This sounds like it might be caused by the removal of the wsaupdater.exe.
A piece of spyware replaces the C:\Windows\system32\userinit.exe file with
a file called wsaupdater.exe. It then modifies the registry so that when
you logon the wsaupdater.exe file is executed. After removing the spyware,
(via Adaware, SpyBot S&D, or another spyware detection tool), the
wsaupdater.exe is removed, but the registry still points to it and tries to
execute it during login.

The best procedure to correct this is:

1. Boot into recovery console. More info can be found at
http://support.microsoft.com/default.aspx?scid=KB;EN-US;307654

2. Navigate to the c:\windows\system32 folder and type (without the
quotes) "copy userinit.exe wsaupdater.exe". This will trick the system
into booting by copying the legitimate XP userinit.exe file to the
wsaupdater.exe file and allow the system to boot.

3. Reboot the system and logon.

4. Open regedit (from start->run type regedit)

5. Navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon and modify the value of Userinit to
C:\WINDOWS\system32\userinit.exe

6. Next in Windows Explorer delete the c:\windows\system32\wsaupdater.exe
file.

At this point your system will be stable and allow you to logon
consistently. However, I would recommend following the guidlines in this
article
http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=TROJ_BLAZEFI
ND.A to ensure the system is completely cleaned up.

I've tried this. It doesn't work.

I even tried copying userinit.exe from another source. No
good. I've tried all sorts of combinations of copying,
deleting, and/or renaming those files. It does not work.
Once I've done this and rebooted, I try to login and I see
the desktop background for about 5-10 seconds and it logs
off immediately. I've even tried safe mode.

Any suggestions? I think I could fix this if I knew how to
edit the registry from the recovery console. How about that?

Thanks,
Matt
