfdata_44c, Perflib_Perfdata_140 DAT file, an error pops up.

and it's like this:

Cannot delete Perflib_Perfdata_44c: It is being used by another person or program.
Close any programs that might be using the file and try again.

and everytime the CPU Usage goes up to 100% in the task manager, it slows down, then poof! it will turn into a blue screen and the message in the blue screen is this:

STOP: c000021a {Fatal System Error}
The windows subsystem system process terminated unexpectedly with a status of 0xc0000005(0x0055001c 0x0054f340)
The system has been shut down.

oh, by the way, the program that i was running that time are Warcraft III, Garena client, Yahoo Messenger 9.

i've tried to full scan using Malwarebytes, Avast, NOD32, Kaspersky(trial version) and yet these things are still here. I've also tried to delete them in Safe mode, but when i restart my PC. it keeps on coming back.

i don't know what else to do anymore. thanks for reading.. :thumbsup:

Hello as I believe this is a system problem and not malware I am moving your topic to th XP forum . They will better assist you with this.

The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe fails. When the Windows NT kernel detects that either of these processes has stopped, it stops the system and raises the STOP 0xC000021A error. This error may have several causes. Among them are the following: Mismatched system files have been installed.
A Service Pack installation has failed.
A backup program that is used to restore a hard disk did not correctly restore files that may have been in use.
An incompatible third-party program has been installed.

Those files you are trying to delete are lock files used by the system when services start up.

No they are not malicious. I have a couple of those files as well. Posted Image

A virus can cause a blue screen of death.

Do you have the above program installed?

FWIW: Whether or not a file is malicious or potentially malicious...is also determined by the path/location of the file.

Those files are there on fresh installs, they are simply file locks for other processes and programs.

Understood and appreciated :thumbsup:.

I just checked my system when you said that you had some...I found none.

I also wanted the OP to realize that filename alone does not indicate whether a file is malicious or not.

This article suggests that the BSOD for STOP: c000021a {Fatal System Error} can be caused by Windows updates: http://www.techsupportforum.com/microsoft-...stem-error.html

Although this is not exactly the same as your error (the status is different), you may want to try uninstalling those updates to see if it helps.
