Hello,

Two days ago I logged onto my computer and received a security alert
asking me to update my computer, I can't remember what it exactely
said, but it appeared to be a Microsoft security update. I believe
this was a virus. After I updated this, the computer restarted but
there were no icons, no task bar, the screen was just the desktop
picture. So I managed to use the Task Manager to bring up an Exployer
page and downloaded Super Anti Spyware and ran a scan. Right when the
virus was found, there were several trojans that were found, one of
which is SVCHOST.exe, the computer would just restart. It did this
every single time. I managed to download a antimalware scan
application and that found the same viruses and removed everything. I
thought everything was ok at this point. Then I was trying to do some
clean up on the desktop and remove an old Norton Antivirus software
from the Add/Remove option in the control panel. This caused the
computer to terminate, and all I received was the blue screen saying
"Stop C000021a Fatal System Error The windows logon process system
process terminated unexpectedly with a status of OxC00000005 The
system has been shut down" I restarted the system and pressed F8 to
start up windows at the last good configuration. But after I select
this, it askes what my administrative password is. I don't have one,
and when I hit return, that is wrong. How can I get by this? I am
not with the computer right now, so I mentioned everything I
remember. I do not have the Windows cd either, so I can't try to
reinstall the OS. Is there a solution without that cd?
Thanks

Erin

I'm sorry but there is no solution without installation media because it
really sounds like a clean install is required. If this is an OEM machine
(HP, Dell, etc.) and the recovery partition is damaged or you forgot to
create recovery disks, call the OEM and purchase a set. These recovery disk
sets are usually very inexpensive, around $20.

If this is a generic-built machine, you will have the COA sticker on the
side, back, or bottom (if a laptop) of the computer. XP can then be
installed using a generic OEM install disk and that COA Product Key. If you
had a retail copy of XP and have lost it:

How to Replace Lost, Broken, or Missing Microsoft Software or Hardware -
http://support.microsoft.com/default.aspx?...KB;en-us;326246

Of course, a qualified computer tech who can see the computer may be able to
get around the login issues but it really does sound to me like the OS is
fatally corrupted. In every case where I've had a client's machine with
your error a clean install has been required. If you decide to try a
computer tech, I don't recommend using one from a
BigComputerStore/GeekSquad type of place.

0xC000021A: STATUS_SYSTEM_PROCESS_TERMINATED
This 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

Unless you have GoBack installed and you are using XP then see the following. If not
then follow the advice given to you by Malke
