    For the past couple of days I have been having problems with my computer. When it first turns on I get an error message:
    During a scan of files at system startup, potential errors in the system registry were found. p-07-0100 irql: 1f SYSVER 0xff00024
    NT_Kernel error 1256 KMODE_EXCEPTION_NOT_ HANDLED
    Once I press the OK button, I've gotten a couple other error messages as well, usually once I go onto the internet:
    Buffer overrun detected....which then shuts down everything and all I'm left with is the background. Some other saying something about windows performing and illegal opperation and Drmupgds.exe (???) has encountered a problem and needs to close ???????
    As well, I get a lot of pop ups and everything runs very slowly.
    I have run a virus scan with McAfee and nothing has come up. I see other people have had very similar problems and I was hoping you could help me. I am definitely not very good with computers and computer 'language', so any help you can give me would be very appreciated.
    Thanks

    Welcome to Major Geeks!

    It's possible that you have a Vundo infection or possibly a Rustock Rootkit. You will have to try and complete the below to the best of your ability. Even if it is necessary to dowload files to another PC and then transfer them to this PC via CD, USB drive,..etc.


    Please follow the instructions in the below link and attach the requested logs when you finish these instructions.

    thanks for the help, everything seems to be working fine so far, but I will post the logs i got from the combofix and mgtools to make sure everything actually is fine.
    One other thing, not sure if you can help or not, but when i go to 'start' and 'turn off computer' the screen that shows the stand by, turn off or restart doesn't come up if my computer has been on for a while, then it takes a very long time to turn off. ??? that's been going on for quite a while now, before everything else started happening. Not sure if it's anything to be concerned about.
    thanks

    Okay well that removed a load of malware but you still have a bunch to do. Some of the malware has been on here for a long time.

    This may not be malware, but let's finish removing all of your malware before worrying about this.

    Run this Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.

    Run C:\MGtools\analyse.exe by double clicking on it. This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

    R3 - URLSearchHook: Yahoo! Toolbar - {EF99BD32-C1FB-11D2-892F-0090271D4F88} - (no file)
    O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\qttask.exe" -atboottime
    O4 - HKLM\..\Run: [AlcxMonitor] ALCXMNTR.EXE
    O4 - HKLM\..\Run: [SunJavaUpdateSched] "C:\Program Files\Java\jre1.6.0_04\bin\jusched.exe"
    O4 - HKCU\..\Run: [Drmupgds] C:\Program Files\Drmupgds\Drmupgds.exe
    O4 - HKCU\..\Run: [Router] C:\Program Files\Router\Router.exe
    O4 - Startup: PowerReg Scheduler V3.exe
    O8 - Extra context menu item: &Search - ?p=ZUxdm080YYCA

    After clicking Fix, exit HJT.


    Now we need to use ComboFix to remove a bunch of malware files.
    • 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.
    • 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:
    Driver::
    hesvc
    DirLook::
    C:\Temp
     
    File::
    C:\Program Files\Drmupgds\Drmupgds.exe
    C:\Program Files\Router\Router.exe
    C:\WINDOWS\system32\REN1B97.tmp
    C:\WINDOWS\system32\REN1B96.tmp
    C:\WINDOWS\system32\aglsefoy.dll
    C:\WINDOWS\system32\drivers\hesvc.sys
    C:\Program Files\AlfaCleaner\ACServer.exe
    C:\WINDOWS\moqrss.ini
    C:\WINDOWS\mrofinu572.exe.tmp
    C:\WINDOWS\nprsru.ini
    C:\WINDOWS\ppprqr.ini
    C:\WINDOWS\suuvxx.ini
    C:\WINDOWS\vxwwvw.ini
    
    Folder::
    C:\Documents and Settings\All Users\Application Data\Viewpoint
    C:\Documents and Settings\Compaq_Owner\Application Data\Viewpoint
    C:\Program Files\Router
    C:\Program Files\Drmupgds
    C:\Program Files\AlfaCleaner
     
    Registry::
    [-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{A95B2816-1D7E-4561-A202-68C0DE02353A}]
    [-HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\winlogon\notify\aglsefoy]
    
    • 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.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    • 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!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it.

    Then attach the below logs:
    • C:\ComboFix.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!
