Re: Possible Trojan - PLS Help!

Hi,

Please copy this page to Notepad and save to your desktop for reference as you will not have any browsers open while you are carrying out portions of these instructions.

It's IMPORTANT to carry out the instructions in the sequence listed below.

***************************************************

*Download SDFix and save it to your Desktop. Double click SDFix.exe and it will extract the files to %systemdrive% -(Drive that contains the Windows Directory, typically C:\SDFix). Do not run it yet.

--------------------------------------------------------------------

1) Restart your computer into Safe Mode.
2) After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
3) Instead of Windows loading as normal, a menu should appear
4) Use the up arrow key to highlight Safe Mode and press Enter.
5) Login with your usual account. Make sure to close any open browsers.

--------------------------------------------------------------------

Open the extracted SDFix folder and double click RunThis.bat to start the script.
  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt I'll need that in your next reply.
--------------------------------------------------------------------

From Normal Mode...

Open notepad and copy/paste the text in the quotebox below into it:

Quote:
File::
C:\WINDOWS\system32\pgd.dll
C:\WINDOWS\system32\drivers\fee

Folder::
C:\Program Files\Tyzhnddw
C:\Program Files\Qoswziws
C:\Program Files\Pfpkguqy
C:\Program Files\Isebbczd
C:\Program Files\Gwzlwfym
C:\Program Files\Bhmoxunj
C:\Program Files\qnanojwt

Registry::
[-HKEY_LOCAL_MACHINE\~\Browser Helper Objects\{38D55A70-E975-996F-2411-01092EBA6C2B}]
[-HKEY_LOCAL_MACHINE\~\Browser Helper Objects\{5C2290D4-C3F1-4bb5-91E6-D0B806A8663A}]
[-HKEY_LOCAL_MACHINE\~\Browser Helper Objects\{ED12044A-04F8-44BF-A394-8D4D04B2F93D}]
[-HKEY_LOCAL_MACHINE\~\Browser Helper Objects\{F369DA09-FADE-44CB-987F-E2E0DEF51BCA}]
[-HKEY_LOCAL_MACHINE\~\Browser Helper Objects\{7E853D72-626A-48EC-A868-BA8D5E23E045}]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"iss7328"=-
"ykmyegiy"=-
"btmnixix"=-
"dcadqtgp"=-
[HKEY_USERS\.default\software\microsoft\windows\currentversion\run]
"Scbu"=-
[-HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\winlogon\notify\winjcr32]
[-HKEY_LOCAL_MACHINE\software\microsoft\shared tools\msconfig\startupreg\Ultimate Fixer]
Save this as CFScript.txt, in the same location as ComboFix.exe




Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt

Note:
Do not mouseclick combofix's window whilst it's running. That may cause it to stall


--------------------------------------------------------------------

We'll need to run an online scan to search for any remnants that may be lurking about. Using Internet Explorer, visit http://www.kaspersky.com/service?chapter=161739400

Answer Yes, when prompted to install an ActiveX component.
  • The program will then begin downloading the latest definition files.
  • Once the files have been downloaded click on NEXT
  • Locate the Scan Settings button & configure to:
    • Scan using the following Anti-Virus database:
      • Extended
    • Scan Options:
      • Scan Archives
      • Scan Mail Bases
  • Click OK & have it scan My Computer
  • Once the scan is complete, it will display if your system has been infected. It does not provide an option to clean/disinfect. We only require a report from it.



  • Click the Save as Text button to save the file to your desktop so that you may post it in your next reply
* Turn off the real time scanner of any existing antivirus program while performing the online scan
