WinXP - "windows installer" continual popup, slow PC

Did you disable automatic updates yourself?

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::

DirLook::
c:\documents and settings\ron\Application Data\BC95B571D294CAFFF94F028B373FD7BC
Registry::
[HKEY_CURRENT_USER\software\microsoft\windows\currentversion\run-]
"updateMgr"=-
[HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\run-]
"HPBootOp"=-
"HP Software Update"=-
"MSConfig"=-
"PCDrProfiler"=-
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{AF69DE43-7D58-4638-B6FA-CE66B5AD205D}]

• 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 folder except ones from the current date (Windows will not let you delete the files from the current day).

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

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. Combofix dealt with infected files and replaced them so things should be okay now.

Don't forget to answer my question regarding the auto updates.

 

Do you have your operating disk handy?

This infection is turning out to be a right pain! Because of this, and not wanting to make any mistakes in my mission to help you, I am going to point Chaslang at this thread and let him see what he thinks. We have been replacing the files from recovery console, with the OS CD but at the moment, all combofix reported was an infected winlogon.exe. We don't know what ELSE is infected also, not to mention all the connected registry entries.

Let's sit tight a while and see what Chas says.

 

Download and save this XPsp2bu.exe to your C:\ root folder. You must do this properly. Now run the XPsp2bu.exe program by double clicking on it. You may or may not notice a quick flash of a black window. This is normal. The program runs quickly and just extracts some files we need.

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.

 

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

C:\MGtools\temp\winlogon.exemg | c:\windows\system32\winlogon.exe
Folder::
c:\documents and settings\ron\Application Data\BC95B571D294CAFFF94F028B373FD7BC

You need to run the CF script again, in normal mode if possible or in safe mode if need be. Then...

 

1. Restart your computer.
2. When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
3. At this menu, select the option for Safe Mode with Command Prompt using the arrow keys and then press Enter key on your keyboard.
4. Perform whatever tasks you require and when you are done restart your computer into normal mode.

Let me know how you get on, I don't know what's happening with combofix saying there's incorrect spelling, I have had that occur three times now this morning, one with your thread, and two others.

 

Looking great now!

Okay, just to cover everything, let's have you run an ESET scan now, and see if it turns up anything else that could be wrong, which I do doubt now.

Now run this:
Using ESET's Online Scanner

 

Okay that found more Bamital, so... please run ESET twice more and attach logs.

Then...
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.

 

Pardon me, you are correct about ESET, I flashed through earlier and what ESET found was the infected files which combofix had in it's quarantine after I had it fix it. Reviewing your logs now...

 

OK then, onto final steps!

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:
