    Hello -- it appears our home computer was infected with this a couple days ago. Have kept it turned off until I could get decent guide to help clean it up. I've read the "read me's" and I think I've done everything requested to the best of my ability. I've been getting the AVG warning about this since I turned the computer back on up until I had to uninstall AVG to get some of the downloads to work. Here are the log files -- any help you can offer is appreciated. Thank you very much.

    Delete this file:

    C:\ProgramData\Microsoft\Windows\DRM\7ABC.tmp

    NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

    Attached is fixlist.txt
    • Save fixlist.txt to your flash drive.

    Now re-enter System Recovery Options.

    • Now re-run RogueKiller - no fix just a scan and attach the log.
    • Re-run FRST - no fix, just a scan and attach the log.

    Ok, here are the new logs.

    I don't currently have internet access on the infected computer (brought it to office to do this). I had to uninstall AVG to get the fix programs downloaded and working and I didn't want to install a new one until you said it was ok to do so. I've been reading your forums for recommendations on AV, etc and will install new one as soon as you say ok and then I'll do some browsing to see how things are working. Let me know if you'd rather me take a different approach.

    Thanks again, SG

    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 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:
