  • If you are asked to reboot the computer to complete the process, click on the Reboot Now button. A report will be automatically saved at the root of the System drive ((usually C:\) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt" (for example, C:\TDSSKiller.2.2.0_20.12.2009_15.31.43_log.txt). Please copy and paste the contents of that file here.
  • If no reboot is required, click on Report. A log file will appear. Please copy and paste the contents of that file in your next reply.

Download http://public.avast.com/~gmerek/aswMBR.exe (aswMBR.exe) to your desktop. Double click the aswMBR.exe to run it

  • Click the "Scan" button to start scan.
  • Upon completion of the scan, click Save log, and save it to your desktop. (Note - do not select any Fix at this time) <- IMPORTANT
  • Please post the contents of that log 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.
