Let's try one more thing and then I'm going to have to go check with some experts on how to proceed.


Please download and install the program Registry Lite from here:

http://www.resplendence.com/reglite

Once it is installed, please double click on the icon that should now be on your desktop. If an icon is not there, then check under programs portion of the Start Menu.

Once it is opened, copy and paste the below line, into the address field of Registrar Lite.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\\AppInit_DLLs

And press enter. You will now be presented with new information in the bottom right and left sections and on the right section, the name AppInit_DLLs should be highlighted. Double-click on the AppInit_DLLs entry and copy and paste the text found in the value field in your next reply to this post.


Also post a new hijackthis log.

I'd also like to see this report. It may give us a better look at things.

Please download Rootkit Revealer (link is at the very bottom of the page)
  • Unzip it to your desktop.
  • Open the rootkitrevealer folder and double-click rootkitrevealer.exe
  • Click the Scan button (bottom right)
  • It may take a while to scan (don't do anything while it's running)
  • When it's done, go up to File > Save. Choose to save it to your desktop.
  • Open rootkitrevealer.txt on your desktop and copy the entire contents and paste them here

Let's head down a slightly different path and see where it takes us.


Download the following file and save to desktop hiving.bat
Immediately sign off the Internet until you are done
Extract the batch file (hiving.bat) within it and run it. If you have script blocking enabled you will get a warning from your antivirus. Please allow this to run. The script is just producing a message box. Double click on the batch to run it. After Reboot the hidden .dll should now be visible and not loaded anymore.


Reboot into Safe mode.


Find this file:
C:\WINDOWS\SYSTEM32\sqlohop.dll
Right click and use the security tab on sqlohop.dll and take ownership.
Change the 'everyone special' to
'you> with Admin rights-> FULL control'
Then try to delete it, if that fails try to rename it first to different name+ext.

Ex: sqlohop.dll -> badsqlohop.badfile

Then you should be able to delete it.



Run CWShredder, making sure to click "Fix".



Reboot back to normal mode and post a new log from DLL Compare.

Let me know how it goes.

Your log looks good to me!

I believe that file was associated with the CWS infection that you had. The tool that you ran mutliple times normally takes care of it, so I'm not sure why it didn't this time. It's possibly a new variant.

I'm just glad it's gone! :tazz:
