    So having issues and ran combofix. It told me I had rootkit.zeroaccess

    So it ran rebooted and after it was done I couldn't get an IP address from the network tried ipconfig, widows network fix etc. nothing. So ran combofix again still said I had rootkit.zeroaccess it finished and rebooted still no IP so I ran again it rebooted and still no IP.

    So here are the logs I have so far, no idea where to go from here. I checked all the other threads about it and didn't really help since they all included steps that said warning for the poster only.

    Help would be greatly appreciated.

    Well I got impatient and carried on without your sage advice.

    I deleted netbt.sys I removed registry containing netbt and I rebooted. Ohh boy then it got fun no network device. I found netbt.bat in your mgtools folder and ran that, it rebooted and viola it worked internet access and apparent clean system. So I ran malwarebytes and still looks good. I will run avenger and fss and mgtools again and post the reports so you can double check me.

    Thanks for the response and hopefully going on ahead did not screw things up worse (it doesn't appear so) It will be tonight before logs get posted as I am heading out to work.

    Thanks again

    You're logs are clean.


    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 oof 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 or Win 7, 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:
