Girlfriend infected her laptop with biyebafi.dll virus. Webroot couldn't fully remove it. Tech support specialist told me to run ComboFix in Safe Mode to fully remove the infection. Infection was removed & log was generated, however after restarting, nothing appears after logging in except a blank desktop background.

I tried logging into a different account & same thing is happening there. Restarted in Safe Mode. However, only get a black background w/ Safe Mode written on the corners & the operating system version at the top.

Looked on the internet & found other suggestions to solve this, but none worked. Below are the steps I tried based on these suggestions:

Ctr + Alt + Delete // File -> New Task (run) // explorer.exe // OK (Nothing happened)
--------------------------------------------------------------------------------------
1. Ctrl + Alt + Del to bring up Task Manager.
2. Click "New Task..." then click "Browse..."
3. Click My Computer on the left panel. Click C:\ - WINDOWS
4. Navigate to explorer.exe, right click and copy explorer. Rename it to explorer1 (.exe)
5. Hit Cancel to go back to Create New Task window. Type regedit.exe and click OK.
6. In the registry editor, navigate to the following Key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
7. With the Winlogon key selected, look in the right side window for the
'Shell" value.
8. Double click Shell. In the Value Data box, you should see Explorer.exe. Change it to
explorer1.exe and click OK.
9. Exit the registry editor and reboot the computer

(Nothing happened)
--------------------------------------------------------------------------------------
Delete below from regedit in Windows map:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\explorer.exe

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\iexplorer.exe

(Didn't have either item in the registry)
--------------------------------------------------------------------------------------

Someone in one of the forums suggested that the disappearing icons were caused by "Trojan.vundo" and to run the the Malwarebytes' Anti-Malware application. I downloaded it from a different computer and copied it to the problem laptop via a flash drive. However, the installation displayed several errors during setup. They were as follows:

1. CoCreate Instance failed; code 0x80040154. Class not registered. (This was displayed 3 or 4 times)
2. vbAccelerator SGrid II (or 11; not sure which one) Control. Run-time error '0'.
3. Malwarebytes' Anti-Malware. Run-time error '440' Automation error.

Was able to successfully run VundoFix which came back clean. Webroot guy doesn't think this is virus-related but more a result of the ComboFix, but is at a loss at how to fix this. This is a work laptop, and although we're part of the Administrative group, haven't been able to access System Restore. The laptop's going back to the work IT person tomorrow, but wonder if anyone has any suggestions on how to fix this before it goes to IT. Thanks in advance.

Here's the DDS log:

Thanks for getting back to me. The problem hasn't been resolved yet. The IT person tried connecting remotely to the computer last week at my girlfriend's work but couldn't, so the computer was dropped off yesterday to the IT person.

Although the computer is not currently with us, I was wondering if someone here knew what happened and if there is an easy (or should I say relatively easy) fix to this problem. No new DDS log needs to be posted because nothing was done to the computer since the last log. Would it be helpful if I include the ComboFix log that was generated when the virus was supposedly removed and the disappearing icon problem started?

Hi Tech Info,

Welcome to BC HijackThis forum. I am farbar. I am going to try to answer your question.

The truth is that we might speculate or have an idea about what is gone wrong, but we don't know that for sure without having the information to confirm it.
We don't know how badly the computer was infected, whether it was infected with a file infector, if the system files where patched, if it was a good idea to run ComboFix in Safe Mode (we might do this only in rare case), if it was a good idea to alter the default registry entries, etc.

The best option I can think is to leave it to the IT person to handle the job. If the computer is not fully functional I recommend you to back up the personal data and reformat/reinstall Windows. It might take less time, and it is also safer than trying to pursue the path of removing malware and restoring the damage.

For the future I recommend you not to run ComboFix without the supervision of a trained helper. It is a powerful tool but one should know under what conditions you should run it and what to do if something goes wrong.

I hope your problem get resolved and wish good luck.

Hi farbar. The virus which initially infected the system was biyebafi.dll. Webroot tech support specialist told me that the only way to completely remove it was to use ComboFix. He gave detailed instructions on how to use it (I never would have used it on my own). However, when the disappearing icon problem occurred, what he thought would quickly fix the problem didn't work.

It sounds like the additional information you seek might be contained in the ComboFix log which was generated after it was run. I will attach it to my reply. Even though the computer is currently with the IT department, I was wondering (for my own education) if after taking a quick look at the log, someone might know what caused the disappearing icons and if there is a relatively easy fix for this. This could prove valuable if, god forbid, I come across this problem again in the future.

I can't say if there was an easy way and as I already mentioned ComboFix has a disclaimer and warns the user to never run ComboFix unsupervised.
Above all there is no use to spend time on this and I'm afraid you have to let it go. Many unknown malware get detected sooner or later. The next time it happen your antivirus might detect and remove it. If not you may open a topic and get assistance.
