Trying to clean up infected computer

Welcome to Major Geeks!

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:

O4 - HKCU\..\Run: [MSMSGS] "C:\Program Files\Messenger\msmsgs.exe" /background
O20 - AppInit_DLLs: ljngkv.dll

NOTE: HJT may popup an error about the AppInit_DLLs line. Ignore it and click OK to continue.

After clicking Fix, exit HJT.

Run this Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.


Now we need to use ComboFix again.

• 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.
• Open Notepad and copy/paste the text in the below quote box into it:

• 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.


Now run Ccleaner to remove temp files!

Now download the new version of MGtools and overwrite your previous MGtools.exe file with this one.

Run MGtools.exe ( Note: If using Vista make sure UAC is still disabled. Also don't double click on it, use right click and select Run As Administrator )


Now attach the below log:

• C:\ComboFix.txt
• C:\MGlogs.zip

Make sure you tell me how things are working now!

 

You have not attached the two logs yet.

 

Okay there is a strange folder that I had ComboFix list the contents of. Do you know what the below are? Were the dates of these files around the time of your 1st problems?

Code:

---- Directory of c:\windows\system32\.750df4c0f1ad62b6 ----
2009-03-26 06:52 45 -a-- c:\windows\system32\.750df4c0f1ad62b6\750df4c0f1ad62b6.ServerPlugin.config 
2009-03-26 06:52 180 -a-- c:\windows\system32\.750df4c0f1ad62b6\750df4c0f1ad62b6.AT.config 
2009-03-24 22:04 22016 --h- c:\windows\system32\.750df4c0f1ad62b6\750df4c0f1ad62b6.exe 

Also why are the below ports all opened? Are you an online gamer or a torrent or P2P downloader?

 

Yes I will give steps below but also consider stopping the use of torrents or any other P2P downloaders which are quite possible the source of your infections and are probably the largest single cause of people coming here with malware problems.




Now we need to use ComboFix again.

• 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.
• Open Notepad and copy/paste the text in the below quote box into it:

• 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.


Now attach the new c:\combofix.txt log.

 

Run the below:

Disabling AutoRuns

Also you need to scan all USB flash drives or other removable devices (even memory cards for digital cameras or MP3 players) for infections. Also any additional PCs these devices were plugged into may be infected.

 

You're welcome. Your 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.
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.
   • Delete the C:\combofix folder from combofix (if it exists)
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. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
9. 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.
10. After doing the above, you should work thru the below link:
