Problem started with: "NT Authority/System Shutdown" and now multiple problems

Malware Bytes and SUPERAntiSpyware didn't find much but that is more than likely because they are VERY out of date.

Open up MBAM > click on the Update tab > let it update > install new version when prompted to do so > run a scan > let it fix all it finds and attach the log from doing so.

Now do this:

Important Notice: A new version of SUPERAntiSpyware is available.

• Please uninstall your current version (this is necessary).
• Then download this SUPERAntiSpyware
• Install this new version. It may tell you that you need to reboot to complete the installation. You must reboot at this time.
• After the reboot, run SUPERAntiSpyware and immediately click the Check for Updates button to get more updates for the database.
• Now run a new full scan of your system. And attach this log later.

Now I want you to boot into safe mode and see if you can get first Combofix to run, and then MGTools.exe. Let me know what happens, and attach logs if you are successful.

 

1. Before we continue I would like for you to use MSConfig to put this machine back into normal start up mode, if you haven't done so already.

2. I want you to follow my next instructions in normal mode now please, and not safe mode.

3. Please go to Add and Remove programs and uninstall the following software:

• Java(TM) 6 Update 6

4. You need to see that you tidy up the C Drive a bit. I see alot of files scattered about on there that could well be in their own folders or put into folders in another location.

5. Now we need to use ComboFix

• 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.
• Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
• If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
• Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:

Code:

KILLALL::

Fcopy::
C:\WINDOWS\SoftwareDistribution\Download\dd9ab5193501484cf5e6884fa1d22f9e\atapi.sys | C:\WINDOWS\system32\drivers\atapi.sys

• 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.

6. Now reboot your machine and install the most current and up to date version of Java available here at the below link:

Java Runtime 6

7. Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from Combofix.

Are you getting the "NT Authority/System Shutdown" error anymore?

8. Let us know of any problems you may have encountered with the above instructions and also let me know how things are running now!

 

I am referring to files/folders like the below:

The likes of these should all be in their own directories and moved to "My Documents" or someplace other than your C Drive. This will keep things nice and tidy for your benefit

Okay, let's do this:

Download the MBR Rootkit Detector to your desktop.

• Doubleclick mbr.exe and follow prompts.
• A black DOS window will quickly appear then disappear.
• When mbr.exe is finished it will create a log on your desktop.
• Copy and paste contents of that log file to your next reply.

 

Good afternoon

Well, it's entirely your choice, we have a list to choose from in the "How to protect yourself from Malware" link which will be provided in my final steps.

I use PCTools on my XP machine and with the Vista I just use the Windows Own firewall. In any case, your logs are malware free:

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" /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.
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 6 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:
    • How to Protect yourself from malware! <--- take a look here for recommended firewalls

 

You're welcome. Safe surfing

 

When I click on Firefox it takes a while for the browser to pop up as well.
When I gave you final steps I was happy you were malware free. You may wish to visit the software forum to discuss slowness.
