AVG reported this found on 9th September but I only noticed today when the internet failed to react and I checked AVG. The internet will not work on ie and I am sending this via Firefox.

The full AVG message is:-
File: C:\WINDOWS\SYSTEM32\userinit.exe
Infection: Trojan horse Downloader.Generic10.QLN
Result: Object is whitelisted (critical/system file that should not be removed).

I have downloaded Malwarebyte from my Netbook but although it loads it will not run.

I should also mention that I am getting a Generic Host process for Win32 Services error which I understand occurs in XP service pack 2 - I have SP3 so this should not need the patch??

Can you help please.

Hello and welcome.. Try this approach.

Reboot into Safe Mode with Networking
How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
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.
Select the option for Safe Mode with Networking using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.


>>>> Download this file and doubleclick on it to run it. Allow the information to be merged with the registry.

RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply
Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.



Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Please ask any needed questions,post logs and Let us know how the PC is running now.

Thank you for that.

The problem is on my computer at home, so I will try your solutions this evening. I will download the programs at work and transfer them to the desktop as Firefox has now been disabled by this virus at home!

Ok,will look back later.

Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine..

Note: Mbam-rules.exe is not updated daily. Another way to get the most current database definitions if you're having problems updating through the program's interface or have already manually downloaded the latest definitions (mbam-rules.exe) shown on this page, is to do the following: Install MBAM on a clean computer, launch the program and update through MBAM's interface. Copy the definitions (rules.ref) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system. If you cannot see the folder, then you may have to Reconfigure Windows to show it.
  • XP: C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware
  • Vista: C:\Documents and Settings\Users\All Users\Malwarebytes\Malwarebytes' Anti-Malware

Hi Boopme

Thanks for your help so far. No luck I'm afraid. I followed your instructions to the letter (of course).

Fixexe reg seemed to go as predicted.

I ran RKill from all three locations and got the following report each time:-

This log file is located at C:\rkill.log.
Please post this only if requested to by the person helping you.
Otherwise you can close this log when you wish.
Ran as David on 13/09/10 at 17:44:33.


Services Stopped:


Processes terminated by Rkill or while it was running:


C:\Documents and Settings\David\Desktop\rkill.scr


Rkill completed on 13/09/10 at 17:44:40.

Next I tried to run SUPERAntiSpyware but it would not run the "Normal" version. It did however run the portable scanner apparently successfully. I did not note the result, but seem to remember about 6 Trojans and one other malware which is a pity because when I went to the logs page and there was nothing listed at all! Even though stuff was found and deleted. I also looked into Quarantined iterms and there is nothing there either.

I then rebooted the computer transferred across the up to date files for Malwarebyte but again it refuses to run.

Finally I ran another SUPERAntispyware check which ran through completely clear.

I still have the Generic Host process for Win32 Services message.

Thanks for your continued help, looks like a real tough one.

Hello ,we are running XP or Vista here?

Let's do an online scan.

ESET
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the ESET Online Scanner button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Export to text file... to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Eset Smart Installer icon on your desktop.
  • Check the "YES, I accept the Terms of Use"
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Check Scan archives
  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push "List of found threats"
  • Push "Export to text file", and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the "<<Back" button.
  • Push Finish
In your next reply, please include the following:
  • Eset Scan Log


NOTE: In some instances if no malware is found there will be no log produced.

No that does not work I'm afraid - I can only get on the Internet long enough to get to the enet page but when I tried to run the program a pale blue rectangle appeared which was blank with "done" in the bottom left hand corner. The Internet cannot then be accessed and all the buttons at the bottom of my screen go very big and black.

I am running Windows XP

Hello ,I believe we can fix this by Un and Re installing SP3. This will probably fix all issues.
Uninstall
Click Windows Start >> Control Panel.

Click Add or Remove Programs and open Programs and Applications. Click small box at top, Show Updates.

Click Service Pack 3 > > Remove/Uninstall >> Yes.
When done restart your computer.

Reinstall
Go here and scroll to Turn on Automatic Updates
http://support.microsoft.com/kb/322389

The best way to obtain Windows XP SP3 is to turn on the Automatic Updates feature in Windows XP. To have us turn on Automatic Updates for you, go to the Fix it for me on left.

Fix it for me
To fix this problem automatically, click the Fix this problem link. Then click Run in the File Download dialog box, and follow the steps in this wizard.

OK, when I try to remove SP3 I get a warning and click OK;then a box appears which says:
Setup detected the following programs on your computer.

Avast
Lots of security updates
Update for Windows XP
Hotfix for Windows XP
Microsoft NET Framework 11 security update
Malwarebyte's AntiMalware
MapNeto1Toolbar
Microsoft office Publisher 2007
TomTomHome
MIcrosoft Visual C++ 2008
MYOB Accounting V10

If SP3 is removed these programs might not run properly. Do you want to continue?

I clicked yes and the software update removal wizard froze on "Inspecting Current Configuration " from 6.55pm to 7.10 is this normal?

The cursor is a pointer not a hand.

OK,I asked some colleagues. You may still have a Bamital infection that will prevent this.
Let's wait a bit (30 minutes or so) to see if it doesn't move on. This really can take a while.

If it is really frozen, just abort the uninstall.


Now

Please do a search for c:\windows\system32\hlp.dat

I left it for almost 2 hours with no joy. I scrolled down to c:\windows\system32\ but there is no hlp.dat file unless I am looking for it the wrong way..

Edit to add - I just did a search for all hlp.dat files on the computer and there are none

Defogger seemed to work OK but unfortunately dds.scr opened and said it would take no more than three minutes. The screen then disappeared but after 10 minutes no log has opened.


Just to add - I ran dds.scr on my work computer to see what happens and I notice there should be a row of ==== signs before the logs are produced. Nothing like that on the home machine, screen just disappeared!
