Hi looks like you have two for the price of one

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following


    Quote
    :OTL
    O4:64bit: - HKLM..\Run: [hcoas] rundll32.exe "C:\Users\MingYao\AppData\Roaming\hcoas.dll",GetCounter File not found
    [2012/08/02 02:21:04 | 000,020,480 | ---- | C] (Microsoft Corporation) -- C:\Windows\svchost.exe

    :Files
    ipconfig /flushdns /c
    C:\Windows\assembly\GAC_32\Desktop.ini
    C:\Windows\assembly\GAC_64\Desktop.ini
    C:\Windows\Installer\{d0c53142-f0bb-d4a9-c005-233073b7f0c1}
    C:\Users\MingYao\AppData\Local\{d0c53142-f0bb-d4a9-c005-233073b7f0c1}

    :Commands
    [purity]
    [resethosts]
    [emptytemp]
    [CREATERESTOREPOINT]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
  • Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.
THEN

Download the latest version of TDSSKiller from here and save it to your Desktop.
 
 
  • Doubleclick on TDSSKiller.exe to run the application


  • Then click on Change parameters.
     

     
  • Check the boxes beside Verify Driver Digital Signature and Detect TDLFS file system, then click OK.
     
  • Click the Start Scan button.
     
     
  • If a suspicious object is detected, the default action will be Skip, click on Continue.
     

     
  • If malicious objects are found, they will show in the Scan results and offer three (3) options.
  • Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.

  • Get the report by selecting Reports

 
  • Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
Please copy and paste its contents on your next reply.

FINALLY

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1
Link 2
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
  • Accept the disclaimer and allow to update if it asks




  • When finished, it shall produce a log for you.
  • Please include the C:\ComboFix.txt in your next reply.[/b]
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.


Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now
