my name is Junwen. My portable hard disk is infected with the Win32/Dorkbot!Lnk worm. I did a scan with MSE and it gave me this result. I deleted the worm as instructedby MSE however my hard disk is still in the same state. The worm kept producing a Recycler folder, which i deleted and created a folder with the same name, to prevent this Recycler folder from reappearing. I followed this tip on the Internet. There is an autorun.inf file which i deleted as well.

This "dorkbot" worm hide all my files and i know they are still there because my hard disk's capacity is still the same prior to infection, and the folders can still be accessed if type the pathway in the search box. I tried a program called "unhide" but my folders still remain hidden.

I am really at my wits end. Any tech whiz or kind soul please help me! :(

Hi junwen, welcome to the forum.

To make cleaning this machine easier
  • Please do not uninstall/install any programs unless asked to
    It is more difficult when files/programs are appearing in/disappearing from the logs.
  • Please do not run any scans other than those requested
  • Please follow all instructions in the order posted
  • All logs/reports, etc.. must be posted in Notepad. Please ensure that word wrap is unchecked. In notepad click format, uncheck word wrap if it is checked.
  • Do not attach any logs/reports, etc.. unless specifically requested to do so.
  • If you have problems with or do not understand the instructions, Please ask before continuing.
  • Please stay with this thread until given the All Clear. A absence of symptoms does not mean a clean machine.
*Note: if this is a Vista or Win7 computer you must right click the .exe and click "Run as Administrator" instead of double clicking.

Do not use any temporary file cleaners until instructed to do so.

Download OTL to your desktop.
  • Double click on OTL.exe to run it. Make sure all other windows are closed and to let it run uninterrupted.
  • When the window appears, underneath Output at the top change it to Minimal Output
  • Check the boxes beside LOP Check and Purity Check.
  • In the window under Custom Scans/Fixes copy and paste the following

    %systemroot%\*. /mp /s
    %PROGRAMFILES%\bak. /s
    %systemroot%\system32\bak. /s
    %ALLUSERSPROFILE%\Start Menu\*.lîk /x
    %systemroot%\system32\config\systemprofile\*.dat /x
    %PROGRAMFILES%\Internet Explorer\*.dat
    %APPDATA%\Mikzosoft\Internet Explorer\Quick Launch\*.lnk /x
    %PROGRAMFILES%\Common Files\*.*
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install|LastSuccessTime /rs
    %USERPROFILE%\..|smtmp;true;true;true /FP
    %temp%\smtmp\*.* /s >

  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply. You may need two posts to fit them all in.

Download aswMBR.exe to your desktop.

Double click the aswMBR.exe to run it

Click the "Scan" button to start scan

On completion of the scan click save log, save it to your desktop and post in your next reply

There shall also be a file on your desktop named MBR.dat. Right click that file and select Send To>Compressed (zipped) folder. Please attach that zipped file in your next reply.

Please post back with
  • both OTL log
