Hi

Just some history before I get to the problem.

A few days ago my computer got infected with the CTFMONA.EXE Virus (blue screen with a box in the middle that said "Warning!! Spyware detected on computer! Install an antivirus or spyware remover!") and BLACKSTER.SCR (a bunch of black bugs that begin to crawl around the screen) but disappear on movement of mouse.

I believe I got infected after installing what I now know as a fake video codec that was meant to help display a video.

After doing abit of internet research I believe I have removed both of these issues, however I'm not 100% sure.

I carried out the following actions:

1) Opened up TASK MANAGER and close CTFMONA.EXE.
2) Went to C:\WINDOWS\SYSTEM32. Found and delete CTFMONA.EXE.
3) From Registry Editor went to CURRENT USER then SOFTWARE > MICROSOFT > WINDOWS > CURRENT VERSION > RUN and selected and deleted CTFMONA.EXE. Close registry.
4) Went into Control Panel then Display Setting and change my screen saver and desktop background back to what they where
5) Went back into the system32 folder. Found and delete BLACKSTER.SCR & CTFMONB.BMP.
6) Shut down and Restart PC

This appears to have removed both these problems.

However when Mcafee runs after start up it detects a Tcad-Crypted (Trojan). It notifies me that the Trojan has been removed but next time I log in the Mcafee detects the same Trojan and notifies me that the Trojan has been removed. Repeats same thing after each log in

Mcafee detection log reads:

Detection name: Tcad-Crypted (Trojan), Tcad-Crypted (Trojan)
File: C:\windows\system32\mssrv32.exe
Process: C:\windows\system32\svchost.exe
Status: Repaired (Removed)

I have downloaded and ran Hijack This. Log File attached. Attached File  hijackthis.log   6.92KB   37 downloads

Could you please check for any nasties and provide some advice.

Regards

Hi Nightrider106. Let's see what we can do. Follow the steps below in order:

Step #1

Please download The Avenger by Swandog46 to your Desktop.
  • Click on Avenger.zip to open the file
  • Extract avenger.exe to your desktop
Copy all the text contained in the code box below to your Clipboard by highlighting it and pressing (Ctrl+C):

Drivers to delete:
msupdate
qmQ62
Files to delete:
%systemroot%\system32\drivers\qmq62.sys
%systemroot%\system32\mssrv32.exe
%systemroot%\system32\winctrl32.dl_
%systemroot%\system32\winctrl32.dll
c:\documents and settings\all users\application data\microsoft\network\downloader\qmgr0.dat
c:\documents and settings\all users\application data\microsoft\network\downloader\qmgr1.dat

Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.

Now, start The Avenger program by clicking on its icon on your desktop.
  • Click in the window labeled Input Scrupt Here and paste the text copied to the clipboard into it by pressing (Ctrl+V).
  • Click the Execute button
  • Answer "Yes" twice when prompted.
The Avenger will automatically do the following:
  • It will Restart your computer. ( In cases where the code to execute contains "Drivers to Unload", The Avenger will actually restart your system twice.)
  • On reboot, it will briefly open a black command window on your desktop, this is normal.
  • After the restart, it creates a log file that should open with the results of Avengerís actions. This log file will be located at C:\avenger.txt
  • The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.
Step #2

Start OTScanIt. Copy/Paste the information in the codebox below into the pane where it says "Paste fix here" and then click the Run Fix button.

[Empty Temp Folders]
[Start Explorer]

The fix should only take a very short time. When the fix is completed a message box will popup either telling you that it is finished, or that a reboot is needed to complete the fix. If the fix is complete, click the Ok button and Notepad will open with a log of actions taken during the fix. Post that log back here in your next reply.
If a reboot is required, click the "Yes" button to reboot the machine. After the reboot, OTScanIt will finish moving any files that could not be moved during the fix and NotePad will open with the final results at that time. Post that log back here in your next reply.

Step #3

Now let's run an online virus scan. Both of these require Internet Explorer. Try F-Secure first. Sometimes it doesn't play nice with other system components so if it cannot complete then try the Kaspersky scan. You only need to complete one of the two.

Run the F-Secure Online Scanner

Note: This Scanner is for Internet Explorer Only!
  • Click on Online Services and then Online Scanner
  • Accept the License Agreement.
  • Once the ActiveX installs,Click Full System Scan
  • Once the download completes,the scan will begin automatically.
  • The scan will take some time to finish,so please be patient.
  • When the scan completes, click the Automatic cleaning (recommended) button.
  • Click the Show Report button and Copy&Paste the entire report in your next reply.
If the F-Secure scan did not work then try an online scan with Kaspersky WebScanner

Click on Kaspersky Online Scanner

You will be prompted to install an ActiveX component from Kaspersky, click Yes.
  • The program will launch and then begin downloading the latest definition files:
  • Once the files have been downloaded click on NEXT
  • Now click on Scan Settings
  • In the scan settings make that the following are selected:
    • Scan using the following Anti-Virus database:
      • Extended (if available otherwise Standard)
    • Scan Options:Scan Archives
      Scan Mail Bases
  • Click OK
  • Now under select a target to scan:Select My Computer
  • The program will start and scan your system.
  • The scan will take a while so be patient and let it run.
  • Once the scan is complete it will display if your system has been infected.
  • Click on the Save as Text button:
  • Save the file to your desktop.
  • Copy and paste that information in your next post.
Step #4

Run a new OTScanIt scan with the following options

Note: You must be logged on to the system with an account that has Administrator privileges to run this program.
  • Close ALL OTHER PROGRAMS.
  • Open the OTScanIt folder and double-click on OTScanIt.exe to start the program.
  • Just use the default settings.
  • Do not change any other settings.
  • Now click the Run Scan button on the toolbar.
  • Let it run unhindered until it finishes.
  • When the scan is complete Notepad will open with the report file loaded in it.
  • Click the Format menu and make sure that Wordwrap is not checked. If it is then click on it to uncheck it and close Notepad (save changes if necessary).
  • Close OTScanIt and locate the OTScanIt.txt file in the folder where OTScanIt.exe is located.
  • Attach that file back here in your next reply.
Step #5

Copy/paste the following back here in your next reply:
  • The Avenger report (c:\Avenger.txt)
  • The latest OTScanIt fix log (look in the OTScanIt folder for the MovedFiles folder. In that folder will be a file with a name in the form of mmddyyyy_hhmmss.log for month, day, year, hours, minutes, and seconds that the scan was run. )
  • The online virus scan report (whichever one you ran)
Attach the following back here in your next reply:
  • The new OTScanIt scan log
I will review the information when it comes back in.

Also let me know of any problems you encountered performing the steps above or any continuing problems you are still having with the computer.

Cheers.

Hi OldTimer

Thanks for the prompt response (much appreciated)

Please find the following reports/logs attached.

Avenger Log
OTScanIT Logs from Steps 2 & 4
F-Secure Online Scanner Report

Yep you were right.... F-Secure Scanner is painfully slow.

Anyhow I hope these reports/logs give you something to work by.

Hi Nightrider106. Everything looks good. Go ahead and run the system normally for a couple of days and then get back with me and let me know if there are any continuing issues. If everything is Ok at that time, then we have some final cleanup to do and you'll be good to go.

Cheers.

Glad to hear it Nightrider106. Then let's do some final cleanup to reset the System Restore points and remove all of the tools we used during the fix and then you are all set.

Step #1

Reset and Re-enable your System Restore to remove infected files that have been backed up by Windows. The files in System Restore are protected to prevent any programs changing those files. This is the only way to clean these files: (You will lose all previous restore points which are likely to be infected)1. Turn off System Restore.On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
Check Turn off System Restore.
Click Apply, and then click OK.
2. Restart your computer.

3. Turn ON System Restore.On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
UN-Check Turn off System Restore.
Click Apply, and then click OK.
[/list]System Restore will now be active again.

Step #2

To remove all of the tools we used and the files and folders they created do the following:
  • Start OTScanIt
    Click the CleanUp button
  • OTScanIt will download a small file from the Internet. If a security program or firewall warns you of this allow it to download.
  • OTScanIt will delete any tools downloaded and files/folders created and then ask you to reboot so it can remove itself. Click Yes.
After that you are good to go.

Cheers and Happy Computing!

Hi OldTimer

Thanks for all your help.

I have carried out your instructions for the final clean and OTScanit and Avenger have been removed.

Hijackthis and ATF Cleaner still remain. In addition to this I downloaded AVG Anti-Rootkit (Free)

Could you please advise as to whether there is any benefit in retaining these programs.

If not, it would be appreciated if you could advise best method for program removal.

Regards

You are very welcome Nightrider106, I'm glad that we could help.

OTScanIt will not remove ATF-Cleaner or HijackThis. It's up to you as to whether or not you want to keep them. ATF-Cleaner is a good tool to use on a regular basis for cleaning out the temp files on the system. With HijackThis, unless you need it in the near future you can delete it. If you do need it again download it at that time.

Unless you are going to use the rootkit scanner for something in the near future there isn't any need for it. Those types of tools are updated continuously so become outdated quickly. When you need it, download it.

I will now close this topic. If you have any new malware related questions or issues in the future please start a new topic.

Cheers and Happy Computing !
