    Hello and welcome to Techspot.

    Very Important: Before deciding whether you should clean or reformat your system, go and read this thread HERE and decide what it is you want to do.

    If after reading the above, you wish to clean your system, do the following.

    Go and read the Viruses/Spyware/Malware, preliminary removal instructions. Follow all the instructions exactly.

    Post fresh HJT, AVG Antispyware and Combofix logs as attachments into this thread, only after doing the above.

    Also, let me know the results of the AVG Antirootkit scan.

    Regards Howard :wave: :wave:

    You didn`t post an AVG Antispyware log as requested. Please do so in your next reply.

    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, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how HERE.

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

    Click start/run and type services.msc into the run box and press the enter key.

    When the window appears, maximise it. Double click on the following services(if there) and select stop if they are running. Set the startup type to disabled. Click apply/ok for each service you disable.

    FireDaemon Service: ecure (ecure)

    Close the services window.

    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).

    FireDaemon.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).

    R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = *.local

    O3 - Toolbar: Protection Bar - {F06E2ABE-3A50-4079-BE25-FC100D9EAA25} - C:\Program Files\Video ActiveX Access\iesbpl.dll (file missing)

    O20 - AppInit_DLLs: C:\WINDOWS\system32\__c00C1B32.dat

    O22 - SharedTaskScheduler: biltongs - {fc7cbb1b-2da6-4e7d-a1ea-bf6705dd0f8c} - C:\WINDOWS\system32\fyhwfc.dll (file missing)

    O23 - Service: FireDaemon Service: ecure (ecure) - Unknown owner - C:\WINDOWS\Temp\FireDaemon.EXE (file missing)

    Click on the fix checked button.

    Close HJT.

    Locate and delete the following bold files and/or directories(if there).

    C:\WINDOWS\Temp\FireDaemon.EXE
    C:\WINDOWS\system32\fyhwfc.dll
    C:\WINDOWS\system32\__c00C1B32.dat
    C:\Program Files\Video ActiveX Access<Delete the entire folder.

    Reboot into normal mode and rehide your protected OS files.

    Post fresh HJT and AVG Antispyware logs.

    Regards Howard :)

    You have posted your HJT log from safe mode. I need to see a fresh HJT log from normal mode.

    Run the Ccleaner programme as per step9 of the instructions in this thread HERE.
