Blue Screen - c99921a

I recently got hit with the Brave Sentry malware and ended up shutting down
my PC by powering off. Now when I power up I get a blue screen with the
following message:

C00021a
The Window Login Process system process terminated unexpectedly with a
status of 0x80000007. The system has been shutdown.

I tried restoring to Last Known Good Configuration and also running in Safe
Mode, but each time I end up with the same error.

What can I try next?

Welcome to MajorGeeks.com, please follow our standard cleaning procedures:

http://www.majorgeeks.com/images/grenade.gif Run ALL the steps in this Sticky thread READ & RUN ME FIRST Before Asking for Support

• Make sure you check version numbers and get all updates.

http://www.majorgeeks.com/images/grenade.gif Very Important: Make sure you tell us the results from running the tutorial...was anything found? Were you unable to complete any of the scans?...Were you unable to download any of the tools?...Did you do the on-line scans as suggested? etc.

http://www.majorgeeks.com/images/grenade.gifAfter doing ALL of the above and you still have a problem, make sure you have booted to normal mode and run the steps in the below thread to properly use HijackThis and attach the log:

http://www.majorgeeks.com/images/grenade.gif Downloading, Installing, and Running HijackThis

• Make sure you also rename HijackThis.exe as suggested in the procedures. Use analyse.exe for the new name. This is very important due to some new infections going around..

http://www.majorgeeks.com/images/grenade.gif In your next post, please make sure you attach the following logs and that you have run these scans in the following order:

• CounterSpy - ONLY IF you were not able to run Windows Defender
• Bitdefender - from step 6
• Panda Scan - from step 6
• runkeys.txt - the log from GetRunKey.bat
• newfiles.txt - the log from ShowNew.bat
• HijackThis

NOTE: You can only attach 3 files in a single message so it will require that you use two messages to attach all of these logs!

 

Thanks for the tips.

It seems like all of the tips I've received assume that I can get past the Windows startup, which at the moment I can't because of the Windows Logon Process error, even in Safe Mode. Am I missing something?

Note: The o/s is Windows XP SP1; I won't be able to run Microsoft Windows Defender.

If you can't get into Windows I would post in the Software Forum to get this resolved first. Once you're able to get into Windows come back and we will finish the cleaning.
