    There are two problems that i have encountered and are driving me up the wall,
    The first is popups, normally Winantivirus2006, drivecleaner or sys protect being the worst out of the three, that actually downloads the program onto my pc, ive heard that these popups are more than just that, they are related to viruses or spyware that download themselves onto pc's and make up problems until you purchase the so called "cleaner",
    I browse the same sites, and have never had these popups before, if i close them they get worse and keep coming back,

    The second problem is explorer.exe, that i have never noticed before in windows task manager, but has suddenly started using up all my CPU and ram, whilst im browsing the internet,it seems to happen every 10 secs or so, and my pc will go really slow, i think its related to the popups as this happened after them,
    Explorer.exe can be related to a virus too,

    I have done all the steps stated in removing basic spyware, malware and viruses, Explorer.exe seems to have stopped but the popups haven't :(

    Here are the results in the attachements and hopefully this can be sorted out,

    Thanks for your time,

    Welcome to Majorgeeks!

    You need to attach the other two logs that were requested in step 6. The GetRunKey and ShowNew logs.

    Explorer.exe is always running on a PC. It is your Windows shell. Without it, you would have no Desktop, no icons, no Start button, not tray,....etc. It is also Windows Explorer (the file manager) when open subsequently after startup. This is what you see when you double click My Computer or right click Start and select Explore.

    You have a Virtumonde infection and remnants of a winlogonhook infection that we need to remove.

    Please download and install Registrar Lite Make sure you select a Majorgeeks download link and not the Authors!

    Run Registrar Lite navigate to the following key and take ownership of it (explained further down):

    HKEY_LOCAL_MACHINE\software\microsoft\mssmgr

    To take ownership of the key do the following:
    • Copy & Paste the registry key from above into the address bar of Registrar Lite and hit the enter key. This will bring you to the registry key.
    • Click-on Security in the Menu
    • Select Take Ownership
    • Now leave RegistrarLite running and continue
    • Now run the REGISTRY PATCH below in this message.
    • Tell me the results. Any error messages?
    • Now in RegistrarLite click View and then Refresh
    • Now navigate to HKEY_LOCAL_MACHINE\software\microsoft\mssmgr
    • Does the above mssmgr key still exist! If so, right click on it and select Delete.
    Here is the Registry Patch

    Now Copy the bold text below to notepad. Save it as fixWLK.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

    After completing ALL of the above instructions, continue here!

    Start by downloading two tools we will need

    - Process Explorer

    - Pocket KillBox

    Extract them to their own folder somewhere that you will be able to locate them later.

    IMPORTANT: You should print or save the below locally, so you can refer to them while offline. You must exit all browsers before running the below steps and it would be best if you actually physically unplug your cable to the internet, reboot, and do not run anything but what I give you to do. Also it would be good to exit all processes and items in your System tray.

    Do the above before continuing! Okay unplug your cable now.

    Make sure you have rebooted in Normal Mode (do not open any other processes)

    - Run Process Explorer

    In the top section of the Process Explorer screen double click on winlogon.exe to bring up the winlogon.exe properties screen. Click on the Threads tab at the top.

    Once you see this screen click on each instance of awvts.dll once and then click the kill button. After you have killed all of the awvts.dll under winlogon click ok. (If you do not find the dll, just continue on.)

    Now repeat the above step for the below DLLs (If you do not find the dll, just continue on):
    wvuvvts.dll

    Next double click on explorer.exe and again click once on each instance of awvts.dll and kill it. (If you do not find the dll, just continue on.)

    Now repeat the above step for the below DLLs (If you do not find the dll, just continue on):
    wvuvvts.dll

    Now just exit Process Explorer.

    Run HijackThis 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:

    R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant =
    O2 - BHO: (no name) - {9D39D03A-7F98-40F7-8B92-E086859C7DF4} - C:\WINDOWS\system32\awvts.dll
    O3 - Toolbar: (no name) - {BA52B914-B692-46c4-B683-905236F6F655} - (no file)
    O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\qttask.exe" -atboottime
    O4 - HKLM\..\RunOnce: [eISS_TestValue] 1
    O20 - Winlogon Notify: awvts - C:\WINDOWS\system32\awvts.dll
    O20 - Winlogon Notify: wineak32 - wineak32.dll (file missing)


    After clicking Fix, exit HJT.

    Now we need to Reset Web Settings:
    1. If you have an Internet Explorer icon on your Desktop, goto step 2. If not, skip to step 3.
    2. Now right click on your desktop Internet Explorer icon and select Properties. Then click the Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK. Then skip step 3.
    3. If you do not have an Internet Explorer icon on your Desktop, click Start, Control Panel (for some systems it may be Start, Settings, Control Panel), Internet Options, Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK.
    Note for IE 7 users: You need to select Internet Options then the Advanced tab and then Reset Internet Explorer Settings!

    Copy the bold text below to notepad. Save it as fixme.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.
    Now run Pocket Killbox by doubleclicking on killbox.exe
    Choose Tools > Delete Temp Files and click Delete Selected Temp Files.
    Then after it deletes the files click the Exit (Save Settings) button.
    Now back on Killbox's main window, Paste the below filenames into KILL BOX one at a time. Check mark the box that says "Delete on Reboot" and checkmark the box "Unregister DLL" (If available) Click the RED X and it will ask you to confirm the file for deletion…say YES and when the next box opens prompting you to reboot now...click NO...and proceed with the next file. Once you get to the last one click YES and it will reboot. Note some of the files listed below may not exist but we need to check for them anyway.

    C:\WINDOWS\Downloaded Program Files\UDC6_0001_D18M1108NetInstaller.exe
    C:\WINDOWS\Downloaded Program Files\UDC6_0001_D18M1108NetInstaller.inf
    C:\WINDOWS\Downloaded Program Files\USYP_0003_N91M0908NetInstaller.exe
    C:\WINDOWS\Downloaded Program Files\UWA6P_0001_N91M1807NetInstaller.exe
    C:\Windows\System32\Narrator.exe
    C:\WINDOWS\system32\abjidbpv.exe
    C:\WINDOWS\system32\cplqevly.exe
    C:\WINDOWS\system32\lkyutnon.exe
    C:\WINDOWS\system32\lrggtwbi.exe
    C:\WINDOWS\system32\nakowvaq.exe
    C:\WINDOWS\system32\paarsfft.exe
    C:\WINDOWS\system32\awvts.dll
    C:\WINDOWS\system32\wvuvvts.dll
    C:\WINDOWS\system32\stvwa.ini
    C:\WINDOWS\system32\stvwa.ini2
    C:\WINDOWS\system32\stvwa.tmp
    C:\WINDOWS\streamhlp.dll


    If Killbox does not reboot or if you get a Pending Operations type error message just click OK to continue and then just reboot your PC yourself.


    Also delete all files in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    C:\WINDOWS\Temp
    C:\Documents and Settings\Rick\Local Settings\Temp


    Now attach a new HJT log and tell me how the steps went.

    Also attach a new log from ShowNew and a new log from GetRunKey.

    Make sure you tell me how things are working now!
