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

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

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

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!

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.

Let us know if it works,

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.
PS: I checked on the internet for HDD Diagnostics tool and found this:

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.

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.

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

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.

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

Hello all my laptop recently caught what i believe was called vundo virus, i deleted two .dll's that my anti virus program said were bad. Upon rebooting my computer would get to windows loading screen then give me a blue message which said stop C000021a fatal system error and mentioned something about the logon and it gave me a code 0x00000000 (0x00000000 0x00000000) i brought it to a tech shop and they could not fix it. Although my other two Os's vista and linux will boot my xp pro is having issue's only.I went through vista and used cmd to restore those two dll's from the recycling bin and i rebooterd and got back into xp and no blue screen ! then about 15min later my laptop died(i didnt notice the charger came out).When i plugged it back in and tried to boot xp it again gave me blue message ><.I went back on vista and went online and someone said to replace the winlogon.exe with the on from cd i tried it and still got a blue screen but now with an error code of 0xc000012f 0x0000000 0x00000000.Thank you for reading any help will be greatly appreciated.

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

http://webtoolsandtips.com/remove-trojan/how-to-remove-trojanvundo-uninstall-vundogeng-free/ describes why you cannot boot in any mode without the virus also loading. I am not necessarily recommending you take the link on that site to download the claimed remover. Some of these links can easily download complete trouble themselves.

You first need to create a bootable CD with as much of the removal programs on it as you can find. Now a bootable CD cannot be infected, so at least you will be able to manually delete any of the files listed in the above link. That is a start. Then go to the forum 'security and the Web' on this site and start following the links.

hi

i hope someone might have some useful suggestions to help me with a fatal problem i have just experienced with my acer travelmate 5720 (intel duel core 2ghz running vista sp2) which was running ok when it was switched off. however, when i next tried to boot up, i was met with the bsod with the following message:

STOP: c000021a (fatal system error)

the initial session process or system process terminated unexpectedly with a status of 0x00000000 (0x0000001 0x00100764). the system has been shut down.

i have tried to bootup using safe mode but the system just hangs on the logon.

i have also tried to bootup using the last good configuration but the system fails to finish booting and hangs on the logon.

similarly, i have tried to boot to the c:/ prompt but again the system hangs and fails to complete the boot.

i have not tried to boot with a resue disc or reinstall the os - the hdd contains valuable data that is not backed up and which i cannot really afford to lose.

so, if anyone has so useful help or suggestions, i would be very grateful - please just do not tell me that i should have backed up my data more regularly!!!

many thanks in anticipation of some good advice or suggestions.

A:STOP : c000021a (fatal system error )

Hi Tizza. Im not sure how technical you are but heres what this error means:

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.

Heres a link if a fix is needed: http://support.microsoft.com/default...b;en-us;156669

You said the computer is working ok so I think your probably alright. I feel like a broken record because this is the 3rd time in 3 days I told someone to do this to fix a problem LOL. But its easy and it works. Do a system restore back to a date before this happened
since your able to boot up and your computer is still working. To do this go to start - programs - accessories - system tools - system restore. Select a highlighted date from before you got this message. Select system check point from the right and follow the on screen prompts. Make sure when your computer reboots it says that the system restore was successful and youll be ok my friend. Let me know if you need anymore help or if for some reason this doesnt fix your problem. Take care

Greetings,
I found this thread regarding the error I'm getting on a client's computer:
http://www.techsupportforum.com/f10/...up-516556.html

I did not do all the things he did, but I've managed to clean the hard drive enough to where I briefly reach the desktop (in regular and safe modes) before receiving the exact same error. So, I cannot run any of the preliminary analysis programs on that hard drive unless they work with the infected drive as an external drive--I have an IDE SATA-to-USB adapter (and have backed up my data).

The problem arose after scanning with the free AVG program. I've rescanned the drive with Kaspersky several times and Kas thinks it's clean. I'm not convinced.

Infected computer:
DELL Optiplex GX260
WinXP pro SP3

Computer used to access drive:

The error refers to the fact that the SMSS.EXE service was unable to load for some reason.Since you're not able to boot to Windows you'll have to look to either a repair install or a wipe and reinstall of Windows.For the repair install, read this first if you have IE7 installed: http://support.microsoft.com/?kbid=917964Then use this procedure for the repair install: http://www.michaelstevenstech.com/XPrepairinstall.htm

I doubt it will be the Windows Update that caused the problem, or a lot of people would have been reporting the same problem. It is more likely to be damage caused by the registry cleaner, registry cleaners can often cause more problems than they fix and are not required to keep your system running smoothly, don't use them. That being said I have not known of a registry cleaner to cause such a drastic problem.

Have you tried booting to the Advanced Options using the F8 key and selecting Last Known Good Configuration?

The next morning (I left pc on) I couldn't get anything to run - click on any icon and nothing would happen, CTRL-ALT-DEL and nothing would happen, etc. So I did a hard boot and then it went into the continuous boot loop where it would get to the Windows boot screen with scroll bar and then shut down and reboot again.

Hi there.I seem to be having some serious problems and I have no clue what to do next.Maybe anyone here knows a solution.Yesterday I found out about that latest windows leak, I ran some tests and I was infected with it so I downloaded the patch, installed it and hoped for the best.Because I was working to clean my computer a bit anyway I decided to run ad-aware to scan for any junk on my comp.I have been using ad-aware since like for ever and never had any problems with it.The first time I tried running ad-aware it scanned 7k files and then the problem occured.My windows shut off, I got a bright blue screen wich stated : ***STOP: c000021a (onherstelbare systeemfout}Het systeemproces windows logon process is onverwachts afgebroken, met de status: 0xc0000005 c0x00000000 0x00000000Het systeem is afgeslotenSince I dont know if any dutch people come here I'll try to translate it to english but I might be a little off STOP: c000021a (not repairable sytem error}The system process Windows Logon Process suddenly stopped, with the status: 0xc0000005 c0x00000000 0x00000000The system is shut-down***The only thing possible after this message is hitting your power button and start up your computer again.I tried running ad-aware again and to my surprise it scanned up to 105k files.I thought I was lucky and all went well after reboot but no luck.I got the same error again.After a third reboot I started windows in save mode as I have seen it recommended on several topics at this site.Ad-aware...

A:Stop C000021a (fatal system error)

Hi Dave and Welcome to TSF!

I'm not seeing any similar problems elsewhere, this may be unique to you :(

The suggestion in your thread elsewhere looks incorrect:
Quote:




STOP: c000021a {Fatal System Error}
The Session Manager Initialization system process terminated unexpectedly with a status of 0xC000003a (0x00000000 0x00000000).
The system has shutdown.

Note The status will always be 0xC000003a if you are experiencing the issue described here.




You are describing a oxc0000007b, so the issue isn't as described by MS.

Standard troubleshooting for 0xC000021A:
Quote:




Cause

This error occurs when a user-mode subsystem, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), has been fatally compromised and security can no longer be guaranteed. In response, the operating system switches to kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, this is one of the few cases where the failure of a user-mode service can shut down the system.

Mismatched system files can also cause this error. This can occur if you have restored your hard disk from a backup. Some backup programs might skip restoring system files that they determine are in use.
Resolving the Problem

Running the kernel debugger is not useful in this situation because the actual error occurred in a user-mode process.

Resolving an error in a user-mode device driver, system service, or third-party app... Read more

This is long but stick with me...
The message:
"Stop: c000021a {Fatal System Error} The windows logon process system process terminated unexpectedly with a status of 0xc000000s (0x000000000 0x00000000). The system has been shut down." willappear on the blue screen of death. Sometimes a popup message will appear before quoting "winlogon experienced a problem and must be terminated. Press OK to terminate, press cancel to debug. If I donít push anything my computer will go on running fine. If I press OK, cancel, or the X on the top right, the computer will display another message saying the "memory cannot be read" if I get to this point my computer will undoubtedly fail If I leave the second message be, it will duplicate itself over and over again freezing my computer and eventually displaying the message at the top of this form. If I hit OK or the X it will go to that message at the top anyway. it is usually trigged by logging on from hibernate or stand by after the computer was on hibernate for a long time and suddenly put back on, and turned off to hibernate again. (That last sentence simplified: Computer Hibernation: 2+ hours. Computer turned on: 1- Hours: Computer hibernation or stand by: less than 30 min. on again + Error message displayed in 2-5 min after 3rd use.) Iím not sure I can get more specific from my personal explanation. If anyone understands that, please let me know whats happeing
