I think I'm infected with the ctfmon32.exe thing. I have scanned my computer several times with spybot (fully updated) and with spysweeper (also updated, but no virus scan), and even Trendmicro (with virus scan). None of them have been able to catch it.

whenever I restart my computer, spybot will have a popup window that says something with a change in the registry and this program is trying to startup. So I look for more info and it says that it's the ctfmon32.exe, that is some sort of malware or spyware. After I click, "deny change", other spybot warning windows appear, showing the following application names also indicated as being changed in the registry: SsAAD.exe and TkBell.exe. Each time I have put deny change.

These are just 3 of the main windows that appear from spybot, there were another 4 or so. But these have since stopped appearing when I attempted to delete the ctfmon32.exe thing by running my computer on safe mode based on advice from bleepingcomputer website.

So, how can I make sure I don't have this bugger anymore?

HOpe someone can help!

Please download MsnCleaner.zip and save to you Desktop. (in addition to removing infected files, it will remove certain restrictions on your system often disabled by malware.)
  • Extract (unzip) the file to your desktop. (click here if you're not sure how to do this) but DO NOT use it yet.
  • Reboot your computer in "Safe Mode" using the F8. To do this restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A boot menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".
  • Double-click MsnCleaner.exe to run the tool.
  • Click the "Analyze" button.
  • A report will be created after the scan and will be saved to C:\MsnCleaner.txt.
  • If it finds an infection, click the "Deleted" button.
  • Reboot normally and post the contents of MsnCleaner.txt in your next reply.

Here is the report from MSNCleaner. When I ran it in safe mode, and again in normal mode, it produced the same report...that there were no infected files. However, once again, when I rebooted the computer in normal mode, the same Spybot window popped up indicating that there was a change in the registry by ctfmon.exe. So I had to deny the change again.

- Logfile MSNCleaner 1.6.9 by www.forospyware.com
- Created Logfile: 8/10/2008 on 1:17:48 AM
- Operative System: Windows XP
- Boot mode: Normal

So, I'm not sure what is going on.

SsAAD.exe is related Sony's Digital Music Manager software.
TkBell.exe is the Application Scheduler installed with RealOne Player.

I'm not sure what registry changes were made that Spybot detected from what you have posted.

ctfmon32.exe is not good. MSN cleaner looks for it in the Windows directory. Did you do a physical search of your system for that file? If not, please do so.

You can use Windows Search feature > More advanced options to see if the file(s) are still present. To do this, go to Start -> Search and click For Files or Folders... or just press the Windows key + F key on the keyboard.
  • Click All files and folders.
  • Type in the name of the file under "Search by...criteria."
  • Click More advanced options and check these options:
    • "Search system folders"
    • "Search hidden files and folders"
    • "Search subfolders"
  • Then click "Search" to look for the file(s).
Let me know what you find.

Ok, I did a file search as you advised and the file name has not been found. So, why does spybot keep posting pop up warnings that the ctfmon32.exe is still there? This is the warning shown on spybot, I copied it word for word:

Spybot - Search & Destroy has detected an important registry entry that has been changed.

Category: System Startup User Entry
Change: Value Changed
Entry: ctfmon.exe
Old Data: "C:\Windows\system32\ctfmon.exe"
New Data: C:\Windows\system32\ctfmon.exe

And once I click on "info", this is what I see:
Current filename: C:\Windows\system32\ctfmon.exe
Database status: not required - virus, spyware, malware or other resource hog
Value: ctfmon.exe
Filename: ctfmon32.exe

Description: CoolWebSearch ctfmon32.exe parasite variant
Source: Paul Collins Startup List

I deny the change, and it still keeps popping up every time I restart the computer.
Also, a few days ago, I deleted a strange program called: "kdfmgr.exe" which has a little diamond looking icon next to it and another associated file called "kdfvmgr.exe". Are these dangerous programs? possibly related to the ctfmon32.exe? And there was a time when something popped up showing something about DrWatsonsAntispyware program. And the english on the popup was horrendous.

What do you make of all this?

If you are using Trend Micro with Transaction Protector, kdfmgr.exe is related to Keystroke Encryption. See here. If not, its probably a malicious Trojan.

According to Prevx, kdfvmgr.exe refers to many versions of an executable program.

However, when kdfvmgr.exe is seen with kdfmgr.exe, the following .dlls also seem to be present:
C:\WINDOWS\system32\kdfinj.dll
C:\WINDOWS\system32\kdfapi.dll
C:\WINDOWS\system32\Kdfhok.dll

From my research, all five files appear to be created the same date/time.

The legit ctfmon.exe is 15 KB and usually dated 8/04/04. If you right-click on it and choose properties. the Mircosoft version should show: 5.1.2600.2180

I recommend further investigation. Before that can be done you will need you to create and post a hijackthis log.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log" and complete all the steps. There are instructions for downloading and running Deckard's System Scanner (DSS) which will create a hijackthis log for you, or automatically download and install the most current version of HijackThis if it's not already installed on your computer.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Your hijackthis log is posted here.

Now that your log is posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

To avoid confusion, I am closing this topic until you are cleared by the HJT Team. If you still need assistance after your log has been reviewed and you have been cleared, please PM me or another moderator and we will re-open this topic.

Good luck with your log.
