For the first time in my experiences with cleaning computers, I need your help!

I've fixed like 30 computers of these rogue applications with a success rate of 100% until today. My sister's computer has one that simply will not go.

Specs:
Windows XP Pro (which is apparently the only OS this rogue application lingers in)
Antivirus: Symantec Antivirus Corporate Gold Version
Firewall: Sygate Personal Firewall Pro

I've seriously tried about 15 things already that have all worked in the past. To list the main ones:

1. Full scanned with Malwarebytes, Spyware Doctor, Spybot Search and Destroy, and SUPERAntiSpyware both in safe mode (administrator account) AND in normal startup mode.
2. Ran Rkill.exe and did all above. The process seems to be hidden, (maybe a rootkit?) because the the trojan titled ekr.exe is starting on startup without being listed in the msconfig and even if we end the process, the rogue application is still there. This leads me to believe ekr.exe is the trojan that turns everything else on and is useless after it does so.
3. Unchecked all fishy items in msconfig's startup tab
4. Searched the registry in specific locations for the string ekr and ekr.exe and manually searched other directories where reported threats were, but was not able to locate anything in specific. The name must be randomized, (as it is for many of the computers I have fixed). Searched the computer for ekr.exe and found nothing except for in the prefetch folder (come to think of it, I will have to redo this step as I am not sure if search in system files and folders was checked), and I deleted that file in the prefetch folder for fun but still it hasn't done anything.
5. Ran a registry .reg fix that did nothing after reboot
6. For fun found the key to unlock the rogue application to see what it would say and do, and it obviously hasn't done anything. (provided in screenshots below)
Many more things, but all unsuccessful.

Unlocking the program for fun (and to give you a glimpse of it):

My next plan of action is to post a hijackthis log to the log forum on here, but I have never needed to use this tool in the past but would appreciate any good advice. I also plan to run Rootkit revealer with my antivirus turned on in hopes that the system realtime protection will catch the found possible rootkits.

Please take this thread serious, thank you!

Hello, looks to me as if possbly an EKR frojan is trying to connect yo the internet thru your Steam application.

ESET should get this.
Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer,Opera or Firefox to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.


The ERROR loading cshude dll in your first image can be fixed.
A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.

Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
Open the folder and double-click on autoruns.exe to launch it.
Please be patient as it scans and populates the entries.
When done scanning, it will say Ready at the bottom.
Scroll through the list and look for a startup entry related to the file(s) in the error message.
Right-click on the entry and choose delete.
Reboot your computer and see if the startup error returns.
