    If you turned off system restore,and you ran HJT in safe mode,then you can fix it as suggested (in safe mode)

    Also Go into HJT->Config->Misc. Tools->Open process manager and if you see this-
    C:\WINDOWS\system32\?hkdsk.exe Kill it.

    I did ask you to start a new thread. However, since you`ve posted you fresh HJT log here, I`ll deal with it here.

    Boot into safe mode. See how HERE.

    Turn off system restore.(XP/ME only) See how HERE.

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

    Go to add remove programmes in your control panel and uninstall anything to do with(if there).


    Close control panel.

    Click start/run and type regsvr32 /u C:\WINDOWS\system32\dla\tfswshx.dll into the run box and press the enter key. Note the space between the 2 and the forward slash and again between the u and c.

    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).


    Close task manager.

    Run HJT with no other programmes open. Have HJT fix the following, by placing a tick in the little box next to(if there).
