@Barril100

You said that OTL log is too big so upload it to RapidShare: https://rapidshare.com/

What about MBAM ? Is it clean ? If not, attached log please.

Hi,

Step1
Download TDSSKiller  and save it to your desktop

    Execute TDSSKiller.exe by doubleclicking on it.

  •     Press Start Scan

     
  •   If Suspicious object is detected, the default action will be Skip, click on Continue.
     
  •   If Malicious objects are found, select Cure.
Once complete, a log will be produced at the root drive which is typically C:\ ,for example, C:\TDSSKiller.<version_date_time>log.txt


Please post the contents of that log in your next reply.

@Barri100

Con TDSSKiller si encuentra algo sospechoso no hagas nada. Si es Malicioso curalo.

Notepad es " Bloc de nota " copia/pega el codigo y guardas el bloc de nota como.... " CFScript.txt "
