Please put ComboFix directly on your desktop, not where you are running it from:
Running from: c:\downloads\ComboFix.exe

What told you you had a rootkit? Do you have a log to attach that I could look at?

Go to the below link and follow the instructions for running TDSSKiller from Kaspersky

• TDSSkiller - How to run

Be sure to attach your log from TDSSKiller

Please also download MBRCheck to your desktop.

See the download links under this icon http://forums.majorgeeks.com/chaslang/images/MGDownloadLoc.gif

• Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
• It will show a Black screen with some information that will contain either the below line if no problem is found:
  
  • Done! Press ENTER to exit...
• Or you will see more information like below if a problem is found:
  
  • Found non-standard or infected MBR.
  • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
• Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
• MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.
• Attach this log to your next message. (See: HOW TO: Attach Items To Your Post )
