computer freezes and malware

Hi there and welcome. I am currently reviewing your logs and will get back to you with a set of instructions in the next post I make to you.

 

Why is it that you do not currently have any antivirus installed? I see traces left from avg but that was from a few months back now.

If you did not deliberately set this proxy yourself then please include it in the HJT fix below:

Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) 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:

After clicking Fix exit HJT.

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::

File::
C:\SZKGFS.dat
C:\WINDOWS\system32\123.js
C:\WINDOWS\system32\179EE1D2A4.sys
C:\WINDOWS\system32\abtsvchost.xml
C:\WINDOWS\system32\8da6~1 
C:\WINDOWS\system32\svchost.exe.exp.log
c:\documents and settings\All Users\SPL2.tmp
c:\documents and settings\All Users\SPLDA.tmp
c:\documents and settings\All Users\SPL1.tmp
c:\documents and settings\All Users\SPL64.tmp
c:\documents and settings\All Users\SPL1F.tmp
c:\documents and settings\All Users\SPL5.tmp
c:\documents and settings\All Users\SPL18.tmp
c:\documents and settings\All Users\SPLC.tmp
c:\documents and settings\All Users\SPL69.tmp
Registry::
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"SvrWsc"=-
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{C84D72FE-E17D-4195-BB24-76C02E2E7C4E}]

• 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.

Also delete all files in the below bold folders except ones from the current date (Windows will not let you delete the files from the current day).

• Click Start, select Run
• In the box, type cmd
• Click OK
• Run the chkdsk utility by typing in the following command:
• chkdsk c: /f /r

This can take a long time so be patient and let it run through to completion.

Please also download MBRCheck to your desktop

• Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
• It will show a Black screen with some data on it
• Right click on the screen and select > Select All
• Press Control+C
• Open a notepad and press Control+V
• now please ATTACH that report to this thread

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.

Let me know how things are running for you now.

 

Now boot to the Recovery Console and run the fixmbr to clear a Master Boot Record infection that you have.

You can read the below to help you do this:

After running the fixmbr command and boot back to normal mode, continue with the below.

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.

 

Re-run MBRCheck for me please and attach the log.

 

That's better.

Now uninstall the below outdated version of Java.

Java(TM) 6 Update 22

Reboot your machine and install the most current and up to date version of Java available here at the below link:

Java Runtime 6

Run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

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:
