    I've picked up an infection this morning that it appears a few others have as well. Initially it featured processes including b.exe amongst others and reg keys for Monopod. It has disabled my virus scanner, Symantec AntiVirus amongst other problems. I've followed the Removal Guide as much as it will let me.

    Steps 1-5 of the removal guide were no probs, but the program seems bent of preventing me following the Windows XP Cleaning Procedure.

    SuperAntiSpyware - Started scan, the program just disappeared.
    Attempting to reopen gives - Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item. Alternate startup gives no sign of action.

    Malwarebytes Anti-Malware - Started preparing for scan then died.
    Attempting to reopen gives - Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item.

    ComboFix - Got to attempting to create restore point then died. I can start this one up again multiple times, but with the same result.

    RootRepeal - Got further than any of the other programs, was scanning windows directories and died.
    Attempting to reopen gives - Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item.

    MGtools - Started, but seems to stop mid-way through the process. Having checked other zip files, it seems like mine is not able to call all the pieces it needs. It doesn't result in any error, just disappears. I tried the fix for error message one, as incomplete logs was a symptom of my problem, but there was no change.

    I tried booting in safe mode, but couldn't get a different result there either. I checked my scecli.dll, as others have had problems hiding there, but mine is 181,248 bytes, which I think was the correct size.

    In conclusion, I don't know where to start. Whatever it is it seems nasty. Thanks so much for any help you can offer.

    Welcome to Major Geeks!

    I'm going to give you some steps to follow. You MUST follow these steps exactly and they MUST be performed in the order written. I suggest that you read thru all of it first before running any steps.
    1. Download The Avenger by Swandog46, and save it to your Desktop.
    2. Extract avenger.exe from the Zip file and save it to your desktop but DO NOT RUN IT.
    3. Now download and save the below two files to the root folder of your Windows boot drive. Normally this would be drive C. If you do this correctly, you will then see C:\MGtools.exe and FixAVP.exe You need to redownload this MGtools file because it is a new version. Just overwrite your previous version.
    4. Now run MGtools.exe by following the instructions given here Using MGtools which will help your understand how to run it and what will happen. You don't need to worry about attaching the MGlogs.zip file that it mentions yet because we have more to do and new log will be obtained later.
    5. Now run the FixAVP.exe file by double clicking on it. This will attempt to automatically run Avenger (which you downloaded above) and it should also try to reboot your PC so don't be alarmed when this happens.
    6. After Reboot, and if all goes well, a new scan by MGtools should automatically take place because Avenger will try to run C:\MGtools\GetLogs.bat which will begin all the scans again.
    7. When GetLogs.bat finishes running, there will be a new C:\MGlogs.zip file and now it will be time to attach it to your next message. Make sure that you allow GetLogs.bat to finish running. It will tell you when it is finished. Do not close the command prompt window on your own until it is finished.

    I think I beat this, but didn't post updates to avoid being moved to the back of the queue. I got ComboFix to run somehow and it seems to have fixed the problems. I re-installed the other programs from the instructions and they seem to have run fine and come back clean. Looks like the culprit was hiding in eventlog.dll.

    Here are the logs recorded. Let me know if I should still follow the instructions from your post.

    Yes this infection can use the eventlog.dll file or it could also use netlogon.dll or scecli.dll. It is just a matter of which form you get.

    Your logs are basically clean but I do suggest that you delete the below task file:
    C:\WINDOWS\Tasks\{6A85C18A-344B-4A30-86EB-4F54F2FE7786}_BETA_User.job

    Also you need to get properly protected before you get infected again. The below steps will cover this.

    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 protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we used Pocket Killbox during your cleanup, do the below
      • Run Pocket Killbox and select File, Cleanup, Delete All Backups
    3. 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" /u
        • Notes: The space between the combofix" and the /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. 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.
    6. Go to add/remove programs and uninstall HijackThis.
    7. 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.
    8. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures in step 3 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.
    9. After doing the above, you should work thru the below link:
