Malware doctor infection removal and then error c000021a (fatal system error)

Q: Malware doctor infection removal and then error c000021a (fatal system error)

Hi,I have fundamentally the same problem as Laura H from this thread http://www.bleepingcomputer.com/forums/topic342716.html.I've had problems with these fake antivirus programs before and they really did a number on my laptop. I treated the problem using various tools mostly malware bytes and deleting some suspect files.Been working fine for the most part however today out out of nowhere I was attacked by malware doctor. I deleted the suspect file from the temporary internet files folder and ran malware bytes that detected trojan and deleted. Shortly after drwatson ??? was shut down and some time later I think explorer shut down because my desktop went back to basics....no theme,desktop wallpaper etc. the windows 95 look if you grasp what I'm trying to get at. I thought it was no big issue and in my own time restarted laptop when I realized audio wasn't working after trying to play a film.Upon restart I get the blue screen with the same message as Lauras. So for the most part I'm in the same situation as Laura with some minor differences such as I didn't use Spy doctor etc.I have Kaspersky AV installed which has been inefficient in protecting my laptop lately, especially from these fake AV attacks. I am using Windows Firewall which I know is a bad idea.Myrti was helping Laura resolve the issue and I have followed her instructions upto the following actions:'locate this file and right click it > choose rename > rename it to userinit.txtnow we will do the same for explorer.exe and winlogon.exe and hlp.dat and rename the filefind.txt after each search in explorer.txt, winlogon.txt and hpl.txt respectively. ''I will paste the text from these files below. Laura couldn't access her USB in xPUD so Myrti went off on a different direction which I cannot follow. If Myrti could tell me what I need to do after creating the text files it would be of a really great help. Anyone else is also welcome to put in their 2 cents too.Search results for userinit.exe39b1ffb03c2296323832acbae50d2aff /mnt/sda1/WINDOWS/system32/dllcache/userinit.exe24.0K Aug 4 200439b1ffb03c2296323832acbae50d2aff /mnt/sda1/WINDOWS/system32/userinit.exe24.0K Aug 4 2004a93aee1928a9d7ce3e16d24ec7380f89 /mnt/sda1/WINDOWS/SoftwareDistribution/Download/e9500597a78495f397efb821e37bf356/userinit.exe25.5K Apr 14 200839b1ffb03c2296323832acbae50d2aff /mnt/sda1/WINDOWS/ERDNT/cache/userinit.exe24.0K Aug 4 2004Search results for explorer.exed594ea4ac1c0e4675ef2f0063950abef /mnt/sda1/Program Files/Malwarebytes' Anti-Malware/explorer.exe1.0M Jul 23 13:19f2ca5f1467b05dd200373abcb034cb0e /mnt/sda1/WINDOWS/system32/dllcache/explorer.exe1008.0K Aug 4 200412896823fb95bfb3dc9b46bcaedc9923 /mnt/sda1/WINDOWS/SoftwareDistribution/Download/e9500597a78495f397efb821e37bf356/explorer.exe1009.5K Apr 14 2008a0732187050030ae399b241436565e64 /mnt/sda1/WINDOWS/ERDNT/cache/explorer.exe1008.0K Aug 4 2004cc1e71bb2025625c999c1eb3c126bbb5 /mnt/sda1/WINDOWS/explorer.exe1008.0K Aug 4 2004Search results for winlogon.exeaf2bf5320da47fc541c66814b2bb1d1e /mnt/sda1/WINDOWS/system32/dllcache/winlogon.exe490.5K Aug 4 2004ed0ef0a136dec83df69f04118870003e /mnt/sda1/WINDOWS/SoftwareDistribution/Download/e9500597a78495f397efb821e37bf356/winlogon.exe496.0K Apr 14 200801c3346c241652f43aed8e2149881bfe /mnt/sda1/WINDOWS/ERDNT/cache/winlogon.exe490.5K Aug 4 2004Search results for hlp.data4ec5c2e51814d684b2b0a1d8441ced1 /mnt/sda1/Documents and Settings/All Users/Documents/Server/hlp.dat34.9K Aug 4 2004Thank you !!!!Can anyone tell what is wrong with the system from the text files or is it too early to tell yet?Btw I am running Windows XP, not sure about SP, prob 1 maybe 2.To confirm safe mode, last known config and all other options lead to blue screen with error message.EDIT: Posts merged ~BP

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

HelloMy computer has windows XP and got infected with Security Suite and Anti Malware Doctor Protection Centre and after going through the guides to remove them, they were still there. I ran the trial version of Spyware Doctor with Antivirus and it identified something like 15 threats (inc. backdoor.trojan, trojan.bamital, trojan.fakeAV, backdoor.agent.LEL, trojandownloader.agent.OGP, dialer.coulomb_Dialer) and 70 infections so I purchased the full version and ran the scan. Then I removed the threats and rebooted as instructed. When I rebooted, my laptop froze on the blue screen with :STOP: c000021a {Fatal System Error}The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000034 (0x00000000 0x00000000).The system has been shut down.I contacted the Spyware Doctor support but they just told me to contact the laptop manufacturer and do a repair install. I got the laptop second hand and don't have any startup disks. I'm quite a novice with computers so not sure what to do. Also, I have some files that aren't backed up and would like not to lose them.I've tried rebooting in safe mode, safe mode with networking, normal mode, last know good configuration but everything brings up the same screen.Please help!Laura

Originally, she had that annoying XP 2008 virus/spyware, which I think I managed to get rid of with Malwarebytes' Anti Malware and System Mechanic 7. Now I have a new problem. After receiving a recent download from microsoft, upon restarting, I get the blue screen of death with this message;

I can't get anywhere into Windows, I've done F2, F8, F12, everything I could think of without risking more damage since I'm not trained for this. I've booted from the system mechanic CD with the Hard Drive recovery, and while it said it found and fixed a problem, it didn't fix this one. I have no windows CD. The computer is a Dell, and it's running Windows XP service pack 2 with Explorer 6. Heeeeeelp! Other than the F keys, I can't get anywhere with this computer.

Hi everyone,
This morning I turned on my PC (Windows 7 x64) and I get this blue screen error STOP:c000021a [FATAL SYSTEM ERROR].
I can't even get passed the starting windows screen it just keeps on rebooting then getting blue screen again. I've tried safe mode and last known configuration point. Both just give me blue screen after the drivers are loaded. Haven't installed anything new recently so I don't know what the cause of this problem could be. I apparently have no system restore points even though Norton would make them every scan. I can get to command prompt and that is the only thing I can get to. Is there a way I can fix this through command prompt. I think I've attached the screen it gives me and that's all I know.
Thanks!

--What got me to this point:
Troubleshooting a Vista HP machine that had (mywebsearch) MWS and other non-lethal spywares ... and blue screens. Solved the MWS pretty easily with MWB....but the machine kept blue screening (went too fast to write down error codes). OK, so I ran numerous Vista diagnostics .. even removed the HD and ran error checker through another machine with this drive plugged in via SATA to USB adapter. Found and fixed some errors. Also replaced RAM with one of mine, no change in symptoms so I replaced factory ram.
Machine would boot up fine ... but very shortly therafter stop and/or blue screen. One error code I managed to get was relative to some ISATAP thing. I researched this and didn't find too much that was helpful, but I did go to device manager and uninstall this from the network adapter area.

I pulled another SATA 2.5 drive and inserted it into the machine with the intent of formatting and reinstalling OS. As soon as I turned on machine it said no hard drive was found and stopped. I repeated this process with 2 additional SATA 2.5 drives with the exact same error. This really got my head spinning.

I reinserted the orginal drive after downloading all the data to a separate machine and lo and behold, it came right up ... with same errors as noted earlier. So I ran the Vis... Read more

Hello,
Recently I have been getting BSOD's.. got 3rd time in 5 bootups. It happens on Starting Windows screen.
The latest one said something like this:






Quote:
STOP: c000021a {Fatal System Error}
The initial session process or system process terminated unexpectedly with a status of 0x00000000 (0xc0000006 ...... another combination of integers and alphabets which i can't recall)
The system has been shut down.


And this is not it; I have been getting problems lately.
1. This Starting Windows screen stays for long time, so boot time has doubled (or even more)

2. Weeks back, my system went slow overall; I was going to post in here, but before that I ran my Anti-virus, ran defrag tool and these didn't help. Then check disk helped me and everything went like normal.

When my system was slow, opening any drive took very long and was really frustrating. And i was amazed when I used to close the window since it took too much time, and when it was time, that drive was explored in a new window.

Also, I used to play movies, they used to get stuck in between... and that still happened after my system was faster, but it was kinda rare with some movies only.

So now, I am confused about my system. I wonder if both problems are connected to eachother.

I doubt it could be my HDD, though this system is just 1.5 years old.

My desktop computer has completely ceased all function. When I try to boot up, it thinks to itself for a minute, and then flashes the blue screen with this error:

STOP: c000021a {Fatal System Error}
The initial session process or system process terminated unexpectedly with a status of 0x00000000 (0xc0000034 0x00100604).
The system has been shut down.

It does this every single time that I start the computer. I get the option to try and repair, but it just takes 10 minutes longer to reach the same exact result.

I'd like to give a little bit of history to explain the situation better:

The desktop (a Dell XPS 410) began acting fishy about 2 weeks ago, when it began randomly crashing, giving me BSOD's with a variety of errors, including PAGE_FAULT_IN_NONPAGED_AREA and KERNEL_STACK_INPAGE_ERROR. It would always crash within a few hours of rebooting, usually when anti-virus was running, or simply if a lot was going on.

I surfed around for solutions (some here, many in other places), and tried to use the chkdsk /f /r and sfc /scannow programs. Trying to run chkdsk /f /r would nearly finish completing - up until processing the "free clusters" of memory, when it would freeze.

Ever since running the sfc /scannow program, my computer has been in its current predicament. I'm fuming over this, because I've got a lot of files that I'd rather not lose.

Please keep in mind: I cannot get my desktop to boot. PERIOD. Any suggestions as to what could be done will be appreciated.... Read more

Try erasing everything on the hard drive by using a third party program such as DBAN (Link available in my signature).

After DBAN is finished - then try installing XP again.

and its a real *****! So far, attempting to boot to Safe Mode or any other option on the F8 boot menu has no effect. The initialization error occurs before even safe mode is reached, so it becomes an endless loop of splash screen, reboot, splash screen, reboot, rinse and repeat.

The only solution that has yet worked for me is reloading the operating system from the install CD. Fortunately I have built all my systems from scratch with genuine M$ install CDs, not the big OEM house restore disks. Thus, I can use the repair option in the first screen of the retail install and not lose have the routine reset the partition to the original factory load. I am currently on my third reload of the evening and it is 1:30 in the freakin' morning so I am not a happy camper and I am not likely to finish troubleshooting this tonight, but here is what I know so far.

Then it goes to another black screen that list some information on the type of BIOS,copyright information etc then it says Primary hard disk 1 not found strike the F1 key to continue, F2 to run the setup utility. When I strike the F1 key the Windows XP logo comes on like it is going to start and then it goes to a blue screen with the following message.

I called Dell who had me run hardware test from the setup utility which said the system didn't have hardware issues. They had me turn off Primary drive 0 and Primary drive 1 before I ran the tests.

A:Fatal System Error C000021a

One seemingly odd question, is the clock accurate? Computers have a small power supply, a battery or capacitor to keep bios information up to date when computer is turned off. Sometimes this power supply goes bad and has trouble finding hard drive and also resets clock to 12:00 on whatever the earliest date in its program is.

Was wondering if anyone could help me.

I'm running a Rock Xtreme Laptop, 3.4GHz P4, 1024MB RAM, 80GB HDD.

Was running Windows XP Pro, however without reason on one boot It began to load XP, showed the Windows XP boot screen, however once that was finished, instead of displaying the welcome screen as usual, it showed a blank screen (no cursor).

I thought it to be a good idea to re-instal windows, I wasn't bothered about loosing files and folders (I have it all backed up). I tried installing XP Pro, It copied files successfuly after a quick NTFS format, however when it came to installation, I recieved a blue screen with the fatal system error C000021a. Apparently a KnownDLL file failed verification or something.

So I tried reformatting and installing Server 2003 Standard. Again same problem after files were successfully copied.

So... I tried Vista Ultimate, again to no avail. Setup copied files but failed to expand them (install).

Tried each Windows Installation also with full format (not quick), however they hung at 0%!

I presume it's a hard drive error, however need to fix it. Waranty expired Jan 07! !

If ANYONE has ANY IDEAS, please let me know asap. For ease could you please email them straight to [email protected].

Would be GREATLY appreciated. Thank you in advance for any help.

Hello All,

I have just installed a clean install of win xp sp2 on my dell vostro 1500. it worked fine for 2 days, but this morning when i started computer , it starts and as soon as i c my desktop, i get a blue screen saying this message:

"c000021a fatal system error, the windows subsytem process terminated unexpectedly - 0x7c9101b3 0x0069f28c"

the dumping process started ... and it does that restarts and does the same again.

can some one please help me out.

Thanks i appreciate it.

A:C000021a fatal system error in WIN XP pro sp2

Worth a look: http://support.microsoft.com/kb/112455, technical info follows:0xC000021A: STATUS_SYSTEM_PROCESS_TERMINATEDThis occurs when Windows switches into kernel mode and a user-mode subsystem, such as Winlogon or the Client Server Runtime Subsystem (CSRSS), is compromised. Security can no longer be guaranteed. Because Win XP can?t run without Winlogon or CSRSS, this is one of the few situations where the failure of a user-mode service can cause the system to stop responding. This Stop message also can occur as a result of malware infestation or when the computer is restarted after a system administrator has modified permissions so that the SYSTEM account no longer has adequate permissions to access system files and folders.If the reason for the reinstall was malware...I would say that odds are that you are still infected. My suggestion would be to ask to have this thread moved to the Am I Infected forum. The problem with that is that you don't seem to be able to boot into Windows to do anything useful.If you are sure...not just wishful...that it's not a malware situation, then I would suggest a repair install of XP.Could also be some type of hardware problem, but that's just enumeration of the logical suspects possible. You haven't posted sufficient information for anyone to make that call, IMO.Louis

Hi,
 
The other day we found a computer giving this error and continuosly resetting:
STOP: c000021a {Fatal System Error}
 The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000135 (0x00000000 0x0000000)
The system has been shutdown
 
We reviewed kb156669 and it says some causes:
•Mismatched system files have been installed:  "No as far as we know"
•A Service Pack installation has failed:  "No as far as we know"
•A backup program that is used to restore a hard disk did not correctly restore files that may have been in use:  "No as far as we know"
•An incompatible third-party program has been installed: "No as far as we know"
 
We resolved the problem copying the folder system32 from a new computer to the old but the question is if someone know how to troubleshoot this and to know exactly the cause.
 
Thanks in advance.

A:STOP: c000021a {Fatal System Error}

The previous person that used it might have added dual boot with linux and edited the .Ini boot file.

 

You understand that the system32 folder contains a folder called drivers, which contains the drivers related to the software installed on the operating system?
 
So basically copying the system32 folder from another pc, and expecting all software to run fine is not going to work out well for you.
For example, here i have 2 pcs, pc A and pc B.
.
Pc A has avast and malwarebytes software installed.  Pc B has Microsoft security essentials and SuperAntiSpyware installed.  How could i expect the system32 folder from pc A, to have the correct drivers for pc B?

I have been having problems recently with my laptop... The hard drive tends to stop functioning and then crash. When I tried to reboot, it said the operating system was not found. So I decided to give the hard drive and the laptop a break to cool down, and it worked great for a while, then crashed again. And then it asked me to start the windows repair, and when I did it got a stop error, asking bs to disable shadowing on the BIOS. But I dont know how to disable it so I end up restating after waiting a bit. I tried using safe mode but the boot up kept getting stuck at crcdisc.sys, and then later when I tried to use system repair I got this error:

STOP: c000021a {Fatal Systrm Error}

Hi all:

I'm looking for any suggestions for a system error message I've just started getting. When I try to start my pc I get as far as the Windows logon screen and then it hangs with this message:

Stop: c000021a {Fatal System Error} The windows logon process system process terminated unexpectedly with a status of 0xc0000005 (0x00000000 0x00000000).
The system has been shut down.

I tried to get into safe mode and also tried "Use last known good configuration" without success. Is this a software or hardware issue and can I try anything before reloading the operating system? If I have to try to reload will I lose everything on the drive?

This is an older pc - Compaq Presario (approx 7 years old), running WindowsXP Home, sp2 and had all available updates. I haven't added or removed any software recently. The only thing unusual in the recent past was a power outage two days ago, but it was running fine yesterday. Today I played World of Warcraft for a short time then downloaded updates for SuperAntiSpyware and Adaware, shut the pc down and when I tried to turn it on, started getting this message.

I would appreciate any suggestions anyone might have. If it comes to an operating system reload, I'd be grateful for any suggestions for saving existing data on the drive.

Thanks in advance.

Here is a couple of things that you can try. First when you start you computer, hit f8, then when the screen comes up choose to start from the "last configuration that worked". Then see if you are still getting the error.

If that doesn't work then you will have to pop your install disk into your computer and do a repair. This will do exactly what it says, it will repair your xp partition.

Try both of those things and see if either of them help.

I have windows xp media center edition. The stop c000021a fatal sytem error message with a blue screen keeps coming up. The computer will not allow me to get to the start up menu. When first attempting to correct the problem I was able to get into Safe Boot Options Menu but still could not run Safe Mode, Last Known Good Configuration, or Start Windows Normally. When I turn on the computer now and press F8 it makes a loud beep noise for as long as I hold it down then goes back to the blue screen. Please Help!

If you have the Windows XP CD you can do what's called a repair install which will re-install Windows without disturbing your files. Before doing that I would use something like Symantec Ghost or a linux live CD to get access to your important files.

You could also try to download and burn one of the virus scanning CD's available from avira, bitdefender, AVG, etc and see if you can remove the infection and if that fixes the issue without doing anything else.

After you get access to your files, learn to do proper backups. Having important files in a single location is just asking for trouble.
