    It is an extremely bad idea to allow all users to have Admin. privileges!! You need to run both SAS and MBAM on each user account. Attach any logs that find malware, being sure to identify the user account.

    You have some services running that seem to be from sysinternals.com, but I don't believe they are legit:
    O23 - Service: TEF - Sysinternals - www.sysinternals.com - C:\DOCUME~1\ANDY\LOCALS~1\Temp\TEF.exe
    O23 - Service: VBHNZSPOPRXMHKA - Sysinternals - www.sysinternals.com - C:\DOCUME~1\ANDY\LOCALS~1\Temp\VBHNZSPOPRXMHKA.exe
    O23 - Service: XTHCAZBWUPW - Sysinternals - www.sysinternals.com - C:\DOCUME~1\ANDY\LOCALS~1\Temp\XTHCAZBWUPW.exe

    * Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
    If it is not on your Desktop, the below will not work.
    * Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    * If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
    * Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    Code:
    KILLALL::
    Driver::
    TEF
    VBHNZSPOPRXMHKA
    XTHCAZBWUPW
    IHPXWXQMRVH
    
    File::
    C:\Documents and Settings\ANDY\Local Settings\Temp\TEF.exe
    C:\Documents and Settings\ANDY\Local Settings\Temp\VBHNZSPOPRXMHKA.exe
    C:\Documents and Settings\ANDY\Local Settings\Temp\XTHCAZBWUPW.exe
    C:\WINDOWS\system32\LQARWNVRN
    C:\WINDOWS\system32\PHENBUPT
    C:\WINDOWS\system32\ZFRCUAPJ
    
    * Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    * At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    * You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    If it asks you to overide the previous file with the same name, click YES.
    * Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    [​IMG]
    * Follow the prompts.
    * When it finishes, a log will be produced named c:\combofix.txt
    * I will ask for this log below

    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.

    Now run Ccleaner to clean out only temp files and nothing else!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:

    * C:\ComboFix.txt
    * C:\MGlogs.zip

    Make sure you tell me how things are working now!

    Can you now see that allowing all users to have Admin. privileges means any malware coming into one of those accounts will spread to all the other accounts? You need to change most of the accounts to limited.

    Have you disabled all disc emulation software? I am seeing a MBR infection that may be a false positive if you haven't.

    Let's have you do this, as the HelpAssistant user is active:

    Please download HelpAsst_mebroot_fix.exe and save it to your desktop.
    Close out all other open programs and windows.
    Double click the file to run it and follow any prompts.
    If the tool detects an mbr infection, please allow it to run mbr -f and shutdown your computer.
    Upon restarting, please wait about 5 minutes, click Start>Run and type the following bolded command, then hit Enter.

    helpasst -mbrt

    Make sure you leave a space between helpasst and -mbrt !
    When it completes, a log will open.
    Please post the contents of that log.


    *In the event the tool does not detect an mbr infection and completes, click Start>Run and type the following bolded command, then hit Enter.

    mbr -f

    Now, please do the Start>Run>mbr -f command a second time.
    Now shut down the computer (do not restart, but shut it down), wait a few minutes then start it back up.
    Give it about 5 minutes, then click Start>Run and type the following bolded command, then hit Enter.

    helpasst -mbrt

    Make sure you leave a space between helpasst and -mbrt !
    When it completes, a log will open.
    Please post the contents of that log.

    No matter what happens with the above, attach the above logs and then immediately continue with the below in normal boot mode!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:

    * C:\MGlogs.zip

    Make sure you tell me how things are working now!

    I had a problem with that mebroot thing earlier this year, I thought I got rid of all of it and fixed it with the recovery console. I disabled all my disc emulation stuff earlier with defogger, so there should be no false positives.

    I looks like that took care of it. Are you having any other malware issues?

    If you are not having any other malware problems, it is time to do our final steps:

    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.


    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.

    10. After doing the above, you should work thru the below link:
