For the USB drive:

[*] Download Flash Drive Disinfector and save it to your desktop.
[*] Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
[*] The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.
[*] Wait until it has finished scanning and then exit the program.
[*] Reboot your computer when done.
[*] Note: Flash Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don’t delete this folder… it will help protect your drives from future infection.

For your computer:

  1. Disable System Restore and then reenable it again.
  2. Clean your temporary files.
  3. Schedule a boot time scanning with avast with archive scanning turned on. If avast does not detect it, you can try DrWeb CureIT! instead.
  4. Use SUPERantispyware, MBAM or Spyware Terminator to scan for spywares and trojans. If any infection is detected, better and safer is send the file to Quarantine than to simple delete than.
  5. Test your machine with anti-rootkit applications. I suggest avast! antirootkit or Trend Micro RootkitBuster.
  6. Make a HijackThis log to post here or, better, submit the RunScanner log to to on-line analysis.
  7. Immunize your system with SpywareBlaster or Windows Advanced Care.
  8. Check if you have insecure applications with Secunia Software Inspector.
