I am at the end of my rope. I have been fighting an infected Windows 2000 SP4 computer for a couple of days now. I think I cleared most of the infected files and registry entries. However, two files keep coming back. One file is a.exe, which usually announces itself with the following pop-up: a.exe - Application Error : The exception Illegal Instruction
An attempt was made to execute an illegal instruction.
(0xc000001d) occurred in the application at location 0x00401f6e.
Click on OK to terminate the program
Click on CANCEL to debug the program

If I click OK, the message goes away and I can normally go into the C:\WINNT\system32 folder, find it and delete it. The other file that keeps coming back is ban[1].exe. This file can always be found in the C:\WINNT\Temporary Internet Files\Content.IE5 folder. I have run scans with Malwarebytes and SuperAntispyware in normal mode and safe mode. If I haven't deleted the files, both scans find the files and delete them. If I have deleted the files, neither scan finds anything else. I have also run a scan using Spybot Search and Destroy and that hasn't found anything either. I'm not really sure where else to look. Any help would be greatly appreciated.

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

==>PLEASE DO NOT NOW POST LOGS<== unless a log is specifically requested.
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.

One more please


Vista users can refer to these instructions to open a command prompt.

Alternatively you can do this:

Please download peek.bat and save it to your Desktop. Double-click on peek.bat to run it. A black Command Prompt window will appear indicating the program is running. Once it is finished, copy and paste the entire contents of the Log.txt file it creates in your next reply.

If you encounter a problem downloading or getting peek.bat to run, go to Posted Image > Run..., and in the open box, type: Notepad
  • Click OK.
  • Copy and paste everything in the code box below into the Untitled - Notepad.
@ECHO OFF
DIR /a/s C:\WINDOWS\scecli.dll C:\WINDOWS\netlogon.dll C:\WINDOWS\eventlog.dll C:\Windows\cngaudit.dll >Log.txt
START Log.txt
DEL %0
  • Go to File > Save As, click the drop-down box to change the Save As Type to *All Files and save it as "peek.bat" on your desktop.
  • Double-click peek.bat to run the script.
  • A window will open and close quickly, this is normal.
  • A file called log.txt should be created on your Desktop.
  • Open that file and copy/paste the contents in your next reply.
-- Vista users, users can refer to these instructions to Run a Batch File as an Administrator.

Using the first 2 logs you have, please follow these directions


Now that you were successful in creating those two logs you need to post them in our HJT forum There they will help you with the removal through some custom scripts and programs that we cannot run here in this forum

First, try to run a DDS / HJT log as outlined in our preparation guide:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/

If it won't run, don't worry, just give a brief description and tell them that these logs were all you could get to run successfully

Post them here:
http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

The HJT team is extremely busy, so be patient and good luck

Please close this topic as the issue has been resolved. Downloading and installing every last Windows 2000 SP4 Microsoft update did the trick. Thanks again for all of your help.
