    1. You are infected, maybe download the ESET program from a normal comp & put it on a thumb drive.

      C:\Windows\Temp\2.exe

      I shall go through the HJT log now.

    2. HJT log is Ok, but modern infections can hide very efficiently.

      Here are some basic methods to check for infections & slowness.
      See if they fix your problem, if not, shall have to dig further.

    3. If SFC dos’nt fix the problem, more googling gets this as a possible, it is the only 2.exe in your HJT log.

      Revo in Advanced mode will uninstall everything, including registry entries.

      Revo Uninstaller

      Open Revo, double click on a program logo, click > Yes & then you get your options, with Advanced down the bottom.
      If you have partially uninstalled your program, you get a message from Revo, that it can’t find the uninstaller, hit Cancel & let Revo continue on, to search for the remnants.
      If you get a reboot message, ignore it & do it after Revo has finished.
      I use Advanced Mode. Screenshots of how to use.
