Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should not have any open browsers when you are following the procedures below.

Before you do anything else, please create a folder for HijackThis and put it in a permanent folder (like C:\HJT) instead of the Temp folder. This is required because HijackThis will create backups and we don't want them to be deleted.

The Temp folders should be cleaned out periodically as installation programs and hijack programs leave a lot of junk there. Download CleanUp! (Alternate Link if main link don't work) and install it. You will use this later.

Please download Ad-aware SE and install it if you don't have it already. Make sure it's the newest version and check for any updates before running it. Also go here to get the plug-in for fixing VX2 variants. To run this tool, go into Ad-aware->Add-ons and select VX2 Cleaner. Then click Run Tool and OK to start it. If it's clean, it will say Status System Clean. Otherwise, you will have to click on the Clean button to remove the VX2 infection. Also make sure to customize the settings in Ad-aware for better scan results. Run the scan and fix everything that it finds.

Download and install Spybot S&D. Run Spybot and click on the 'Search for Updates' button. Install any updates that are available. Next click on the 'Check for Problems' button. Let it run the scan. If it finds something, check all those in RED and hit the Fix Selected Problems button. Exit Spybot. If you keep getting the DSO Exploit entries, even after you updated Windows and fixed them, then download the Spybot DSO Exploit Fix and install it over the current Spybot installation.

Go to My Computer->View->Folder Options->View tab and make sure that 'Show all files' is checked under the 'Hidden Files' section. Also make sure there is no checkmark beside 'Hide file extensions for known file types'.

For the options that you checked/enabled earlier, you may uncheck them after your log is clean. If we ask you to fix a program that you use or want to keep, please post back saying that (we don't know every program that exists, so we may tell you to delete a program that we think is bad to keep).

Go to Start->Settings->Control Panel and double-click on the System icon. On the Performance tab click File System. Click the Troubleshooting tab, and then check Disable System Restore. Click OK. Click Yes when you are prompted to restart Windows. When we have confirmed that your log file is clean, you may enable System Restore again by following the same steps as above except you should uncheck Disable System Restore.

Reboot into Safe Mode (hit F8 key until menu shows up). Make sure to close any open browsers. Go into HijackThis->Config->Misc. Tools->Open process manager. Select the following and click Kill process for each one if they are still listed (they shouldn't be - but double check it):

C:\WINDOWS\SYSTEM\NHCGINAXU.EXE

Uninstall the following via the Add/Remove Panel (Start->(Settings)->Control Panel->Add/Remove Programs) if they exist:

EliteToolBar
EliteSideBar

Run a scan in HijackThis. Check each of the following and hit 'Fix checked' (after checking them) if they still exist (make sure not to miss any):

R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant =
R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch =

O16 - DPF: {1D0D9077-3798-49BB-9058-393499174D5D} - file://c:\counter.cab

Delete the following Files/Folders (delete folders if no filename is specified) according to their directory (if none, just do a search for them) and delete them if they exist:

C:\WINDOWS\SYSTEM\NHCGINAXU.EXE
C:\PROGRAM FILES\BZK9KUO9
c:\counter.cab

Run CleanUp! and click on CleanUp! button. When it asks you if you want to logoff, click on Yes.

Reboot into Normal Mode and run new HijackThis scan. If there were some entries that didn't show up in Safe Mode, you may check and fix those that appear now in normal mode (if you do that, make sure to run a new scan again). Save the log file and run KRC HijackThis Analyzer in the same folder to get the result.txt log. Just post the contents of the result.txt file in the forum.
