Symptoms: (XP on recent service pack 3)
=========

Cookies lost (deleted?) or expiring strangely early.

Automatic Updates would not stay turned off! (I had to resort to disabling the service)

A very occasionally (boot time only) pop up showing adds from -

adserving.cpxinteractive.com

MS Spy showed a hidden window with, in the header

www.cdcdcdcdc2121cdsfdfd.com

AVG 8 found nothing!, Ad-Adware 2008 found nothing! and I could see nothing out of place on my HiJackThis.log

Then under Task Manager - Processes, I found

_QBOTNTI.EXE x 3
_QBOTINJ.EXE

(should have spotted these earlier)

Which the web told me might be found in -

c:\documents and settings\all users\_qbothome

which also contained a nasty log of my logins to various sites !!!

Removal:
=======
- disconnected from the net
- killed the four tasks within task manager
- tried and failed to delete the files
- renamed _qbothome
- then COULD delete the files and folder
- reboot

Automatic Updates now do stay turned off!

I anyone wants to tell me (and others) what I should have done then please do. :thumbsup:

These errors and symptoms are about identical to mine.

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 keeps 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 http://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.

Any help or direction is MUCH appreciated.
Thank you kindly.

Hello let's see if we can get a log from MBAM. Here are some tricks if needed.
Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run..


***
Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.
***
Open up command prompt, type in following commands:
XP >> click the Start menu at the lower-left of your computer's desktop and select "Run". Type cmd into the Run box and click "OK".
Vista >> click the Start menu at the lower-left of your computer's desktop and Type cmd in the search box.

regsvr32 mbamext.dll
regsvr32 ssubtmr6.dll
regsvr32 vbalsgrid6.ocx
regsvr32 zlib.dll

****

If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.

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.

***
Try using a System Retore Point prior to the date of infection. You may be able to update and run MBam. Note this did not remove the malware.
Windows XP System Restore Guide


Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.35) 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.
