Trojan.BHO continues to infect registry

suckpuppet · Jan 10, 2009

Please if you can help remove or prove I'm no longer threatened I would be most appreciative. Thanks.

I have run everything your fine site has suggested and rid my PC of most of whatever first attacked my PC. I think it was trojans: fake-alert and antivirus 2009. MBAM and SAS seemed to have cleaned up most of it along with Combofix.

However, there remains an infected registry key that both MBAM and SAS still find and say they will remove on reboot but are not successful in doing so. I have a feeling that the underlying trojan is still lurking somewhere. I took a risk and tried to delete the key manually using regedit and met resistance from the registry.

I have attached the MBAM and SAS logs. If you have time to help, please let me know which other actions you need and logs...

Your logs are clean....but we need to do a few things;

1) Remove either McAfee or Avira as you should have only one AV program!

2) 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:

O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)

After clicking Fix, exit HJT.

3) Now Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

REGEDIT4

[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{7E853D72-626A-48EC-A868-BA8D5E23E045}]

If you are not having any other malware issues, then:

We recommed you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection, but are effective as backup scanners. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.

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)

Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.

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.

Go to add/remove programs and uninstall HijackThis.

You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip

If you are running Vista, Windows XP or Windows ME, do the below:

Refer to the cleaning steps in the READ ME for your Window version and see the steps to Disable System Restore which will flush your Restore Points.

Then reboot and Enable System Restore to create a new clean Restore Point.

After doing the above, you should work thru the below link:

Thank you for your help. Everything you said makes sense. Unfortunately, I was obsessed with removing that last infected registry key. Rather than wait for your post, I gave regedit a shot. Long story short, I ended up doing a factory restore of my PC, which cleaned out more than just my trojan remnant.

Again, thanks for the help.
