I am running Windows XP SP3, and earlier this week I discovered these malicious processes running: _qbotinj.exe, and experienced errors and symptoms which led me to search the internet for solutions.

I successfully deleted the _qbotinj.exe process, files and parent folders, and decided to install AVG after some people recommended it.

But for some reason I can't even install AVG because it keeps claiming that this "application" cdcdcdcdc2121cdsfdfd.com - Internet Explorer is running, and cannot seem to be terminated (even if I disable IE).

So since I cannot scan using AVG, I am using Symantec Antivirus, which is still detecting a "Trojan Horse" virus in this location:
C:\Documents and Settings\All Users\_qbothome\_qbotinj.exe

Although there is NO folder for _qbothome, no process running for _qbotinj.exe or anything. (since I deleted it days ago)

How can I locate this phantom file that Symantec keeps finding? Does it exist, or have I successfully deleted it? If so, why do I keep getting warnings?

And is it perhaps related to this <hxxp://www.cdcdcdcdc2121cdsfdfd.com/> application that seems to be stuck? Check the whois.sc database for that URL and you can see the dudes name, address, and company that seems to be the source of this wack url.

Although my AVG install wizard is the only place that detects this hidden cdcdcdcdc2121cdsfdfd.com window, I am very worried about its possible relationship to this "Trojan Horse" threat that Symantec Antivirus keeps detecting.

Here is the warning message I receive from my AntiVirus:

Scan type: Realtime Protection Scan
Event: Virus Found!
Virus name: Trojan Horse
File: C:\Documents and Settings\All Users\_qbothome\_qbotinj.exe
Location: C:\Documents and Settings\All Users\_qbothome
Action taken: Clean failed : Quarantine failed : Access denied
Date found: Saturday, March 28, 2009 8:29:30 AM

Again, I cannot find a folder for _qbothome, or no process running for _qbotinj.exe or anything. (since I deleted it days ago)

Any help or direction is MUCH appreciated.
Thank you kindly, and please let me know if I ought to provide any more info.

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the 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.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.


No. Try not. Do... or do not. There is no try.
