This is goingt to be a little difficult as I`m not familiar with Windows 64.
However, I have idntified some nasty entries in your HJT log.
Download the Pocket Killbox programme from
HERE. Extract it but don`t run it yet.
You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.
Boot into safe mode. See how HERE.

Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.
Click on the processes tab and end process for(if there).
1b78249f.exe
Close task manager.
Run HJT with no other programmes open(except notepad).Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).
F2 - REG:system.ini: UserInit=userinit
O4 - HKLM\..\Run: [1b78249f.exe] C:\WINDOWS\SysWow64\1b78249f.exe
O4 - HKCU\..\Run: [Mddi] "C:\WINDOWS\DOBE~1\iexplore.exe" -vt yax
O4 - HKCU\..\Run: [Clg] C:\PROGRA~2\FNTS~1\TSKMGR~1.EXE
Fix all O18 - Protocol: entries.
O20 - AppInit_DLLs: C:\WINDOWS\system32\nopdb.dll
O20 - Winlogon Notify: winuns32 - C:\WINDOWS\SYSTEM32\winuns32.dll
Click on the fix checked button.
Close HJT.
Run the killbox.exe file. When it loads type the full path to the file you would like to delete in the field and check the delete file on reboot button. press the Delete File button (looks like a red circle with a white X). It will prompt you to reboot, select no until you have finished inputting the files you want to delete, only then allow it to reboot and hopefully your files will now be deleted.
These are the filepaths you need to enter into killbox.
C:\WINDOWS\SYSTEM32\winuns32.dll
C:\WINDOWS\system32\nopdb.dll
C:\WINDOWS\SysWow64\1b78249f.exe
Once your system has rebooted, turn system restore back on and post a fresh HJT log.
Let us know how your system is running.
