Was infected with at least scribble-B virus a month ago and backed up files to jump drive. Was able to disinfect first virus but when I used the USB drive to reinstall files it came back within minutes of plugging in - seems to be more resistant to cures now. Can't run MBAM and a host of others. No desktop even in safemode, no restore point. Can't boot with Kaspersky or Avira disc. Attaching HJT log.
